You might be getting the idea by now if you are following my posts that I enjoy blending one or more photographs to produce abstracts. I used to do this in camera on slides, either using a multiple exposure technique or by taking the film out of the slide mounts and sandwiching two or three slides in a new mount, then scanning it. Digital cameras (at least not mine) don’t let you do this kind of thing in camera yet, so Photoshop is my best friend in this case. There are so many post-processing options with Photoshop or similar photo processing programs — the sky’s the limit as to what you can do.
