Trolling through my image library, I found the picture above and I was about to throw it out, but decided to try an experiment first.
Some background: A lot of people believe that a JPEG image is etched in stone and can't be manipulated like a raw image. They also believe that Adobe Camera Raw is for raw files only.
Wrong on both counts.
You can open image files such as JPEG and TIFF in Adobe Camera Raw and do most of what you can do with a raw file. For JPEGs and TIFF files, you don't even need the latest version of Camera Raw. I'm using version 6.7.
I've written about this in previous posts, but it's worth repeating, especially with a really good example to illustrate the point.
The pictures below show the process step by step.
Some technical notes: The original picture was shot with a Panasonic DMC-LF1. The post processing was done with Adobe Camera Raw 6.7 and LightZone 3.
