PSD colouring files really have two clear uses – the first of which is time-saving. If you can achieve the required adjustments to your image just by inserting a pre-made group of adjustment layers, the time-saving factor can be enormous – especially if you are working with a lot of images requiring a similar effect.
The second use of PSD colouring files is to learn from them. Whatever your Photoshop skill level, there are always more tricks, tips and techniques to learn! PSD files are a great way of learning how to achieve photo effects, and it is easier to see the process than with actions.
Whatever your reason for using PSD colouring files, it is useful to have some in your PS resources library.
For this showcase I have applied the files to different images – just to show they can work on other images as the photograph the author shows is usually the one the file was built around.
