Step-by-step tutorial for altering colours in photographs using Colour Overlays in Photoshop. This tutorial was originally designed for an AS Level class in Graphics. The one-sided worksheet provides a clear tutorial for learners in using Adobe Photoshop to change colours in photographs. An example of jam jars was used to explain the technique, to illustrate that the original red hue of strawberry jam can be altered in Photoshop to depict differences in flavours, eg. apricot, blueberry, etc. This easy step-by-step tutorial is great for anybody wishing to improve their Photoshop skills.
