Hi All! I just got a digital camera - its a Canon Powershot A620. I have been a member of Caedes for over a year, and I have loved looking at all the beautiful shots people post. Anyways, I would like to start shooting photos to submit, butsince I am new at this, I don't know how to start. Is there software that I should get so that I can touch up my photos before posting them? And what are the best settings to use when taking pictures that you plan to use as desktop wallpaper? Thanks...Any help is very much appreciated!
