About this tutorial

It’s all too easy to accept the flaws in an image file and go along with the gratification of improving an image that’s ‘broken’ from the outset. But there’s often a chance of getting a better input to work with. Sometimes you just have to ask for it! In this Gry Garness Photoshop tutorial, Judging The Input, Gry presents an overview of things to look for in a capture so that you can assess and fix problems from the start and achieve the optimal quality.

Unless you’re very aware, you can be caught out by file size and here we have a rough guide to the 8-bit sizes you’ll need for print. Here’s the truth about sharpness, focus and what sharpening actually does. What is a good exposure? Well that may depend on the capture format. Why is color gamut so important? Why does banding happen and how can we overcome the problem? Is noise always bad? The questions are answered in this video tutorial on image input which is a MUST for Photoshop photo retouchers on every level.
