Strange graduations in colour known as posterization and other artifacting can sometimes appear, resulting in a very unnatural look. The difference between the two can at times become apparent when making more considerable changes to your images in post. When considering the fact that our eyes can only differentiate around 10 million colours, working in 16 Bit may seem valueless. When combined together, 8 Bit gives us approximately 16,800,00 different potential colours, whereas 16 Bit provides literally trillions of different colours. Compare that with 64,536 of each when working in 16 Bit. Let me provide a brief explanation.Ī "Bit" is a computer term relating to data storage. Described here as "Bits Per Channel", what exactly does that mean in practical terms? Well, more "Bits" = more potential colours available to us. When working in 8 Bit, we have available to us 256 different values of Red, Green and Blue. This often overlooked setting can potentially make a noticeable difference in your post processing. It's always best to start with a full resolution master file that you can downsize and output at lower resolutions for web later on. This is the industry standard for both printing and stock photography. Image resizing should be done later on, once you have saved a master file in Photoshop. This will retain your camera's native resolution. This is commonly set to sRGB, which is a far more restrictive colour space, used by web browsers to display images online. This is a wide gamut colour space that will allow the full range of colours that your camera captures to be retained and put to good use as you go about editing your images. My recommendations are as follows:Įnsure your colour space is set to "Adobe RGB" This will open up a menu with lots of different options. When you open an image into Adobe Camera Raw, click anywhere along the text you see highlighted above. Accessing your Workflow Options is very simple.
