I have been working with my images from my D5100 in lightroom. I'm shooting in raw and adjusting for white balance and exposure in lightroom. I wanted to play a bit with other aspects of processing (e.g., smoothing and or removing background items, etc.), but wasn't ready to spend as much as they ask for PhotoShop or PSE. I decided for $15, I'd try Pixelmator. I'm just starting to learn to use it, but thought I'd see if anyone has experience with it now to get tips, etc...
