Self portrait ideas Mapping 2013 on Behance Use a process like this for "identity/self-concept" activity about skin color/shade/tone/palette. Put vertical photo strip of every child together on a couple images to make a collective face.
Paint-over-Photo Collage A photo has been printed, then pastel paint was painted over the face. I like the simplicity of this collage, but it still looks really nice. If I were to do this form, I would do it as a series.
This example of photomontage works well because it is visually interesting and has a lot of contrast. The photo of the woman is in black and white while the photo of the plant is shown in color this contrast makes the image stand out more.
Take a mug shot style photo. Rip out the eyes rip out the mouth rip it in half shred it into as many pieces as possible and collage them do the thing in the pin out the face and stick it back upside down
