To start, open up your file in Photoshop. This is a pretty lumpy scale and not very useful for a photograph. It is typically recommended that you use the Save As option to save a copy of the new bit depth file so that you can keep a copy of the original file just in case any changes need to be made. Skip the 32-bit working space, unless you are using it as a way to combine multiple RAW files and then multi-process them as 16-bit layers (HDR workflows). But Im not a big fan of speculating, so Ive done a lot of testing. First is the original 14-bit RAW, which is about 6.5 stops underexposed. A better option would be 30-48 bits (aka Deep Color), which is 10-16 bits/channel -with anything over 10 bits/channel being overkill for display in my opinion. So go with 16-bits. Monitor vendors want to make their equipment sound sexy, so they typically refer to displays with 8-bits/channel as 24-bit (because you have 3 channels with 8-bits each, which can be used to create roughly 16MM colors). I would generally recommend merging to HDR in Lightroom instead of using 32-bit Photoshop files. So I set both to +4 exposure and then adjusted the RAW curve to bring in the white point to 50%. A bit is a computers way of storing information as a 1 or 0. Or, simplify luminosity maskingwithLumenzia: See thestorepage for Lumenzia and course info.Lumenzia and Greg Benz Photography are registered trademarks of Greg Benz Photography LLC.Seelicensingfor Commercial and Creative Commons (Non-Commercial, Attribution) Licensing terms.Join myaffiliateprogram.See myethics and privacystatement. There are 3 channels in an RGB image. The government is asking for 24 bits total (not per channel). Since CMYK mode has 4 color channels instead of 3, you can expect a larger file size than you would with an RGB mode image. The rest of the photo would still (in reality) be 8-bit, but the sky gradient would be true 16-bit. There is no immediate visual difference. There is no 16-bit option for the gradient tool in Photoshop, it is a 12-bit tool internally (but 12-bits is more than enough for any practical work, as it allows for 4096 values). Want all of our free Photoshop videos? In the new window, select the List All Modes button. In Photoshop select save for web, once the window pops up on the preset . As you apply Curves or other adjustments, you are expanding the tonal range of various parts of the image. 4. For several reasons: Based on the discussion above, it should be clear that 8-bits is not enough. Good to hear this display issue will be fixed today, but this is NOT saving it as a preference for a new file. There is of course noise in the image, but this is actually a printable file (though certainly not ideal). And second, when there is risk of banding in your photo (eg a smooth backdrop, or a blue sky). Using dithering will often reduce the appearance of banding if your bands are close to 1 pixel wide (ie, dithering wont hide bands in documents above a certain resolution; a Nikon D850 file is almost twice as wide as you would need to display every value in a 12-bit gradient). Color Space determines the maximum values or range (commonly known as gamut). Next, select the Image tab from the menu bar at the top of the screen and find Mode. Photography software (such as Photoshop and Lightroom) refer to the number of bits per channel. So while this result is ok, it is just shy of a disaster. Photoshops gradient tool will create 12-bit gradients in 16-bit document mode. Switching it to 16-bit fixes it. The first version (on top) is the processed 14-bit image. See my post on false banding to learn how to avoid any confusion. This next variant is the processed 12-bit image. I wouldnt be surprised if you are not getting 16-bit accuracy from a 16-bit file, but that is speculation on my part. Photoshop layers are like sheets of stacked acetate. And if you convert color spaces, be aware that there is a dithering option for 8-bit images under Edit / Color Settings / Conversion Options. Because the information is stored in each pixel, that means that the file size increases with the color depth. The final image shows a residual color cast and greater contrast (with the shadow behind the towel being most notable). I then manually corrected the image the best I could, but there were no white balance settings which looked fully correct nor matched the 14-bit file. But seriously, the above method isnt necessary. There are other ranges as well, such as 12-bit and 14-bit, but these arent used in Photoshop, so we wont get into them here. So your conference still only has 80 attendees, but now theyre all sitting many metres apart from each other, and the whole thing is completely pointless. A single bit isnt really good for anything beyond yes or no because it can only have 2 values. For that reason, it is worth using a wider gamut