Hello, I have an inquiry, I want to work with a photo like this which I will either link or post and I cant seem to do it.

Id love to cut it out so I can put in on another photo but its to the point that its just too dark to do anything.

If you have any techniques or ideas on what I should do please let me know!

Here is the Photo.
