I decided to drop the double exposure idea because it want to keep it more simple. Just having portraits with the subjects own handwriting overlaid is going to work really well without having to add to it.
If I complete all the 100 portraits with handwriting overlaid and I have time I might look at adding some double exposure in between a few slides. But it will all depend on how long it takes me to create the 100 images, and turn them into a slide show.
I didnt want to make too much work for myself incase I run out of time.
– Although double exposure images throughout could add some texture to the whole slide show.
