What's causing the green tint on the URSA monitor?

PostFri Dec 01, 2017 9:14 pm

Hi folks. This might have been asked before but I'm not able to successfully search it here.
I have an URSA 4K and every time I look at the 10" screen it has a noticeable greenish tint over the image. I placed it side-by-side with a calibrated Canon C300 and the image is definitely greener. Why is this and how can I correct it? Thanks.

The design of this camera. I think the demosaic is 'weird' to that display and obviously non tune-able. The way the camera sets brightness to it is 'weird' as well. I'm surprised the pitchforks did not come out from early and vocal users circa 2015 about this.

The first Video Assist screens had a greenish tent also.

I had this problem with mine and now I rarely have it. I will do some research, but off the top of my head, I never have the problem in daylight situations, but only with artificial lighting situations and usually at night. But I need to do some research because I may have just gotten "used" to the tint. I'll let you know.

Your right Robert. It is prominent in artificial lighting, when I'm shooting in-doors. I've not notice it much during daylight. But I'd appreciate if you have some workaround. I look forward to any tips and thanks. I really like this URSA, it's form factor, and capabilities. It's been my workhorse for a while now.

There is no work-around. Aside from the brightness software control for the 10" monitor there are no colorbars or calibration dials of any kind, tint, wb, contrast. In newer cameras you can load a LUT to correct/calibrate/create a look, this one nope. Are you on 2.6 Firmware for the Camera?

So I did a test, took photos, tried different lighting situations and I don't have a green tint (anymore). And I have no idea why. I know it was there before because I remember being disappointed, but it is definitely not there now. And since I took white balanced photos of the screen and compared it to my URSA Mini screen, I know it not me just getting used to it.

I know that's not much help.

Yes, I noticed this too with the VA screens, they start out a little on the greenish side, then it improves with use. Just like the magenta edge issue with some Ursa Minis.

Ha... So I should leave it on for a while then hoping it goes away.
Also, I am on the latest firmware for the big URSA.
