Adobe Camera Raw For Canon 60d Windows Media
RAW is not available in the 'Green Box' (Full Auto) mode. It might be restricted in some of the other highly automated modes, too. I dunno, I only ever use Av, Tv, M and P. And I nearly always shoot RAW. I applaud using RAW. It allows for more changes later, if you wish to do so.
It does require post-processiing, but that's just part of shooting digitally, as far as I'm concerned. All digital cameras capture RAW initially. Kirby return to dreamland iso ntsc or pal. When the camera is set to JPEG, it immediactly converts the RAW to a JPEG according to the various settings and a great deal of the captured data is thrown away in the process. JPEG files offer much less opportunity to go back and correct things such as white balance, sharpness, contrast, exposure, saturation and more.
Plus RAW files are the full 14 bit the camera is capable of (interprolated as 16 bit in post-processing software), with literally millions of shades of colors. JPEGs are 8 bit, with thousands of shades. That's one reason RAW files are so much larger than JPEGs of the same image. Granted, a lot of uses only call for JPEGs. Which are quick and easy to make in post-processing, while keeping the original full resolution RAW file if you wish, for any future revisions or different treatments of the image you might want to make. I do most post-processing in 16 bit mode, then doesn rez the image to whatever size and format is needed for its final purpose. I'd much rather have the flexibility to go back and make minor changes and keep the image as a 16 bit file if I wish, than only have an 8 bit JPEG at the end of the day.
So I only shoot JPEGs when I absolutely have to have an image immediately or if I'm short on memory cards (but I have more than 20 memory cards with over 200GB of storage space, so that's unlikely to happen). *********** Alan Myers San Jose, Calif., USA 'Walk softly and carry a big lens.' : 5DII, 7D(x2), 50D(x3), some other cameras, various lenses & accessories &.

I'll try to describe the difference. The sensor is covered with light sensitive 'photo sites' which ultimately translate into an image -- but it's a lot of information. The file-sizes would be large.
When files are saved as JPEGs, the algorithm can substantially reduce the size of the file. But to do so, it has to give up some of the original data. The algoirthm plays on weaknesses in the way the human eye works. Your eye is more sensitive to subtle changes in brightness than it is to subtle changes in hue. So the JPEG algorithm saves a LOT of space simply by taking hues which are extremely similar (and nearby) and rather than storing each one as it's unique color, it combines them (or 'flattens' them) into the SAME color hue.
This means the original color is now lost. But your eye probably would never have noticed the difference anyway. Here's a fun test if you'd like to see how sensitive your eyes are (or are not) to subtle differences in hue: If you are completely satisified with the image the way it comes out of the camera, then JPEG is for you. If, on the other hand, you want to adjust the image. Now you may have some problems. Suppose I take a photograph of a bride and groom. The groom is wearing a black tuxedo.
The bride is wearing a white wedding dress. If the image is slightly underexposed, the subtle differences in the dark tonality of the tuxedo will be lost and the JPEG algorithm will flaten everything to just plain 'black' and the tuxedo will loose detail. If I slightly over-expose the image, the subtle differences in the white tonality of the wedding dress may be lost. Instead of seeing a beautiful and intricate patterns in the dress.
I may just see 'flat white' and may not be able to recover the detail. If, on the other hand, I shot the image and saved it as a RAW file, then the subtle differences from pixel to pixel will be retained (no matter how subtle). There will be no loss of original data. The image will be significantly larger. But everything will be there. Now when I start to adjust the levels in the image, the subtle differences that weren't so noticeable when the image was originally created can be enhanced and the detail can be revealed.
