Overlaying images to create the shape X might look interesting and unusual. I don't want to take pictures of the shape in a literal way.
The image below is the kind of style of design I am wanting to achieve. I would like to use geometric shapes to create an unusual visual pattern.
I think black and white photos would work well for what I have in mind. I would like to use this style in my own designs.
I think black and white might look quite effective on my postcards, however with maybe one or two colours it could work to highlight certain details to add impact.
I like the idea of laying up photos to create a geometric style design.
