First of all what is RAW?
Simply it is the unprocessed, uncompressed information for each photo. It takes up a lot more space to store all that data, but gives you a higher quality image in return.
What does that mean?
More time in post processing and editing for the photographer. Instead of just running the images through Photoshop, I have to put each image through additional software and process each file.
Why shot in RAW if it means more time to edit later?
Good question. The last two years that I have been shooting in RAW I have seen my photos improve. I can confidently shoot in manual mode, letting me tweak the settings just how I want them, instead of letting the camera do most of the thinking. This helps me learn what I like best and more importantly - what I don't like.
The great thing about RAW is if I do make a mistake, I can adjust it later without compromising the quality of the images.
Since every post is better with an image here is an example:
The left is the RAW file, right is the tweaks I made before processing the RAW file into a JPEG.
The bottom image is the final edit after running the JPEG thru Photoshop.
F2.8 1/4000 ISO 400 50mm
That is as technical as I get. I hope I didn't bore you with details!
Have a great day!
