new rMBP13 owner here- i want to purchase a good photo editing program- I just was planning on downloading the Aperture program from the App store but after reading several of the current reviews I thought I would see if anyone can offer me some direction. I like to import my photos in RAW from my camera and currently have a very old version of Photoshop on my five year old PC which allows for adjusting everything really easy with slider bars (exposure, temperature, etc.) anyone recommend me a version of photoshop or should I go with Aperture- thanks
