Thanks for stopping by.
Now, today’s post is kind of a response to a few questions I’ve had about retouching in 8 Bit or 16 Bit.
Ok so here’s the thing…
Up until the last few months I was indeed retouching images in 8 Bit and there were lots of reasons for this…one being file size, especially now shooting with a Nikon D800. Now though everything has been upgraded and anything that hasn’t been is just about to be so things have changed and I do edit in 16 Bit; but…speed isn’t THE reason for the change.
I’m certainly not going to attempt to get all technical here but in it’s simplest terms there’s much more information in a 16 Bit image or to put it another way, you can ‘push’ an image that much more.
For example let’s take this Retouching Technique commonly used in Beauty Retouching called Frequency Separation; on the left hand side you can see the 16 Bit image and on the right hand side the 8 Bit image.
Now now other retouching has been done; all that’s been done is to have prepared each image using the steps in the Frequency Separation Technique and already there’s a difference (hopefully you can see it on your screen) i.e. the 8 Bit image has banding appearing on the dark grey background whereas the 16 Bit image doesn’t.
So in it’s simplest terms…16 Bit images give us a lot more information to work with or to put it another way…they can take a lot more punishment 🙂
If you haven’t seen the Frequency Separation Technique then be sure to check out this video tutorial that I recorded:
