There's more than one way....
I was kind of perplexed recently by a client that had taken photos in one setting, but then decided that backdrops may have been better. I was thinking "Wow, now I have to re-do the entire shoot!" Then I remembered my software. There are easy ways to remove people from a photo and place them on a desired background. I immediately began to find desirable digital backdrops and went to work experimenting. I was amazed at the quality of the photo after using the software to create the event I was after.
After a little work and some positive feedback, I decided to work with other pictures and backgrounds to see just how amazing they could turn out. Granted, some photos will make you wish you had just done the extra photo shoot, but with a little perseverance, they come out just fine.