now so that your working file can take advantage of better printers and monitors later, such as ProPhoto RGB. The same would apply to monitors and printers, which may get better bit-depth and gamut in the future. For the most part, 16-bit images allow for the most tonal range without exceeding printer capabilities. Noise is a very good example of this discrepancy. But neither is really necessary, and Ive done plenty of high-end work on a standard monitor. (You may be aware that it uses 16-bit floating point math in order to cover a wider dynamic range with a similar number of bits. As a general rule, the more colors (higher bit) that an image has, the smoother the transitions between tones and the less banding that is present. The simple truth is, if you want 16-bit data, you have to start with 16-bit data that is, by exporting in 16-bit mode from Raw. This means that instead of 2^16 possible values (which would be 65,536 possible values) there are only 2^15+1 possible values (which is 32,768 +1 = 32,769 possible values). Color monitors allowed more vibrant displays, but color depth was still limited. Two scenarios come to mind where 16-bit mode is helpful. To describe something complex, we can combine multiple bits. Color space is gamut (the range over which the bits are applied), so a very large gamut could theoretically cause banding if it stretches your bits too thin. For example . For one, it would be a lot of work to develop both Photoshop and file formats to support other bit depths. I just set it to 16-bit pasted a file, then CTRL-N and it was 8-bit again. It would be convenient if all bit-depths could be compared directly, but there are some variations in terminology that are helpful to understand . As a simple analogy, pouring a small glass of water into a bigger glass doesn't give you more water - it just gives you a partially-filled big glass. If you really want to maximize your bits, check out the betaRGB or eciRGB v2 profiles (which contain all print/display colors with much less waste than ProPhoto). But ProPhoto is a well-defined standard worthy of consideration, so does it create jumps large enough to cause banding issues? With a 16-bit workflow, I see no reason to worry about banding/posterization with ProPhoto RGB and I use ProPhoto RGB as my primary color space these days. If you dont see banding on your monitor after conversion to 8-bits, you should be ok to print. The futility of the exercise. But if youre familiar with mathematics, youll know that even a 10-bit file has a hell of a lot more data than an 8-bit file.). First, make sure the mode is set to RGB Color. Whenever I create a new file it automatically creates it in 16 bit depth, and I never think about it until I either go to use filter gallery or transfer my sketches to illustrator to refine and I cannot import it as layers. 2-bit images are typically called bitmaps, and they contain only . Be sure to calibrate the monitor though if you are sending files out for print. The recommended 16-bits for working files should remain sufficient for a few reasons: (1) thats greater than most monitors and printers are or will be in the foreseeable future and (2) beyond the limits of our ability to see differences. Ultimately, I find that at ISO 64 with a Nikon D850: As I generally try to avoid more than 3 stops of shadow recovery due to noise, the color cast due to 12-bit files is rarely going to be an issue in my work. First, those times when you unavoidably need to make aggressive adjustments to your photo in Photoshop, rather than in raw. As of Photoshop CS5, a maximum of 32-bits can be used. In reality, 8-bits is fine for final print output. Ive done "terrible things" to 8-bit Jpegs (edited them really aggressively) and they turned out fine. The New Layer settings should be sticky so you can use the previous settings and amend the size for the next. Even if the source has been degraded, processing in 16-bits will still yield better results as it will minimize compounding of rounding errors in the math with multiple adjustments. Photoshop offers 8, 16, and 32-bit file formats. This will cause Photoshop to open the file in 16-bit mode when you're done processing the RAW file. Color depth simply refers to the highest number of colors an image can hold. I rarely would adjust RAW exposure out to +/-4 stops, but it can happen with extreme situations or portions of poor exposures. So there is an advantage to shooting with a 14-bit file on the Nikon D850, but it is relatively slight under extreme conditions. That holds true even if you are using an 8-bit source file (such as a stock image downloaded in JPG). Here's an example of the canvas vs layer view in 8-bit mode. No conversion necissary. Conversion of the final edited image to 8-bits is perfectly fine, and has the advantage of creating much smaller files in