Color correction + add different set on graph cards

offonoll's picture

Hello! I don't really know why is changeing the performance color when I change the viewer from my main window to my send window. Here I attached a file. My MBP has two graphic cards as we all know. Could be that possible?

It looks like the second window respect the addition on particles and on main window doesn't. Or maybe the color correction from image render path. I can correct that by sliding a bit down a saturation color so I can see the interior more white.

Take a look on the file and I hope it reproduces the same effect.

Any explanation? and solution? Thank's!

Send window? What does that mean? can you be more specific/exact with what you are seeing? Maybe some screenshots?

Tested this, as best I could sans an MBP, on a dual card dual display setup. Couldn't reproduce the problem at all. MBP only perhaps ?

Not having had a mac dual display setup... but having had running DAW's on PC's... you aren't running the same type of monitor, inherently? Correct? Or does Apple make/have some kind of thing that is supposed to be exactly the same as what is in the laptop?

I guess, even if the display being used was the same, I would expect something in the path to be different, just because of the fact it's not the same electronics...

I'm not sure what dual display setup offonoll uses.

Mine is a heterogenous setup, hardware wise, one Apple and one generic [@75Hz] panel display available at present on my PPC.

Colour profiles usually the Display specific profile otherwise --> [sRGB - profile 1 option 1, Adobe rgb - profile option 2, srgb for most digital media {bless HP} & the Adobe RGB for print CMYK].

There are other colour profile options available most don't seem to do anything as the hardware doesn't support them.

If I knew what profile[s] offonoll uses, I'd be better able to try to reproduce his problem.

Yeah, I unfortunately know too much about color profile/monitor/raster image processing setups, this having been an intrinsic part of one of my jobs... but it was mostly PC stuff. It sounds like this is exactly the same scenario as far as monitor setup goes.

[general color/design philosophy rant:

The thing found was that it doesn't matter what the heck your profile is because the variance in monitors is so great, and there is a myriad of custom hardware available as well, but I always felt it was a waste of time. I shouldn't be THAT dismissive. There IS a difference, and it can be great... I always found that the tweaks were very specific to a piece of hardware. I would most often find myself doing custom profiles for users/monitor combos/whatever... people are finicky about that stuff (more so than me). I am discerning about color palette, but I believe that if it doesn't convey in the "broad strokes" and with some horrible compression, bad quality conversion, then it is inherently weaker. I feel the same way about audio.

Say you have something looking exactly how you want it... well, move your monitor 10 or 15 degrees up/down/left/right. Totally different now. Eh. I am jaded about the whole issue :o)

In my mind.... White and Black. Red, Yellow, Blue (or c,m,y,k and "paper as white"). Then ya mix them. If I was doing Million/Billion dollar marketing campaigns, I would be obsessive about these details as well, so I always felt obliged to indulge people's obsessive color whims (worked for a company that sold equipment to the AEC industry for a bit).

One may have some specific in between shades that seem really important, but the specific accuracy isn't as important as anyone ever thinks. And nothing on one monitor will ever resemble another, even with the same model many times, looking between one and the other discerningly, none of that will ever look the same after any kind of processing/conversion, and it DEFINITELY won't look the same if printed or presented in any other form of media.]

None of that helps my buddy Offonoll...

We gotsta know more to get to the bottom of it :)

Very informative post George.

Yes, we do need to know just what sort of external display offonoll uses, with what profile - display specific or otherwise, before we can approximate a close reproduction of the problem.

Seems as if Colour Management (CM) is coming up on numerous forums I frequent at the moment. It's such a crap topic to have to deal with as there is no easy 'in' without much basic science being covered and some experience sure helps. The joys of success are more along the lines of frustrated relief too. For my novice worthy five cents worth:

Colour Management is not about getting the same colour on different devices and media because whenever you have a different device and therefore a different colour gamut you have different colour output as a fact of 'light'. All colour management attempts to do is give a methodology for consistency and predictability of colour shifts so the process is "managed" to allow for some understanding of how what is being seen at one time will end up at the end of the workflow. Also it is to maintain the maximum fidelity in terms of the colour values by avoiding things like 'clipping' (to use an audio analogy) of the colour data when this is desirable. (This is presently done with device neutral reference colour-spaces eg Lab and a series of ICC device profiles).

Any of these managed processes can be rendered useless if just one link in the processing/profiling chain is garbage. Randomly assigning a profile to devices is pretty close to garbage in my mind, they need to be generated from a calibrated input/output and then devices need to be kept calibrated or the profile moves away from useful towards garbage depending on the self-stabilising quality of the device.

Yeah, that is a really eloquent way of putting it. You basically have to know your equipment and how it transfers to a variety of media, from the real world experience of trying it out.

I really like that way of phrasing it.

Hey guys! I captured my screen to show you the effect to understand what is happening, in case you didn't undestand me.

About the second screen I am using is a DELL 2208WFP. It's right! Could be the driver for the monitor but the point is that I like better the color effect on the dell screen rather than the apple screen.

Vimeo is very slow for the moment (5 hours converting queue) to show you the demo video. I hope tomorrow I can show you.

Thanks!!!

Re: Color correction + add different set on graph cards

Finally the video is done!

As you will see, defenetly its color screen prefs. Here you will see the differents on each color set.

LCD / disable color correction

ADOBE / enable color correction

DELL / enable color correction

RGB GENERIC PROFILE / disable color correction

sRGB IEC..-2.1 / CHEAP RED AND BLUE enable color correction

You could try with this with the new color correction test file. If you know how to change the profile set inside, please let me know. The utility colorsync doesn't allow me to change any profile color set.

thank you for the info!
