I've been shooting RAW since I got a camera capable of it. Until recently, though, I didn't realize what sort of versatility it offered me. I took this photo almost four years ago, and at first glance, it was an overall blah sort of picture.
I was going through one of my hard drives, just kind of exploring, when I came across this image. Once I opened it in Lightroom, I began to see possibilities. With just a few adjustments, I ended up with a very usable image.
Don't delete your photos, and give them another look from time to time. You might be surprised at what you have hidden in a RAW file.