the internet for faster uploads/downloads. A color image is typically composed of red, green, and blue pixels to create color. You are recommended to select a color mode with higher bit depth to display more colors and get a better visual experience. If youre not familiar with bit depth, read this article. Lightrooms HDR DNG format is perfectly fine to use. Much more concerning though is the splotchy color noise (which you can see in the lighter part of the towel shadow below). Well, it does and it doesnt. Here in my Windows 11, it is Display adapter properties for Display 1. According to Adobe developer Chris Cox, this allows Photoshop to work much more quickly and provides an exact midpoint for the range, which is helpful for blend modes). Of course, youll need to be on the lookout for it so that it doesnt sneak into a print. I then processed the images in Lightroom (LR) using exposure and white balance adjustments. Images with 32 Bits/Channel are . A while back I was messing with some settings in photoshop and must have accidently done something wrong. Bit depth tells Photoshop how many colors an image can contain. I havent spent the time to investigate how it all nets out when you factor in log-scaling used on the data, but my sense is that using ProPhoto is roughly like throwing roughly 1-bit of data. /t5/photoshop-ecosystem-discussions/how-to-change-default-bit-depth/td-p/10969301, /t5/photoshop-ecosystem-discussions/how-to-change-default-bit-depth/m-p/10969326#M312968, /t5/photoshop-ecosystem-discussions/how-to-change-default-bit-depth/m-p/10969335#M312970, /t5/photoshop-ecosystem-discussions/how-to-change-default-bit-depth/m-p/10969331#M312969, /t5/photoshop-ecosystem-discussions/how-to-change-default-bit-depth/m-p/10969338#M312971, /t5/photoshop-ecosystem-discussions/how-to-change-default-bit-depth/m-p/10969408#M312984, /t5/photoshop-ecosystem-discussions/how-to-change-default-bit-depth/m-p/12895433#M638441, /t5/photoshop-ecosystem-discussions/how-to-change-default-bit-depth/m-p/12895463#M638448, /t5/photoshop-ecosystem-discussions/how-to-change-default-bit-depth/m-p/12895534#M638459. It probably looks pure black to you, but if you look closely, youll see theres some detail. Below are some extreme examples from my testing. YouTube: https://www.youtube.com/user/OreillyMediaFacebook: https://www.facebook.com/OReilly/?fref=tsTwitter: https://twitter.com/OReillyMediaWebsite: http://www.oreilly.com/ There's no such thing as a 24 bit depth image really in general usage. Each channel is 8 bits so any RGB image that's 8 bit would be. Photoshop lists the bit depth as Bits/Channel. Table 1. Yes, Photoshop does allow you to convert your 8-bit file to 16-bit, but it doesn't truly turn it into 16-bit data. An 8-bit gradient is relatively easy to see when looking for it, though I might still potentially miss it if I werent paying attention. If we significantly brighten the shadows or darken the highlights, then we are expanding some portion of the range. So, for my purposes, a 10-bit gradient is visually identical to 14-bits or more. If you were to use a box of crayons as an example, greater bit-depth would be like having more shades (more crayons) and greater gamut would be like having the most saturated color be more bold (regardless of the number of crayons). It is always important to validate your assumptions. If you follow the recommendations above, it is very unlikely you will run into banding. -- ~K All rights reserved. Most cameras raw data is actually 10, 12 or 14-bit, which Photoshop puts into that 16-bit "wrapper" that I mentioned earlier. In addition to 8 Bits/Channel images, Photoshop can also work with images that contain 16 or 32 Bits/Channel.. When you combine 3 bits, you can have eight possible values (000, 001, 010, 011, 100, 101, 110, and 111). I would recommend making all other changes (flattening, color space conversion, sharpening, etc) before conversion to 8-bits. But personally, Im sticking with ProPhoto. With a clean gradient (ie, worst case conditions), I can personally detect banding in a 9-bit gradient (which is 2,048 shades of gray) on both my 2018 MacBook Pro Retina display and my 10-bit Eizo monitor. If you really want or need 16-bit, shoot raw and process it in 16-bit, the way everyone else does. There is no reason to use 32-bits for photography unless you are processing an HDR file. It is possible to see banding immediately in 8-bits. Also, tweaking the white balance just slightly more than I have here started to show some large grey splotches in the wood of the door. 2-Bit. Bit-depth determines the number of possible values or increments. But most importantly, there are huge benefits to using a file format with a few extra bits (as well discuss later). Here's an example of the canvas vs layer view in 8-bit mode. A single bit has 2 possible values, 