Right now, you can get Lightroom 3 from Amazon for $179.99. For those unaware, Lightroom 3 is a RAW image processing program that makes life working with RAW files so much easier. It also carries a hefty retail price of $300, so getting it for $180 is a real bargain.
If I could only have one photo editing program, this would be it. Here’s the link to the Amazon.com deal page.
