1. I learnt how to use blend modes correctly to be able to manipulate the colours and textures of an image. This can help me to make an image more realistic by helping the photoshopped images to be able to match their lighting.
2. I learnt how to make use of images in order to apply textures to surfaces. This can help me to be able to photoshop images that are more realistic and not have smooth and plastic-like surfaces.
3. I learnt about how clipping layers can be used to help one to colour certain parts of the layer. This can help to create minimal obstruction and mess when editing an image, allowing the photoshopping process to be shorter.
