Default RAW vs TIFF?

Hi everyone,

Can someone explain to me the difference between RAW and TIFF files? The way I see it, both are uncompressed and RAW smaller and is easier to manipulate afterwards, so why use TIFF?

Thanks
Joel

Because most viewers and photo manipulation software do not work with the RAW image. It must be converted to TIFF or another format first. Also, RAW is not a standard like TIFF, JPG, GIF, etc. It varies amongst camera manufacturers.

OHenry is correct: Tiff is a universal format while RAW is not!

Joel, just in case you don't get mislead here, they aren't saying you shouldn't use raw format. It's that you shouldn't save your final, edited version in that format. Using a universal format such as TIF is best. Of course, Photoshop's PSD format is unlikely to disappear anytime soon, but not all programs can use it or "see" it.

Raw has its distinct advantages, particularly for those of us who are control freaks. (Who, me?) It represents only the information the camera has collected, not what the camera has decided to do with it once it has the info in its grubby little paws. Sharpening and increasing color saturation are two things most cameras do. Raw format gives us the chance to decide for ourselves how much or how little of these changes we want made.

At best, it will be the next three standards: Fovean, Sony RGBE, and Bayer.

Standard or not I'd take RAW format over TIFF any day.

Right off the bat RAW file sizes are smaller so more photos can fit on your camera, eg. 5MP RAW = 8MB and 5MP TIFF = 30MB. TIFF is 8bit (24bit on the computer) whereas RAW is 12bit (36bit on the computer). RAW can always be converted to TIFF or JPG later so I personally see no reason to have TIFF as an option on the camera.

"Personally" is, of course, the key word here. I agree with you, but the huge number of newcomers to digital cameras and editors might have a tough time dealing with everything they must deal with and then have raw format dumped on top of their heads.
