Optimal CFA spectral response

[Erik Kaffehr]

Any people shots with studio lights from those old CCD sensors? Thanks.

These were processed using my own profiles. Same images as before but processed a bit brighter. Same adjustments to both, except WB, color profile and exposure.


P45+ + LumaRiver


A7rIV + Lumariver

Now, the same images with Adobe Portrait profile


P45+ + Adobe Portrait


A7rIV + Adobe Portrait .

Draw your own conclusions.

An interesting point: Exposure will affect color in many cases. Part of that is that images have a tone curve. To handle that tone curve correctly, manipulation needs to be made in a color space that separates luminosity from hue and saturation.

Changing exposure may shift the tone curve.

In addition to that, camera profiles also have intended hue shifts that may vary with exposure compensation.

Best regards

Erik, your rig looks like something NASA would have for their Hassleblad Moon shots.

It's a Götschmann projector for framed 6x7 cm slides. Can also be used as a heating device.

I was pretty well established with 6x7 cm on film, with both 67 projector and a special slide scanner for 120 film.

But, digital came around.

Best regards
