Yes
Query..... When you shoot RAW , as i understand it ALL the date is retrieved within the file with no compression i.e. no losses. Are conditions like camera set white balance , contrast , sharpness etc applied to the raw image or are they ignored and need to be applied in the raw converter. I assume exposure is set even in raw .

You are right. no sharpness, contrast etc etc applied to image.
In the RAW converter you apply all those or none, and do them in photoshop...its your preference.
Nice to change the whitebalance in RAW converter though, if you had it wrong.
 
So on the 20d the parameter settings only apply to shooting in Jpeg etc ?
 
RAW is not an image, this is important, stop thinking of it as one. RAW is all the raw data that goes to make up an image including settings like white balance saved to a data file.
This info is used by a RAW converter program on your computer to create the image. The RAW converter lets you choose different parameters like a different white balance or different exposure before it processes the file into an image.

Corrected. You cannot change the actual exposure (shutter, aperture and iso) after shooting. :)
 
And it is ALWAYS better to get the exsposure correct in camera. RAW is great but correct exsposure is greater.

King.
 
Oh yes! The only thing I tend to not worry so much about is white balance...I leave it in auto MOST of the time and alter it in the RAW converter.
Exposure I do my very utmost to get it as near perfect as possible when taking the shot.

You can change the exposure 'compensation' by as much as 3 stops depending on what software you choose to use, It won't change what the camera saw but it's similar to push/pull development of film.

On the Olympus E500 you get to change it +-5.0 stops - really helps when you're an idiot like me, still forgetting that I'd not adjusted shutter speed BEFORE taking shot :)

Just starting to look at some photo's I got in Prague last week, took them all in RAW but now have no idea what to do apart from move a few sliders and see what it does :)
