Getting a RAW Deal

I’m constantly asked by novice landscape shooters whether I shoot in RAW or I shoot in JPEG format with my camera. I always shoot in RAW when doing landscape work and portrait photography. The only time I record images in JPEG is at action events where I’m rattling off a lot of shots at high speed and can’t afford to burn through my memory cards too quickly using larger files.

A RAW file from my Canon EOS 5D contains 4096 levels of tonality between pure black and pure white. A JPEG file can only contain a maximum of 256 tones between black and white. That’s all the camera keeps when packaging each JPEG.¬† Whenever you have to make extreme exposure adjustments to a JPEG image, those missing tonal values come back to haunt you. A sky blown out to pure white remains so. An image shot in RAW will have extra information there — information that you can’t necessarily see — but that can be tweaked back out of the file.

Here’s a picture from this morning. It was a relatively high contrast scene as the clouds behind the barn were back lit by the sun:

Barn Unaltered

If that had been shot as a JPEG, it would have been a throwaway image as that blown out sky would not have been recoverable. However, since I always record in RAW, I was able to produce the following after some tweaking in Photoshop:

Barn adjusted

Sure, RAW files are big and bulky, but that’s because they’re chock-a-block full of extra tonal levels, image information that can either make or break an photo you’re working on. Storage is cheap, but good pictures are priceless.¬†Shoot in RAW from now on. (If your current camera doesn’t allow you to save in RAW format, update your list for Santa.)
