I'm buying a new iMAC this weekend and I had a few questions regarding photo editing software. I am currently on a PC using Digital Photo Pro/Adobe Bridge/Photoshop 3. I download my images into Photo Pro/Bridge and then use PS only when necessary. I do most of my editing with Photo Pro on my RAW files on in Bridge when I shoot a ton of files(weddings)and want to work faster. I'm planning to get rid of Photo Pro because I need an upgrade, so I've been toying with the idea of switching to Lightroom instead of Photo Pro/Bridge but decided to buy an iMac for long term usability/stability going forward. My question is: Will it be better for me to purchase Aperture 3 for my new Mac or should I buy Lightroom for my Mac. Any body with experience in this operating softwares your input would be greatly appreciated. Thanks in advance!
