And following on from my comprehensive title... I need to crop photos, and edit them in such ways as: Adding lines/arrows Blur out certain features (car number plates, for example) Add text in boxes Straighten pics out. I'm not into making photos look sepia or negative or the like. I'm looking for a Mac application that can let me do the above things, but also one that might wow me and let me do things that I think are really cool and useful. Like perhaps stitch photos together? I have tried shift/cmd/4 to get a snapshot then open the result in Preview, but I don't think much of the interface or what it appears to offer. Any ideas out there, please?
