Monitor Calibration

Viewing images on a computer needs good calibration of brightness and contrast levels of the computer monitor.

Attention: if you are connected via AOL and use the AOL web browser, you might notice a poor image quality. A setting called "compress images" in the browser, that causes it to adjust images in the interest of faster transmission, causes this. You should turn this setting off before viewing any of the images on this site.

Black, White and shades of gray:
Below are two boxes, showing all shades of grey. You should be able to view all steps from clear white to black, if not change the contrast and brightness of your monitor.



Color:
The image below should appear as a rainbow starting and ending with red. There should be a smooth transition from color to color: with no banding and no little dots.

The image below does not have smooth gradations. This is the type image you see with limited monitor colors.

Or, you might see banding, like this.

If the topmost images looks like either of these, your monitor is not displaying all of the colors the images on this site use.
Upper two rows:
After proper monitor adjustment you should be able to see all small rectangles in larger ones. There is one small rectangle per each large one. If you can't see some of them your monitor is not adjusted properly.

Tiny lines:
What these tiny lines are for? These vertical and horizontal lines are intended to measure horizontal and vertical resolution of your monitor. You should view neighbor light and dark lines as separate colors. There are colored lines as well as b/w lines. Also the lines should appear strait not bowed.

Lower two rows:
These are for gamma adjustment. The inner rectangles are %50 gray, and the outer rectangles consist of equal tones of dark and light colors to make a %50 color. In a gamma-balanced monitor, you should see the outer and inner color mixtures in equal brightness. The grays should not be green or any other color tinted tone of gray.

Gamma adjustment:
The outer rectangles consist of equal tones of dark and light colors to make a %50 color. In a gamma-balanced monitor, you should see the outer and inner color mixtures in equal brightness.
