View Full Version : Color Corrected?

The reason why I'm posting these images is to get input on the color correction and exposure of these images. I think I might have a gamma setting problem, since I just tried to calibrate my LCD with Spyder3 Elite and just need to see if these look good on your calibrated monitor/LCD.

According to a website my "highlights" are set correctly and my "shadows" are also correct. I can see every shade or gray, white and black and so both white and black points are set correctly.

Where my LCD fails is the gamma setting. When I look at the gamma image 2.2 I can clearly see the white and gray lines :(

According to this website I shouldn't be seeing the pattern at all, I should be seeing a gray patch.

For those of you that have calibrated monitors/lcd can you go to this website and tell me if you also see the same thing as my LCD? Thanks

Here's the website

I can see every range of black/gray and white from this website as well

Gamma should be removed from System32>Colors in your computer before using the Spyder. The small images you posted don't have lines on my monitor though. 16 bit will help you get smoother transitions.

I thought William was referring to the gamma setting of the Spyder software, not Adobe Gamma.

William, you need to squint a fair bit to make that "grey lines" thing work. I wouldn't worry about it too much. Your images look good to me on my calibrated ACD. (I don't like that pink top though - your red channel's gone!)

What kind of monitor do you have?

What makes you think you've got a problem? Have you had printing issues?

You may be right.I wasn't sure.

Unfortunately or fortunately I am ignorant enough to relay on my eyes for gamma. The key thing is not listen to everyone, including myself :)

I was referring at the gamma settings of my LCD (Dell 2405) I say this because my images look darker from what I was used to and also due to this pic that allows you to check your gamma settings. According to the website http://www.imaging-resource.com/ARTS/MONCAL/CALIBRATE.HTM So how do you tell whether your monitor is set to the correct gamma level of 2.2? It's actually pretty easy. If your monitor is adjusted properly, the pattern below will appear as all the same shade of grey when you view it at some distance from the screen, or if you just throw your eyes out of focus at a closer viewing distance. http://www.imaging-resource.com/ARTS/MONCAL/zgamma22.gif --William

Very normal. All LCDs are nuclear-bright out of the box, so they always appear dark immediately after calibration. Give it a couple of days, and it'll seem fine.

Yea, but you have an Eizo on the way. Factory tuned Gamma. Hmmmm (drool):lol:

Images look okay, maybe a bit on the magenta side...
I see no banding. (calibrated screen, albeit a laptop)

Alternatively: Have a look here (http://www.normankoren.com/makingfineprints1A.html#Gammabox) for a Gamma test.

On a side note: The page you linked to doesn't have a color profile embedded in the "test" images (black and white boxes and the blueish one; makes a *huge* difference whether I view them in Safari (which assumes monitor profile) or FF3 (which assumes sRGB))
