A lot of effort. Lightroom as a tool to adjust is an excellent program and I use it to,well,adjust images.Like theseOh seriously!
So he only shave once a week and spend the time in between doing this?
My good friend @stillshunter is into photography - I’m sure he could do better![]()


Photoshop can be used to adjust,but I like to use it to manipulate images



To use LR,PS and Nik to adjust an image is taking a fair bit of time to get a result that any single one of the programs can do.But,the old YMMV comes in to play here.
ETA: That repaired/colourised image was the first one I ever did,and I have advanced a little since then.My parents btw.
