When I look at a render in the render output window it is lower resolution that what I see in Photoshop after saving the image. This lower resolution makes the scene look much noisier than it really is. This is problematic because I think I need more rendering passes than I actually need and waste time waiting for them to generate. Also, the image appears wildly less saturated than in Photoshop -- sometimes it looks B+W.

The live preview window on the other hand always has a strong olive cast. This makes color tuning materials impossible. It is really odd how off the color is here compared to full renders. It actually looks monochrome render in olive ink.

I have gamma and LUT adjustment turned off in 3ds Max and I have Octane and Octane cameras set for gamma = 2.2.

What can I do about these problems?

What viewport do you use? Octane ore 3dsmax standart one?
Both have zoom, you can set zoom to 100%(1:1) to see actual resolution.

If you want to use octane gamma, use linear response. Otherwise set octane gamma to 1.

Clarifications.

"When I look at a render in the render output window it is lower resolution that what I see in Photoshop after saving the image."

What I really meant is it is much noisier than when viewed in photoshop. Perhaps this is just a poor scaling algorithm thats downsamples to the viewport crudely exacerbating the noise?

"The live preview window on the other hand always has a strong olive cast."

I am referring to the Octane live preview pane. I do not understand why the live preview and the final render would have such dramatically different tone.

You have to check noise level at 100% zoom.

Can you show your pictures?
Are use sure you totaly switch off 3dsmax gamma?
