Job Description

I have apx. 100-150 pictures that have a grey background that I want to change to white. I estimate the project to be a 2-4 hour job.

There are two types of pictures.
1) Pictures of Frames - the background needs to change from gray to white but the shadow still needs to be maintained.
2) Pictures of sides of lenses.

This shows the gray background:
