The image below is a combination of photos with filter 'neon glow' applied and images above combined in layers with opacity approximately 50/50
The following images had filter 'cutout' applied to simplify the images then varying degrees of opacity of 'childs' prespective
Although altering opacity in Photoshop gives an indication of how physical layers might work, I think I'm going to return to previous studies in layering images printed on organza over images printed on cotton. This gives a subtler (and more 3d ) effect as can slightly offset the images.
I was just thinking what a difference being able to observe the Henry Moore sculptures at RBGKew has made to my thinking. I've been used to interpreting paintings and sketches - observing and interpreting 3D sculptures has been far more challenging. And exciting!
