Obtaining Device Data for Color Profiling

RawDigger Target with Grid Placed

The RawDigger Profile Edition is successfully used for creating device data for color profiling of photo cameras; the profiles can be used for RAW conversion.

The Profile Edition allows one to digitize RAW values directly from the shot of the target, and export the results in the standard CGATS format, which can be read by most profiling software, including the free Argyll and DCamProf. The values can also be exported in the CSV format.

Using a separate shot of a grey card, or any matte surface ("Flat field"), compensation for target lighting non-uniformity (both for intensity and for white balance) can be done.

Dynamic Range: Your Fair Share of Flare and Glare

Lens Flare

Fairly often, the dynamic range of a camera is calculated in a perfunctory manner, based only on measurements derived from the sensor and electronics, and ignoring the limitations to the dynamic range imposed by glare and flare.

Glare and flare, two effects very well known in photography, occur due to the reflections and scattering of the light in the optical system comprised of the lens, any filters or adapters on the lens, the camera chamber (which, incidentally, includes the autofocus/autoexposure module located at the bottom of the camera chamber in many dSLRs), and the sensor sandwich itself.

It is very important to realize that glare effects, being so fluid, are hard to automatically recognize and compensate for in RAW conversion and post-processing. Let’s make a rough estimation of the effect of the flare and glare using the following simple method:
