I had never really thought about removing the line honestly. I know in my videos as soon as I don't show the line for a while a bunch of people respond "I hope you aren't diving without a line"
Given how hard it was to remove some of the odd scratches from the dome on some shots, I am not sure my PS skills are up to removing it without it looking bad.
I do deliberately get a little off the line sometimes to get shots with no line but that doesn't always work.
Maybe I will play with it and see. What tools would you use ? I usually now use Lightroom and dont have to go into PS for anything (I only have Elements)
