For me, double exposures or better multiple exposures wether with myself or someone else are part of my photographic work. If ou send a roll of film to someone, it is always surprising, what comes back. Also if I double myself there is always the chance of mistakes. But for me it is clear to not just use double as effect and digitally put two photos actively on top of each other.
But what I do is use dubble to randomly create digital dubbles (without the „o“ and with double „b“) with people using the app, too. It also allows you to re-dubble a photo, so the same layer can appear as often as you want or as often until you are satisfied with the result. The nice thing about it is that it makes square photos and, again, that your duble partners are chosen randomly. And for people who already have an idea of how a double works, dubble is easy to use by choosing „good“ singles to upload to get the most out of it.
The question is now: is it just a nice effect or can you work with it as artist?
Here now a selection of some dubbles I made.
