For the layers experiments I decided to experiment with different ideas, for example I tried the gradient solid back ground and then I tried a patterned background for one of the pictures and then I included a inverted picture on a patterned background.
For this picture above I have experimented with layers and I tried using the patterned background instead of using a plain one, In my opinion I would say that I prefer the patterned version gives a contrast and just having a solid colour for the background.
This Image I first used the invert tool to create the image a different colour and then I decided to use the patterned background to shift the focus on the image and the background.
This Picture is my favorite as the picture behind is very simple and it is abstract, then for the layers I decided to use the gradient version instead of one colour in my opinion I think this is very effective solution as the darker shadows of the picture contrast with the colours.
