  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Hard noise epic w

Hi Aleksandr, I've taken a look at the image and truly can't find any issue with it. You've under exposed which provides the low key look, which might be what was intended.

If you were aiming for a higher key exposure (or rather a balanced exposure), it is of course always best to attempt to get that in camera, but you can also grade this image fairly easily to "whatever" you want. This shot would land in the ISO 3200/4000 range for that, so you are 2 to 2.3 stops under if that was your intention and of course there would be noise if you are lifting any image that much.

If you are experiencing additional noise in Resolve, some have experienced that in the past. That's a resolve thing. I'd dig around and make sure your debayer resolution and all that is setup properly.

Flat out you can see youre underexposed by the histogram. Why is this being ignored, it is blatantly in the red.

Hi Phil! Yes, I understand what you're saying. But earlier, when such exposure problems when there was none. They appeared not so long ago. Yesterday me, a friend on this forum suggested that the need to increase the oven temperature to 44 degrees and do automatic calibration (earlier, I heard that it is better to do manually). I did the auto calibration, noise became less in my opinion. But I have seen the results of another person compared with their own , they absolutely different, worse in a few times. What else can you do? Again the calibration? To try manual? Or what?

I mostly run with Manual Calibration. Remember it gives you a small shutter speed/shutter angle range and you likely won't need to re-calibrate from 1/48-200th for instance.

With Auto Calibration you do indeed get a crazy range. I think it's 1/8th through 1/8000th. I find myself "not shooting like that often". However.

Personally I'd recommend Manual for most shooting days.

I think my camera is currently at 41 or 45 degrees. I honestly can't remember.

The shorter answer to all of this is if you want less noise, expose differently and possibly in conjunction shoot at a lower ISO with the appropriate exposure.

Again though, this image looks fine. So I don't know what's truly wrong here.

I grooved to 180 degrees. That is, if I need to shoot at 100 frames per second , I need again to do the calibration? Also.. why do I have so much noise despite the fact that I do the same thing what a man was doing that I suggested? What could be the difference? Is there still time to do it?

180 degrees may stay at 180 degrees but when you switch to 100FPS the SHUTTER ANGLE, it will no longer be 1/50th and will change and so will affect your black shading.

If you underexpose and then push in post you can pretty much count on noise. I looked at your shots and they seem underexposed. The fact that the lighting on the subject is boosting the RED channel will also have an effect on noise. Also, 3200 tends to be slightly softer and noisier than 5600.

Try letting a bit more light hit the sensor.

Just one more thing.

Is she being lit with stage lighting or your lighting?

Phil, since I use 1/48 for each day and 1/200 for slow motion. What will I choose when to start manual calibration? 1. Capture - 1/48, 2 Capture - 1,200? or should I do a separate calibration for them?
