As I am not familiar with Photoshop ie don't know my way around the knobs and buttons..I was asking the 'how' question. So reframed:
I have taken two photos already one of a cheque and one of a person with their hands in a particular pose imagining they are holding a very large cardboard cheque in front of them. HOW (on PHOTOSHOP) do I take the photo of a cheque, and add it to a photo of the person so it looks like the person is holding a large cheque (from shoes to waist sized cheque)??
Thanks JJMack - will give it a go and let you know how I get on!
