  • 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 :)

I miss the pre-20 false colour

I just got my MX back from red and I must say its crap, you cant shoot at 20000 iso! But I did a couple of tests at 3200 and the results were mind-blowing. Crash your blacks a bit, lower the blue channel another bit(that was a strange comeback of pure blue grain under tungsten, I remember that in build 20 it was quite colourless) and you have a perfectly acceptable image.

But I miss the old false colour, the one before build 20 with the full colour scale from under to over. Now(unless it's a bug) It's purple in the shadows as in 20 and above, but the rest is just grayscale. Of course its pretty easy to meter with the histogram but I always loved fc...
 
I have to agree with you. I just loaded Release Build 30 and the false color is severely handicapped. The bright information doesn't go past yellow anymore, and the darks are inconsistent. This used to be so dependable when it first came out. I'm not sure it really works that well anymore. Why did they make all of these changes, FLUT, color science?

20000 ISO? You might want to rephrase that statement as it makes it sound as if the R1 M-X is crap, which I would have to disagree with you if that's what you meant. My findings so far is that I like the image at ISO 200-2000, but once I get above that, the results vary depending on the scene and what I'm trying to go for. But to call the sensor crap, I don't think that's what you meant.

I believe the new false color was based on feedback from many people about what they wanted from false color.

You might wanna have your sarcasm filter checked out, I think it's broken.

Haha, he might have got me on that one, although the 3200 is mind-blowing comment sure was an indicator. :redface:

Okay, sarcasm filter back in service. Carry on.

I agree, I understand having the extra Exposure False Color, but I don't understand eliminating the Orange & Red from the Video False Color.

SI2K's False Color is really nice and worth taking a look at. Can't say the same about the rest of the camera.

SI2K - I don't know anyone who has shot with it. I don't think there even are any on the rental circuit here in Montreal. What are the disadvantages/advantages?
 
This is what I got from Stuart a while ago. I wasn't really happy with the answer. I don't see why the exposure info needs to be split between two overlays, and makes less sense that you have to toggle between the focus overlay to be able to see both (multi button). I just treat straw as the old red, along with the histogram and goal posts.

Guys, the old colour overlay is still there but it's switched to the MULTI button which toggles through the various modes. I've set our camera's top left LCD button to MULTI and it works fine, then I use the 1 button to toggle False Color on/off which keeps the last state the MULTI button was set to.

Yeah, I found it today when I did some proper tests, but still it's not the same as the old one. The 80-110 IRE range is not as detailed. What I do love though are the two red bars for over/under. I'm still trying to figure out the correct iso of the camera, it came back with 800 iso as default, but when I switched to RAW view it looked way under and only when I dialed down the iso to 320 it looked the same with RedColour. Anyway, lots of tests will be done in the following days.

Nathan, Exposure info is NOT split across two overlays.

There is a sensor exposure overlay (purple and red) and an RGB monitor path video level check.

With Bulild 30 FLUT color science, to verify exposure you ONLY need to refer to the first.

See the Operations Guide for more details on each of these.
 
Hi Stuart. I have to disagree. I believe that not having any visual reference of range above 80 IRE in FC is a definite hinderance to the system. I appreciate the sensor clip and noise overlay, but the most important thing in FC is to map the entire range of tones. I understand that somehow the FLUT gamma or curve, or whatever it is keeps the signal from going over 108 in that gamma/color space, although if the image is clipped on the sensor or close, I need to know what I'm getting in that 90-108 range. it just seems that the implementation of the new FLUT is powerful but it also adds in some ambiguity as to what you're getting in the higher IRE ranges.

To see how FLUT controls the development of sensor RAW data into the RGB domain, enable the Video Level color overlay.

At ISO 800 with Mysterium-X, you should see that the Green video level overlay aligns with a standard 18% grey.

PURPLE, RED and YELLOW are not missing from the Video Level color overlay, but FLUT™ acts to prevent RGB video hitting these values.

You can force these colors to appear issue by adjusting SHADOW or EXPOSURE or RGB GAIN..

Sorry Stuart but the Manual explain literaly and with images about falsecolor red and purple and this, YES, is missing.

The problem is most serious than Red imagine, most DPs are accustomed wait for the Red color to avoid it and most of them are overexposing. I never work with a B30 cam. No rental houses here install B30.

Best,
Vico.
 
Hi Stuart,
Could you explain this a little more. Is FLUT stopping the sensor from clipping or becoming under exposed? It doesn't really make sense to me. Surely if something is clipped then it must turn Red yes? And if it's within 0-1 IRE it should appear purple?

If FLUT is doing what you say it is doing then it sounds like a step backward. Nothing should stop the readout telling the operator that the sensor is actually operating between 0-1 IRE and 101-109 IRE surely? That flies entirely in the face of having such a video false colour doesn't it?

If the FLUT is controlling the output so that it looks pretty on outputs that's fine but when it comes to a metering utility FLUT should turn itself off surely and we should receive a false colour signal with what the sensor is seeing precisely no?

Thanks
Paul
