Custom Calibration Test

[gatorlangman]

Hey guys, I figured since I'm going to be hooking up my computer to my HDTV I figured why not make a calibration file that has pictures that are 1920x1080.

Yes I could of just bought DVD essentials or some other calibration disk.. but why spend the money when you don't have to?

So I selected some colors.. I used photoshop to create the images. I chose pure colors.. pure blue, pure purple, pure red, pure cyan, pure green, pure yellow. I made sure they were pure by manually changing the hex numbers.

So here are the pictures(make sure to let them load all the way because they are progressive scan.)

And then I have had problems with different TV's and monitors having issues with the backlight shining through.. I can normally see it when the screen is completely black.. so I figured I would make a black image as well. So this is the backlight test picture.

Also note the reason I did black and white as a seperate image is because sometimes when a color is next to black or white it may apear lighter or darker than it really is.

on the black and white test, I also made a circle in the middle so you can see if your white is bright enough without compromising your blacks. I will soon make a flash video of a white ball moving fast on a black background for a ghosting test.


So you guys are welcome to use this calibration test I made if you want to.

So what do you guys think?

You need to buy the real disc, these jpg will do nothing, you have no pluge bars on your color bars, how is one adjust brightness, also hard to adjust hue the way you put the color bars without the other one below it, you need to look at a real ntsc colorbars, and photoshop default output RGB, for HD, we need 709 color space.

You adjust brightness when you have the black and white screen up... once you have that set you move to color.. those colors are pure colors meaning blue is 0,0,255, red is 255,0,0 etc..

I don't see why you would need anything other than RGB scale considering those are pure colors..im not trying to duplicate a ntsc color bar.. why 709 for HD? I understand when it comes to gradients but not pure colors...

I will modify my color though.. I think having the opposite color underneith each other is a good idea.

yeah I still dont understand why you cant adjust your grayscale first.. get it perfect.. cause I figure if you have a perfect gray scale then the brightness of your colors is correct. Then you can move onto how much actual color your different colors have.

For example.. if your blue's apear purpleish.. then you lower the amount of red.. if your red.. and so on..

If those are the pure colors.. you adjust your monitor untill those colors appear to be perfect... isnt this the goal? to have your blues to be true blue and your greens to be truely green?

Read this and you will understand why your color bars won't do anything.
