RAW why is this desireable?
 
ok a really basic newbee question... why is RAW something people want? Is it because you then don't let the camera compress it or process it so you can decide how it looks?
I just want to understand.
thanks in advance.

That's exactly it.

Your thought is exactly it, it is good if you are into post production, and enjoy the after shooting aspect of photography. You can do way more with RAW in post production then with jpeg.

For lazy folks like myself. I tend to shoot only jpeg as I let the camera do the processing and compression. Also if you travel allot, Raw eats up allot of memory, so it can be limiting on the number of shots you can take with RAW vs jpeg on a long trip.

also it gives you about a stop to stop n a half latitude to get back clipped highlights and dark shadows.

Most RAW converters not only allow you more exposure latitude, but also are able to correct white balance, and preserve more fine picture detail than the camera algorithms. The down side, as mentioned, is larger file sizes and more time taken in post processing.

sorry what does this mean in English? what is stop to stop n a half and clipped highlights
Just trying to learn..

Clipped highlights simply means overexposure, but in some cases, if it is not too overexposed, the RAW file will have enough greater capacity, due to using 12 or 14 bits vs the 8 bits per color channel in jpeg, to allow you to adjust setting in the raw converter to recover the highlight detail that would be lost if the camera created the jpeg. Stops, are measures of light, same thing basically as EV.

Read this article for a primer.

There is another advantage. When I first started out on DSLR 6 years ago I became convinced that shooting RAW was a good idea. I'm very glad I did, as the RAW converters of today are much better than they were back then. I can now revisit shots I took 6 years ago and get a better image from them than I did back in 2004.

I like to shoot RAW when there isn't enough time to make sure I am getting the exposure and/or white balance right. Fast changing special occasions with the grand kids in uneven/mixed lighting is a good example. As several folks have said, RAW allows more chances to fix errors.

TCav Feb 8, 2010 8:38 AM

Yes, if you only have one chance to get it right, shoot RAW. If things weren't ideal when you took the shot, you can take advantage of more wiggle room when post processing a RAW image than a JPEG image.
