Here we are now in May 2007, and it’s update time again. This time it’s Photoshop CS3, significantly the tenth version of the program, and the most ambitious to date. It’s also somewhat larger than that original version 1.0, since it comes on a DVD and requires 1.5GB of disk space for installation. Version 10.0 improves many existing features, adds some surprising new ones, and also greatly improves the appearance of the user interface, something which has needed doing since version 7.0.
