Here is one I did earlier
Images have been taken on the NIKON D70s set to automatic mode – ‘point and shoot’
– with no exposure compensation used in any of the scenes.
The file has three images contained in it.
Ist layer is Nikon JPEG as shot.
2nd is my attempt to recreate scene using ACR from .NEF file
3rd is CIECAM02 processed from .NEF file, with this layer is a levels adjustment. The processed files were coming out of CIECAM02 dark. I did not introduce exposure rendering into the algorithm before converting to sRGB, opting to adjust in photoshop. (dont ask, had a few issues in this area but more interested in what CIECAM02 was doing colour wise). There is no other post processing involved.
So adjust levels to suit - I have my levels marked at the side - it would be interesting if I can get what your optimum level adjustments are.
I viewed this in dim environment on a sRGB monitor with a white point of D65, with the imaged toggeled to a black background in photoshop and all but the levels palette showing at the side.
Please give yourself time to adapt to the dim environment then toggle between layers to see the effect.
Woods near Inverness Scotland.
CAMERA SETTINGS • ISO 1600 • f 22 • 1/30s • 18mm WB 4650
CIECAM02 • La 500 • Yb 20 • ‘avg’ • Matrix D55 La 780
This is a typical Highland woodland scene. It was taken on a very bright day causing the
leaves to be backlit. There is not much white in the scene and the luminance levels in the
actual wood have fallen to about 500cd/m2. CIECAM02 has again has opened up the
shadows and has definitely increased overall colourfulness. This is especially noticeable in the
small areas of sky.
See what you think. Ill dig out some more.
Couldnt get pic to attach, dont think it likes tiffs so ive put int on my website
