From what I know adobe try and squeeze as much as they can into software packages and that sometimes makes it confusing. If you are someone who uses picture editing a lot then I would just use element, because it's more for pictures with any format available to you and it's quite easy to use and understand for those who don't have wizardry skills on computers xD. Download both at the adobe website and see how they can help you, and make up your choice after end results.
Overall opinion, Adobe Photoshop element9.
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.
