In our collaborative animation project, my partner uses IMac and I use Gigabyte P25 laptop. In the post-production phase, we tried to calibrate our screens. No matter how much we tried our screens do not look similar. Also, my friend's İmac looks too bright but it is not something linked to screen brightness, it is shining. Maybe my screen is too desaturated.
Do you have any suggestion about how we should calibrate those 2 screens? And which one of our screen is the closest the true one? When we calibrate with the built in tools, my friend's screen is yellowish, mine is bluish...
Okay so you will need to do your calibration in the same room with the same lighting conditions:
Bright room, white walls, ideally "daylight" balanced, broad-spectrum bulbs (fluorescent or incandescent). If the room or office is dark, light the wall behind or backlight the monitor. Again, use daylight or broad-spectrum bulbs.
As for the color balance, Apple has a a great little tool (use Expert Mode) which allows you to fine-tune the color on your machine and create a color profile to use for later. I"m not so sure with PC - Photoshop used to install a great little color profile maker for Windows, but I don't think they do that anymore. I don't even own a PC anymore so I can't really say.
Remember: dark rooms make for dark images (your eyes adjust to the dark and what you think is white is actually grey and your blacks get crushed). Bright rooms make for better images. Make a new color profile for each situation: accommodate for windows, room brightness, time of day (sun/no sun), overhead/side/back light, incandescent/fluorescent, balanced for "soft light" or about 2700K, daylight (about 5600K), wall paint color, or other lighting.All of these have an impact on how we see color. To properly balance light, be sure to take the whole room into account.
If you do both machines at the same time, you can compare the same image on each machine. If you can afford to buy a color calibration package (like Spyder), you can get very precise. They have them for PC and Mac.
Remember to do your color calibration often: colors will shift over time as monitors, LCD elements, wiring, and tech in general age. I do mine once a month and more often with heavy use.
