I'm trying to figure out what software to get and start using for post processing, being new to the whole digital photography thing. For starters, I use the Mac, and was just able to get a base model 2010 Mac Pro. I've given it 12GB RAM, a 256GB SSD for the OS (Mountain Lion 10.8) and apps, and a 2TB drive for the user space. As for what software to use, I was looking for advice and people's option. I can say right now that unless someone gives me a copy, Photoshop is out of my budget, so for now I'll be using a combination of The Gimp and GraphicConverter depending on what I need to do. What I'd really like is thoughts on RAW software. My Panasonic GF5 came with SILKYPIX and my Mac has iPhoto from iLife '11. I'm already planning on updating to the latest version of iPhoto to manage my photo library (For photos after PP so that my wife can easily browse through them and print or email as she wants, like mothers do.). And I really don't want a Aperture vs Lightroom debate, just why you use what you do. I'm leaning to Aperture because it is more integrated with the OS and iPhoto, and costs less. I've also learned of RawTherapee, and wanted to know if anyone uses it and what they think (Like SILKYPIX, the price is perfect, free.). Anywho, the basic short of it is, advice (and why) on which should I pick, SILKYPIX, RawTherapee, Aperture, or Lightroom; with the knowledge that I use a Mac and want to use iPhoto, The Gimp, and GraphicConverter. Thanks ahead for your thoughts and time.
