  • 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 :)

The traffic lights don't work properly under 320ASA. The values don't map high enough to trigger them. We can see from the IRE monitor what the clip values map to when we use 250ASA or lower. Is the an effective way to lift those values so that clipping is shown?

Sure, but if you want to expose for redspace rather than raw?

It always displays raw. The last one (red) is clipping. The colours are based on the false colour mode, I believe.
 
The histogram reflects the colour space you are in, so set up a raw button to flip to raw to expose. The rainbow bar is always in raw, but use it as guide and I wouldn't base my whole exposer based on that alone, as is just like a spot meatier of the whole picture. the traffic lights are the same as the rainbow meter but sowing the scale in false colour spectrum just showing when you have things falling of in to the shadow and highlights, but is calabrated to the colour space.

as it has said before this dose need to be clear in the maunal, and i think the camera should say when you are in raw and you colour space

you can also set up a RGB parade that will always be set to raw no matter what colour space you are in.

although red haven’t put in what is calibrated to what in there manual, alot of this information can be found in said document. RTFM

The traffic lights show when a channel is clipping.

The histogram does reflect the colour space you are in, but it doesn't do it correctly if you go under 320ASA, however many times you "read the f*cking manual"

Not really the same thing. I want to rate the camera at 200, not lose a stop of light.

Rating the camera 200 means you have to overexpose 2/3 stop anyway compared to the specification.

I'm not sure I understand what you're trying to achieve. If you want a 200ASA camera you need more light than at 320, which means you're either trying to reduce noise in a low-contrast environment or you're in a high-contrast environment and are worried about clipping.

If it's the first, leave the camera set at 320, put your meter on 200, and light and expose accordingly - with an eye on the traffic lights.

If it's the second, use ND.
 
I'm trying to rate the camera at 200ASA partially for the reduction of noise, but there is more to it than that. Yes, I can leave the camera at 320 and use my light metre, but then I am not seeing the image at 200. It will look brighter and less contrasty on the monitor at 320.
