short gamma-comparison

I made some shots for comparing various gamma-curves:

all with detail-off, matrix-off, black/black-gamma/gamma-level 0.

If you'd like to see the effect on the actual gamma curve, connect the output to a WFM, turn on the maintenance menu and select SAW.

It's rather humorous to see people adopt CINE modes because that's what everyone else does. Here's a pretty good example of how whites get blown out and the whole image gets compressed into a rather flat looking image by using a CINE mode. Blacks have a minimum value of about 10-20% IRE and whites are around 95%.

I wonder why STD 4 Auto Knee caused the dog to run away.

Dominik,

Did you adjust aperture between each shot of the various Cine and STD gamma curves? Thank you.

No, nothing changed but the gamma-curves. Difference in brightness is caused only by the gamma-curves.

Interesting to see the difference in real world situations. Thanks for posting Dominik.

I have been shooting tests in high contrast situations, backlit, direct sun behind the subject, trees, leaves, foliage, reflections on water.

Std 3 auto knee was completely overwhelmed by blown highlights, but the manual knee was very good, providing all the necessary control. Turning on Zebra2 (100%) in conjunction with the histogram and (just looking at the scene in the LCD) was confidence inspiring with the two points plus slope of the manual knee adjustment. Easy to do on a tripod, but would be a real fuss handheld. With Cine1, it would be hassle-free but flatter looking image.

Dogs have issues with Std 4.
