Photography. Controlling, and capturing light onto a an emulsion of silver salts at the back of the camera. Great hobby.
As for Photoshop / Lightroom, I don't own them, don't need them. When I need to make any mild post process edits to a digital image, I can use the completely free and open source Gimp software package. It has the software tools that I need and more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