0 or 1. In general, the number of possible choices is 2 raised to the number of bits. Results from other cameras are likely to vary, and the differences are ISO-dependent so you should test with your own camera. The limiting factor is your RAW conversion software, not Photoshop. Each of these colors is handled by your computer and monitor as a channel. This may be helpful if working in an 8-bit file. THANK YOU. If you convert a single layer 16-bit image to 8-bits, you will see something that looks exactly like the 16-bit image you started with. This gives me more latitude to deal with extreme scenes or work with files that I may accidentally underexpose. The human eye is more sensitive to shadows, and a logarithmic curve is applied to the RAW sensor data (not to TIF or other files after RAW conversion). If your source file is only available in 8-bits (such as a stock JPG), you should immediately convert the layered working document to 16-bits. We are making any minor errors or rounding error in the data more obvious. I have printed hundreds of very high-quality images that were uploaded to my vendor as 8-bit JPGs and the final images look amazing (exported from Lightroom with 90% quality and Adobe RGB color space). There arent that many situations where you would encounter a perfect gradient. I have several Saved presets that are my go to and i never use what ADOBE has listed, all my presets somehow had 16 bit to them! And opening a 12-bit file as 16-bits is really no different than opening an 8-bit JPG and then converting to 16-bits. But if you do run into banding (most likely if you get an 8-bit stock image), you can take the following steps to minimize it: Download the FREEluminosity masking panel . Inevitably, there are some incurable nerds who say its important to work in 16-bit mode for everything, but of course thats not true. But if we have enough bits, we have enough gray values to make what appears to be a perfectly smooth gradient from black to white. After all that discussion, it really comes down to a few simple rules. Remember that bits determine the number of increments relative to a range. RGB images with 8bits per channel (Bits/Channel or bpc) are sometimes called 24bit images (8 bits x 3 channels = 24 bits of data for each pixel). Off the top of my head, I can only think of one scenario where converting an 8-bit photo to 16-bit would be advantageous, and its not very common. Trouble is, you still only have 80 chairs, which you space out across the hall in a feeble attempt to "fill" the space. Conny's tip: When you have layers as smart objects, Photoshop allows you to set a different bit depth for the individual objects than the one of the source document. Be sure to enable/disable dithering in the gradient toolbar as best for your testing. This noise typically makes banding a little harder to see at a given bit-depth (ie, real world images dont typically show banding quite as easily as the smooth gradients Ive used above.). In other words, increasing the contrast in the image is like decreasing bit depth. Photoshop allows you to change the bit depth of an image in the "Image" menu, under the "Mode" sub-menu. Im sorry to say theres almost no benefit to this. You move a layer to position the content on the layer, like sliding a sheet of acetate in a stack. Banding is obvious/discrete jumps from one color or tone to the next (instead of a smooth gradient). Heres an example comparing a black to white gradient at different bit depths. How to change default bit depth. A 9-bit gradient is extremely faint (barely detectable) on both displays. 3. The problem you show with 8 bit docs not displaying correctly, on some systems, should be resolved in v23.3.1 released today. I dont know if Lightroom uses 15+1 or true 16-bit math internally, but I suspect the latter. When editing images for print, its important to understand and use the proper color depth to get the greatest range of tonal values. Most likely, you have a monitor with an sRGB color gamut. Can you change it in Photoshop? You should always use 16-bits when working with ProPhoto, which makes the minor waste of bit-depth a non-issue. This can start to make small gaps between values turn into large gaps. It is widely accepted that there are benefits to working in 16-bit rather than 8-bit mode for some repeat some editing tasks. 