Please forgive me for my stupid and newbie question.
I can't help wondering how's you guys manage to get a balance in deciding the value of Rendering Time and Sampling Level. I mean, you can count down the time and type in the Rendering Time that you can bear, but how about the Sampling Level ? If it's too high or low, the rendering is gonna be dark and noisy, at least this is what I experienced...
with a simple scene, a sky dome and a plane light, the rendering look acceptable in 800*600, but when I boom the resolution to 2000*1500 and sampling level to 60, what I got in the day after is just a VERY dark screen, I can see the object by tuning the level "extremely" high in PS, but it's of course, unacceptable.

Sampling level simply means how many times Maxwell will "halve" the noise of the image. Each pass takes time. The end of each pass is a completed sampling level. To complete each new sampling level takes progressively more time.

Suggestion: You do not need to fiddle with it too much. Leave the sampling level at 25, set your time to something high (like 9000min) and just stop the image when you think it looks good enough.

(In the past, with the alpha, images started looking good after sampling level 17 or so, but now things are different... they look good a little sooner)
