I have been trying to figure out a way to remove the smudges and dirt from the bottom of pictures. Particularly where people have walked on the white background, and left footprints. I attached an example for a better idea. The simple solution would be to put down a clean piece of backdrop, but time constraints don't allow that. Instead, my boss and I have been editing hundreds of these pictures individually using the typical tools: spot healing brush tool, healing brush tool, clone stamp tool. We change the opacity, flow and hardness for each tool depending on the area we are trying to clean up. However, I feel that this is a very inefficient method, and would be so grateful to hear from anyone who may have a reasonable suggestion to speed up the process. Once these images are printed it is essential that the floor be completely clear, because otherwise it will show flaws and we will have to go back to editing and spend more on additional prints. Thank you!