12-bits is definitely a reasonable choice. Lastly, add some noise to restore the appearance of grain lost due to blurring. When using Photoshops gradient tool, checking the dithering option creates the perception of 1 extra bit of detail. As you can see, there is tremendous shadow detail. If you have awide gamut (Adobe RGB) or P3 gamut monitor, then you have better gamut (with Adobe RGB expanding the blues/cyan/greens more than P3, and P3 expanding red/yellow/greens further than Adobe RGB). I wouldnt worry about it if you are using a 16-bit working space (you definitely do not want to throw away any bits if you are using an 8-bit working space, but you should never use 8-bits anyhow). Youll then want to save the file to retain any changes. Whenever I create a new file it automatically creates it in 16 bit depth, and I never think about it until I either go to use filter gallery or transfer my sketches to illustrator to refine and I cannot . Choose a bit depth for your image in Photoshop. The extra bits mostly only matter for extreme tonal corrections. However, not all printers are able to process high bit depths. If you were nervous about banding in the sky, you could convert to 16-bit before adding the vignette layer. But it seems your conference is going to be enormously popular, so you announce youre changing the venue to a huge hall thats big enough for 1600 people. To give a little more detail on my methods, I created an image that is 16,384 pixels wide which allows me exactly 1 pixel for every value in a 14-bit gradient. How did I test that? Anything else with detail makes it MUCH harder to see the difference in bit depth. I would gladly share the original PSB file, but it is over 20GB. To test the limits for my Nikon D850, I shot a series of exposures bracketed at 1 stop intervals using both 12 and 14-bit RAW capture with my D850 at base ISO under controlled lighting. Download our free iPad app at http://itunes.apple.com/us/app/video-training-courses-from/id418130423?mt=8More detail. Because Lightroom only allows +5 stops of exposure, I also adjusted the curve to bring in the top-right point to 80% for the both of the versions below. A wide gamut (ie Adobe RGB) monitor is also ideal. Images with 32 Bits/Channel are . So both sRGB and AdobeRGB already fail to capture the full range of colors that can be recreated on a monitor or printer today. Create dreamy backgrounds while . I created a software algorithm to generate my gradients in every bit depth from 1 to 14 on the image. Clear blue skies are probably the most likely. All Free Mockups is a participant in the Envato Affiliate Program, and as a Envato Affiliate, earns from qualified purchases. Next, select the Image tab from the menu bar at the top of the screen and find Mode. As a general rule, color depth, or bit depth, should be set to the 16-bit mode when making prints. Lets say you had shot in Jpeg mode (Jpegs are always 8-bit) and blown out the sky, so you wanted to add a gentle blue vignette layer to the white sky. There are massive feature limitations in the 32-bit space, workflow challenges, and the files are twice as big. I dont have a 16-bit camera to test. In Photoshop, this is represented as integers 0-255 (internally, this is binary 00000000-11111111 to the computer). So why doesnt Photoshop open a 12 or 14-bit RAW file as 12 or 14 bits? If you process for fine art black and white, then these numbers apply directly to you. There are a few different ways to change the bit depth of an image. Click the button at the bottom of the ACR screen to . First, make sure the mode is set to RGB Color. 16-bit images have 65,536 colors, and 32-bit images have 16,777,215 colors. One way is to use an image editing program like Photoshop. To start, open up your file in Photoshop. (Actually, not even raw data is true 16-bit in most cases. Lightroom was unable to get a proper white balance from the gray card, there is simply too much color noise at the pixel level in this file. I do critical work on a 27 Eizo (CG2730). The benefits of 16-bits are largely in the ability to manipulate the image without causing issues. Choose Percent from the Width drop down-menu and type 71 in the text box. Camera companies can claim any bit depth they want, it does not mean that you are getting better quality. Subsequent edits on 8-bit images will not degrade as badly if that math is performed in a 16-bit mode. What does it all mean, and what really matters? The result is that the bits used for shadows are lower quality (see DPReview for an in-depth discussion of the topic). No. 8-bit displays (which were similar to Indexed . However, if the vendor requires a JPG or you want to send a smaller file, you might be faced with questions about converting to 8-bits. An 8 bit image can display 16.7 million colors between the Red, Green, and Blue color channels. For more free Adobe design tutorials please visit out our main website. Youve already seen a theoretical example with the low-bit gradients above. Heres a better one lets say you are arranging a conference in a small conference room that seats 80 people. To see out the difference, consider the following simplified visual example: As you can see, increasing bit-depth reduces risk of banding by creating more increments, while expanding color space (wider gamut) enables the