Dropdowns to right of Histogram

[Bill Tschumy]

In the Viewer, to the right of the histogram there are two dropdowns. I don't think these are documented in the Help. The bottom dropdown affects the stretching via changing the Minimum and Maximum

The top dropdown seems to affect contrast or background levels. It has values of:

Off
2
4
8
10
...

What are these?

Hi Bill,

they are for stretching the image. i have then normally at something like 20 and low.

for the settings the hints should work.

i'm travelling. next week i have more time.
