Look at the EXIF data. Editing programs will leave information in the EXIF file. Of course, somebody can clean all the meta data and reinsert the original meta data.
This is easy to do using programs like jhead and EXIFTool. Otherwise, look for tell tale signs of editing. Question, what do you consider editing?
Is adjusting exposure, white balance, and cropping considered editing? Or, do you consider editing removing or adding things, like removing zits.
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.
