Ya you heard me write, Till anow we all were obessed with calibration of Monitor only but I recently came to realize need of calibrating camera like mine ( power shot a40) that have no profile of their own.
Any body can guide me in that
BTW check this link , a whole web site dedicated to just calibration Calibration web Site

Great link to look deeper into. From what I am aware of, alot of cameras cannot be calibrated. I have heard of being able to PROFILE cameras with different (AdobeRB, sRGB, etc.) profiles. Calibrating may be a tougher thing to do (void warrantys, maybe?) and or impossible in some instances.

Well, we all calibrate our cameras when we set the white balance :)

May be i used the wrong word, calibrate, Well i read this word on net so i used.
Word should be Profiled.
It means creating a custom icc profile for camera like mine, not ures . Camera like 10d, d100, 300d must be having their icc profile, mine doesnt have

White balance preset in most cameras is inadequate to cover the wide range of light temperatures likely to be encountered.
Manually setting the white balance is a far better practice but is not always possible, especially when quick action is necessary
to get the shot. Compensating the white balance in post-processing is always an option, that is what your camera does for you
when you set the white balance. Most image processing software allows adjustment of color balance that can be used effectively to
correct images that do not represent the actual shooting conditions. Post processing requires some practice to achieve good results.
Some photographers simply ignore white balance settings in the camera and process all images to achieve the result they feel is most
pleasing (not necessarily accurate!). But the bottom line is always the image quality. With film we had little option but to
select lighting and filters to accomplish the 'look' we desired. Now we have great latitude with our 'digital darkroom' to get
almost any result we wish to present. My advice: Use the white balance when color accuracy is required and use your image processing
software when an artistic effect is desired. |

This is not about white balance. Its is about creating an custom icc profile like we do of Monitor after calibration.
I am not talking about setting wb

Well calibration for a camera would be a bit difficult I'm thinking. You'd need a way to tell the camera that "this is red", "this is blue" and "this is green". This is easy with a monitor because you just strap a sensor to it, and then you adjust until the sensor says you're at "red", "green", and "blue". How the camera's sensor interperates the light is part of it's own built-in hardware/firmware. So it would take a modification in one of those two areas to get a profile. Not easy to do on the consumer side, unless it was designed to be.
