Fresh from my manual efforts to place myself in photos in 'Pretend been there', I took Detach for a spin. The idea is that you stabilise the shot (e.g. on a tripod or wall or shelf) and then shoot the background - I presumed, the plainer the better - and then step into the shot and let the auto-background-removal do its thing.
The huge problem here is that by stepping into the shot, you're changing the lighting of the background, adding shadows and shading, etc. In practice, this leads to slightly messy results, as you'll see:
An innovative wizard takes the user right through the creation process; (right) background removal is patchy at best in my tests - I tried various backgrounds and lighting.
You get several shots at a snapshot, until you're happy, though I never could get the ugly background-removal artefacts to disappear altogether.... (right) up to £3 of miscellaneous in-app purchases - fair enough, if I thought Detach worked well enough.
Detach is a free download in the Store, with some in-app purchases if you want to go further. To be honest, I preferred the manual approach in 'Pretend been there', though both techniques are flawed. Comments welcome.
