The RAW image does have any changes made to it at the point of capture regardless of camera settings, what happens is the camera "remembers" the camera settings you had at the time and these are stored within tha RAW file, when you open up the image in a RAW converter (depending on what you use) then some software can read the camera settings information from the RAW file and display the RAW file with those settings applied. You obviously then have then choice to keep them or not.

If understand you correctly the RAW image itself is not affected at all but the data is stored and can be used by some software so you can select amend these settings when editing in a RAW editor etc.

I'm sure Alan will confirm that, as coincidentally, I discovered it for myself last night while taking some test shots of the moon in RAW+jpeg (using the Pentax Silkypix utility). I was able to undo the jpeg settings embedded in the RAW file and then, try out different settings to compare with the original jpegs.fatspider wrote:

I can now see why so many people with the time and inclination to do post processing often shoot RAW.

You assume correctly, it applies to all camera settings such as colour, white balance, sharpness etc. The Raw software will simply read those settings and open up the RAW file with them as a starting point.

Thats is very useful to know, it had me very puzzled to start with, thanks-You assume correctly, it applies to all camera settings such as colour, white balance, sharpness etc. The Raw software will simply read those settings and open up the RAW file with them as a starting point.

I understood when shooting RAW images the in camera sharpness settings only affected JPEGS. I have just realised that if I shoot RAW only & adjust the camera sharpness settings the changes appear in the RAW image properties. eg
If camera is set to a small amount of extra sharpening as well as "Fine sharpeness 2" in properties it shows as "hard" sharpness.
However if I set fine sharpeness to off/normal and reduce the sharpness slider downwards a little the photo RAW properties show sharpness as "SOFT".
I havent as yet studied the images closely to see if actual image sharpness is affected but I will if I get the chance.
Advice, views & comments appreciated
