Calibrating the Macintosh screens

[samsc]

Was quoting danny on 2.2 tv gamma. Downstream of me, I just put up the b&W GRADIENT and they (projector people) adjust ct, though they sometimes ask if I can raise it for them due to lamp issues.

each projector will have its own native or progammable gamma:
How one goes about calibrating this stuff really has to be based on what works, looks good, doesnt distort hilites and colour, unless that is what the end user wants?

the issue is that mac screens are setup with a less steep gamma curve that pc's, macs default to 1.6-1.8.
This means that images produced on a mac look different on pcs.

One cant really compensate for the green or brown tones that old bulbs give off.

I added a new ui HUD in f24.

It shows the current gamma transfer function across both displays.

This allowed us to check that all the displays in istanbul where using the same output gamma, which was important for the screen processors doing the overlap.

How do i use this?

This is set by the os and colorsync.

The 'Displays' preferences allow you to set a calibration for each screen.
this is what the calibration effects.

There is a rather good piece of software called 'Profile Maker Editor' from GregTabMacbeth that allows you to make a curve in any shape you want.

You cold use this to create a screen profile that was optimal for a DL1 in certain conditions.
