Building Noise-Profiles - general question
Posted: Tue Dec 23, 2003 3:00 pm
As I understand, digital camera noise depends in first case on the CCD- (or CMOS) Sensor of the camera. Second parameter is the ISO-Number (that is the same even in analog photography).
Wouldn't it be correct to say that the profile could be made for each sensor-type (so one profile could be used for many cameras that use this Image-Sensor) ? Of cause camera built-in modifications (sharpening, ISO-handling, compression should be taken into account when building profiles for that image-sensosr.
Is there any information out there regarding the CCD-Sensors of the digital cameras in the market ?
Another question:
What size should the profile-test-image be for proper results ?
Is there any dependency of noise-profile to close-up features of camera ?
Thank you very much !
