Just a note to say, debating the term 'collage' was probably not the gist of this post. Lol. But, since someone brought it up, I've seen the word used for more than the definition stated. I use it for a group of photos I've placed together via Photoshop, sometimes overlapping or manipulated, in a design usually with some sort of text & border...as well as for some of my mixed media pieces when using texture, pattern, added items, drawings, glue & text. Either way, I'm sure most of us know exactly what Joseph meant & is talking about here! Again, I say, good luck...and have fun creating! You may come up with something new & unique with a definition to fit.
Warmly, Brooks
