I was considering a purchase of Photoshop Elements based on an article I read concerning the disadvantages of editing and saving photos in jpeg format (losslessness and lost pixels). The article recommended saving in tiff or psd format (Machome 11/05 pg 28) I use iPhoto for minor editing, just personal pictures. I was told by a salesman that iPhoto and Elements were extremely close in function. Any recommendations? Is iPhoto good enough or is Elements worth $90 (no way I'm spending $600 on Photoshop CS!!!)
