![]() ![]() You can do pretty awful things to an 8-bit file without causing problems that anybody would notice. The fact is, 8-bit is much safer than some people would have you believe. That’s a huge adjustment for not much banding. If you found yourself peering closely to try to notice that banding, you’re not alone. This time we can see the banding/graininess that can occur when editing 8-bit images: ![]() Still looks as clean as a whistle:īut for this one, I converted to 8-bit, THEN flattened. Remember, this is a gradient with an aggressive adjustment, but because it’s 16-bit, it’s very clean:įor this one, I flattened the layers first then converted to 8-bit. I’ll zoom in to 200% so we can see a bit clearer. If this file had been 8-bit, the banding would have been visible. Then I made a Levels adjustment layer, and made a very aggressive contrast adjustment to it. I’ll try to show you what I mean … Here’s a simple gradient I created in a 16-bit document: All benefit of 16-bit is discarded.Īdjustment layers must be committed to the image (by merging with the background layer) before conversion. If you convert your image to 8-bit while adjustment layers are still present and active, then you might as well have been working in 8-bit from the very beginning. The big thing I want to discuss right now is this: You must flatten your layers BEFORE converting to 8-bit. Some people say it’s important to sharpen while still in 16-bit, though I've never seen any evidence to support this. You could resize before flattening, for example. Now, the order of some of those steps is flexible. Your final steps for printing probably include: If you choose to edit your images in 16-bit mode, then of course you need to convert to 8-bit for printing at the end. ![]()
