Thanks, so you just set the iterations to a lot and let it cook until it looks okay to you then you stop it?
I am curious now, which pixel filter do you use, Gaussian, Mitchell and Lanczos etc. same question goes to other people in here. I know there's a difference but I don't know what it is.
I ran tests using those filters on other software (Irfanview) and saved different images and compared. In the end, i found the Gaussian filter to be the smoothest, uses more blurring resulting is less sharpening. I found Lanczos to result in really sharp images, too sharp as I found it also emphasized noise in the image as well. I found the Mitchell filter to be the best with a nice balance of sharpness, without overdoing it causing noise. So I tend to use it (Mitchell). And as I have stated in the past, I use the Denoiser in my filter settings as well as you don't need as many iterations (I find 200 iterations is enough with denoising) to create a nice image, and the image doesn't have that grainy noise which bugs me.

BUT, everyone is different. I have posted the following two images in the past to illustrate my point. You cannot tell which of these two images used denoising and which did not at a glance.
But one of these used denoising, with 200 iterations and took me 5 mins. The other one did not use denoising and took me 45 mins.... you tell me if it is worth waiting 40 extra mins? I don't think so....

Oh I really can't tell the difference. Okay stupid question time. How do I manually set the amount of iterations and what's the best time for the denoiser to activate? I know there won't be a perfect number for it but I honestly still have no idea what does what when it comes to all the render tabs.

If you turn render quality off in the progressive rendering tab it will go to whatever iteration number you set.

This is my settings...

NIGHT HACKER RENDER SETTINGS.jpg

As for when to start iterations, I ran many tests, thinking that it would take longer if I started them too early. It doesn't. In fact, it goes just as fast, if not faster. I start right at the first iteration. It doesn't effect the quality at all as some have implied. I done renders where it waits until the last iteration, and I do renders where it starts at the first, and there is no difference in quality at all. BUT, if your video card is low on memory, starting at the first iteration (as I do) can help with that. I forget why, but all the images I post here have used the above settings.

I recommend trying out some tests of your own. Do one with denoising and my settings, and then try one without and a larger number of iterations then watch to see the time and quality difference (it's what I did, I wasted tons of time just testing with different settings).

Anyhow, it's "MAX SAMPLES" in the above setting image that sets how many it will do before it stops. And you can manually click "CANCEL" and save at anytime while it is rendering if it looks nice enough for you.

It will only quit prematurely with render quality enabled if it reaches 95%+, which if it does, than you don't need it to do any more samples and so it is okay for it to quit. It rarely will quit before 200 samples, mainly on really small images (like a small head icon, which I have done).
