Color Temperature.....

[neuroanatomist]

If you shoot raw, there is no difference. For JPEG it can be a huge difference.

Bingo. For many people who shoot RAW, this is one if not the major advantage - with RAW you can adjust the white balance in post-processing with no IQ penalty. If you shoot JPG, you degrade the IQ by changing the color temperature in post.

Is it a sliding scale, good---->bad, going Raw--->sRaw1---->sRaw2----->large jpeg?

No, there's an abrupt decrement between sRAW2 and large/fine JPG. The sRAW formats are smaller files (both in resolution and in megabytes) but preserve the editing advantages of RAW (penalty-free WB changes being one of them). You can read more about sRAW here.

My thanks too. I found it informative and helpful.

Canon's page about sRAW doesn't really describe what it is. In reality, sRAW is actually a high quality 15-bit JPEG. In other words, the only difference between JPEG and sRAW is that the sRAW is 15-bit linear and JPEG is 8-bit log. The compression is the same as JPEG at the highest quality setting (where it only throws away half of the color information).


This is very different from true RAW, because it's already demosaic'ed -- all your raw converter can do is display the file (like a JPEG) -- it can't apply it's own demosaic engine. Personally, one thing I dislike about Canon's demosaic is that it causes mazing artifacts when noise is high, so I use other raw converters. But if I were to use sRAW, the artifacts would appear even with other raw converters.


That's not to say you shouldn't use sRAW. Most of the time, going from 15-bit JPEG ("sRAW") to 8-bit JPEG is worse than losing the resolution.
