Color Mixing inverts along with image inversion

[Christian Choi]

Color Mixing inverts in color inv mode - opposite from v1.2. Color mixing preferably should stay in tact when inverting movies so you can use your color mixing palettes to further color the inversions

how about both?

It's up to you, when I invert an images color, I often color it further and found it awkward to try to backward mix the colors in my palettes. It also seems I can't achieve the same degree of coloring as I used to in 1.2 for some odd reason everything looks washed out. Prolly my imagination from trying to mix backward.

Did you set up your screens correctly?
Calibrate them - change the dispay gamma ( the default is 1.6 on macs )

OS9 handles colour differently to OS 10.3
Apple also changed the way it handles colour in 10.3
Colour rendering depends on the output device - not catalyst.

i think the invert modes compress the hilites into a narrow range.
I added invert modes with colour the right way round.

Richard,

Maybe you have done it the right way around but the fact of the matter is that you are employing 2 different color mixing systems RGB(additive) and CMY(subtractive) now, whereas the better and less confusing way across the lighting platform was to just use the one more employed by lighting (subtractive) as you did before.

Here is exactly what is happenning in a more detailed description:

The standard (uninverted) color mixing system in the current and V1.2 Catalyst is based on the subtractive color mixing system i.e. cyan, magenta, yellow where 2 FILTERS combined = secondaries(RGB) and all 3 combined = black; however, since it is a video system and not white light being subtracted via filters to render color, the card's default must be additive color mixing (RGB). You must have cleverly devised a system which reversed and employed the standard lighting color mixing standard so that the colors would match up with encoders and logically mix more like a lighting fixture for us lighting folk. This all works Dandy in the Standard Catalyst *RGB default* mode even though it is really CMY not RGB.

Now, when the image is inverted, The color mixing system reverts back to True additive color mixing AKA - RGB where all colors mixed together = white and the encoders turn to red, blue, and green. This is the problem/bug.

In V1.2, the inverted color mode wouldn't affect the subtractive color mixing system and would actually color the inverted media without it approaching whiteout, instead it would darken the inversion.

In conclusion, you did do it the right way around, which is the problem, it needs to be back to the wrong way around in order for it to work properly and maintain continuity with the default color mixing system.

This fix would aid greatly with the Catalyst user's current color mixing palettes AND more importantly, not to wash out to white so quick by mixing in secondary colors.

Hope this helps, sorry if my first description was so vague.

no.

nothing in catalyst is cmy.
its all rgb.
its all rgb because the output device is rgb.
it makes no sense at all in computer->projectors to talk about cmy.

but computer cmy is simply 1-r, or 1-g, or 1-b.
there is nothing complex about this.

what you saw with inverted colours was simply a little bug, i liked the result, so i left it in.

i added inverted colour modes that do this correctly yesterday.

---

what you need to be very very wary about is talking about lighting cmy or printing cmyk or computer cmy in the same way- they are quite different.

operating in different image colour spaces is totally different from whats going on here internally in catalyst.

Sorry for my outrageos post, Richard. You fixed the bug. Thank you. I understand the preassures you're up against. I must have been pretty tightly wound those days. I think I was just really surprised when I got on site and all my colors in my palette were off and I had to rebuild them.

Wow, I'm sure glad I'm not working my ass off as I was back then. I was constantly frazzled.

My appologies,

Christian
