Just started my latest hobby and invested in a Canon 40D + EF-S 17-85 IS USM lens. Would like to shoot in RAW and need to purchase some software. I have an Apple Mac at home and would welcome some advice on recommended software. Options are Adobe Photoshop or Elements for Mac or Apple Aperture 2 or anything you would care to recommend. I have a reasonable level of PC competency but no experience of editing software. Your advice greatly appreciated.
