Glyn Dewis goes through his process of retouching a creative grunge image from start to finish, showing how he uses Photoshop as well as plugins from Topaz and the Google Nik Collection. This video is great for some quick retouching tips which includes a simple lighting effect using paint brush and is some excellent inspiration for filters and effects to add to your images. As always, Dewis shows you how to work non destructively so that you are always able to go back and tweak your many filters and layers.
