I was thinking, the coeffs need be calculated only once for each<br>
|
|||
|
|
filmtype. So the user can provide a sufficiently contrasty slide<br>
|
|||
|
|
or neg with a sufficient amount of colors, calibrate on that and<br>
|
|||
|
|
save it as a profile. Btw, the calibration can be done on the preview<br>
|
|||
|
|
image.<br>

Yes my frontend does this already, together with 3x3 color correction<br>
|
|||
|
|
and some other color matrices for color saturation and stuff. Next<br>
|
|||
|
|
thing will be unsharp masking.<br>
