![]() If you open them as 8-bit, you’ll be losing a lot of the potential because the extra information they collected is now compressed. You can look for this information in your manual or by doing a simple Google search. The images taken in RAW mode are 12 or 14 bits (this will depend on the camera). On the plus side, you’ll have all the tools from Photoshop available, and the file size will be within a normal range.ġ6-bit mode is where you’d want to edit your RAW images. One of the most noticeable issues you encounter in this situation is the color banding that appears in grading areas that should look smooth. If you need to make changes – for example, correcting a very under (or over) exposed image – then you’ll start to lose quality. Usually, the 8 bit vs 16 bit is hard to see with the naked eye. ![]() This is OK in many cases as the human eye can’t actually see all the 16.7 million colors these types of images have. However, you can convert JPEG to RAW with the help of specialized software. When you open them in Photoshop or any other editing software, they’ll stay in 8-bit mode.Įven if you change the workspace to 16 or 32-bit mode, there won’t be any extra information to work with. Let’s see what the difference is and when you should use each one.Īs I mentioned before, JPEG photos are 8-bit images. In Photoshop, you can choose to work in 8-bit, 16-bit, or 32-bit and this will determine how extreme you can make your edits before you lose quality or get artifacts like banding. Then, you have to consider how you want to edit your images. So, that’s the first thing that’s influenced by bit depth. When you’re photographing, you can choose between shooting in JPEG, which generates 8-bit images, or RAW, which will give you images from 12 to 14 bits depending on the camera that you’re using. So, what does that mean to you in real-life photography? If you then multiply it by three channels… well, you get the idea. That means 281 trillion colors.Ī 32-bit image has 4294967296 tonal values, and let me tell you, I don’t even know how to read that. That equals 16.7 million colors.Ī 16-bit image has 65,536 tonal values in the same three channels. Instead, it can hold 256 tonal values in three different channels (red, green, and blue). So, an 8-bit image doesn’t have 8 colors. When you add more information to it, the color depth grows exponentially. ![]() There aren’t any tonal values in between and there are no other colors. Now, a one-bit image can only be black and white because 1 bit can only be black if it’s a 1 or white if it’s a 0. Digital information is stored as either 1s or 0s.