use of more extreme colors. What if you have a fancy camera that captures 16-bit RAW files should you be worried about Photoshops 15-bit quality? Bit Depth & Number of Colors. Clearly, this is massively underexposed throughout the image and about as extreme an example as you could ever imagine. So if you're image is at 16 bit RGB say a raw file, just convert it to 8 bit RGB. And so on. Note that if you want to create your own file in Photoshop, the gradient tool will create 8-bit gradients in 8-bit document mode (you can then convert the document to 16-bit mode and will still have an 8-bit gradient for testing/comparison). [Note that Im not saying these arent excellent cameras that produce better images, they probably are Im just saying that I dont think Photoshops 15+1 bit depth design is something to worry about when processing files from these cameras]. Another way to change the bit depth of an image is to convert it to a different file format. The one with the checkmark next to it is your current color depth. For example, an image with a color depth of 1 would only have two values: black and white. Before we compare the various options, lets first discuss what the naming means. In other words, there is noise in your image. Leave it as 8bit/channel in photoshop or lightroom and you're fine. ProPhoto is a good choice to keep all printable colors. Dont believe me? In other words, precision (the number of bits) and accuracy (the quality of the numbers stored with those bits) are not the same. And as discussed above, wider gamuts should be used with 16-bit files. In the popup, select a color mode you prefer and click OK to save the changes. However, it treats the 16th digit differently it is simply added to the value created from the first 15-digits. For the second, Colin Smith experiments with the Lens Blur Filter. If our scale is brightness from pure black to pure white, then the 4 values we get from a 2-bit number would include: black, dark midtones, light midtones, and white. Photoshop does actually use 16-bits per channel. Switching it to 16-bit fixes it. Color depth refers to the amount of tonal variation found in an image. Choose ProPhotoRGB. Every time we add another bit, the number of potential combinations doubles. If you have to send a JPG, it will be in 8-bits, but that shouldnt be a concern. Even if portions of your shadows are this underexposed, I cant see a scenario where you would fully correct them to a middle gray. The embedded image here is just an example, click here to see the full resolution image in the JPEG2000 format with bit depths up to 14-bits. Aside from P3 monitors, there are printers commercially available which exceed the AdobeRGB gamut as well (particularly in the cyans). If you print at home, you can just create a copy of your 16-bit working file and finalize it (flatten, sharpen, change color space if needed, etc). Thank you! Bit depth is one of those terms weve all run into, but very few photographers truly understand. In an 8-bit image, there are 256 colors. RGB Color, Grayscale, CMYK Color, Lab Color, and Multichannel modes can all be edited using 16 Bits/Channel in Photoshop. Be sure that you arent seeing false banding due to the way Photoshop manages layered files (see my previous post No, You Really Dont Have Banding for details on the issue and how to test for real banding). Instead, Ive posted a full-resolution JPEG2000 image (ie 16-bit; I do not see any differences between it and the original detail, even when processing it with extreme curves). I rarely would adjust RAW exposure out to +/-4 stops, but it can happen with extreme situations or portions of poor exposures. Copyright 2022 Adobe. This affects processing speed, memory usage, and hard drive storage. So bit-depth determines how the smallest changes you can make, relative to some range of values. Ok, thats still not a wonderful analogy, but I hope you see what Im getting at. Note that the image above is a black and white image. For a 16-bit file, it is unnecessary and increases the size of the saved file (assuming you are using compression to save your files). Even using extreme curves and other adjustments that go well beyond how I imagine anyone would edit these photos, I am not able to see any issues. Id almost say there is no banding at 9-bits. A 3-stop change in exposure is closer to only losing 2 bits. All Free Mockups also participates in affiliate programs with other sites. (In this case, the Mac menu appears on the left and the Windows one on the right.) The color cast starts at about 3 stops of underexposure (-3ev), is much more apparent at -4ev, and is a serious issue at -5 and -6. Or 12 to 16-bits ( RAW ) right tonal range for each one of your projects a printable (. Is relatively slight under extreme conditions comes down to a few extra bits of data are used to a.
