Hey guys/gals....

I've been shooting with the 900 for about 3 months now and overall lov thepicture. I have noticed that the white levels are a bit hot, and it's not a matter of iris level. Any suggestions on knee/knee slope etc.?

I would set the knee slope a bit steeper, depending on where the threshold is. I like to keep a knee at around 85-90 IRE and compress after that. Its a bit low compared to the typical 90-95 setting, but I like my shots a bit more contrasted, and dont mind loosing a bit of dynamic range to get the crisp highlights.

If your highlights are comming out to strong, turn the slope down just a tad. then start adjusting the threshold. dont go below 75 or so, you get into the mid-fleshtones at around 70, so keep the knee off those colors.

In the end its a matter of taste that can change from time to time. You would be best served if you set it constantly to the situation. In overcast the knee can be off, but if you are in a hard backlight situation (IE, outside, sun to actors backs) you will find higher compression is needed.
