This post is for up-and-coming photogs that still ask themselves the question...

First off, what is RAW?
RAW is a file format that captures all image data recorded by the sensor when you take a photo. When shooting in a format like JPEG image information is compressed and lots of that information is lost. Because no information is compressed with RAW you’re able to "tweek/correct" poorly exposed files in post-production, and ultimately produce a higher quality image, than you would, if tried to correct it from a JPG type file.

Here's a perfect example, of a not-so-perfect image of the father of the bride (and good friend) and I, at a recent wedding in Florida. For whatever reason, this shot was grossly under-exposed. Whether conditions were difficult, the flash batteries were dying, or you're simply having an off day, etc... shit happens! But with the magic of Camera raw and a few post-processing corrections, the photo is still rendered usable.
The downsides of shooting RAW, is yes, the files take up a considerable amount of space, need to be post-processed (longer to edit), but in the end, you'll be much happier with the overall results.
Enjoy!
