I was assembling a collection of underwater images tonight and decided to see what Adobe Lightroom's 2012 processing engine would do to an old image I took at Roca Partida (Revillagigedos Islands, Mexico) back in 2006. Back then, I used Adobe Photoshop to quickly process the picture from raw to a 2000-pixel JPG image for screen viewing. Tonight, I pulled up the raw file in Adobe Lightroom, chose the 2012 processing engine, and did a few minor tweaks using the Develop module. WOW. It's like a different picture.
Have you had pictures take on new life when you've gone back and reprocessed old raw files using new image-processing software? If you haven't, it's time to get started!
