Separating a double exposure


Recommended Posts

OK...I do not shoot much digital, certainly not enough to warrant

PS. I spend 12 hours a day in front of the computer for work. My

darkroom is a vacation in comparison to having to use the computer

for photo's as well.

 

But, in this case, I need help from the photo techies and I would

appreciate some assistance. I recently shot a wedding (informally)

and had a problem with a frame not advancing which resulted in a

double exposure. The bride and groom really liked the shot and would

like it if I could get it 'fixed'. My question is this: Is it

possible, using PS or any other software to separate the exposures by

density? Has anyone ever had to work on a similar problem before?

I don't think it's possible. If you were a master retoucher and had a lot of time, you could

fix most of the image, but the two superimposed figures to the left, the woman and man,

would be extremely difficult to work with. She comes in strong and obliterates his

shoulder and body, and he cuts through her face. Tough one. Next time hide the outtakes.

What follows may not be of direct interest to you, but I think other people may be interested. All I know about this topic is what I just gleaned from CiteSeer. It seems that the technology for doing this is still in its infancy. If so, this is a fantastic research topic (new graduate students, take heed!)
