I get frustrated when I do postwork on a render to have it posted in a gallery. Everything looks great after i finish it and then i post it. When i try to look at my render from another computer, it doesnt look as good as when i worked at it from my computer. The image and shadows are too light so the overall dramatic effect is not achieved. i know its because not all monitors are calibrated the same way but is there a way to know whats the calibration for most computers? so i know that it looks good in most computers.

Try to darken the image a little with image-adjustment-levels (use only the gamma slider) :) Tihomir

There is no way to know that. Most people (mac and pc users) think that their monitor is ok or, in case it's too light or dark, simply set it darker or lighter. Apart from that there is also the limitation of the monitor itself. How close can it come to real black, white? How good are its colours? How does it display very dark and very light greys? Within the limits of your monitor, you yourself can use the Adobe Gamma Utility that came with photoshop, but it is about as limited as is the Levels Gamma slider compared to Curves. In case your monitor is calibrated regularly, you can indeed -if the owner of the other monitor permits it- "calibrate" it a little by using some images that have been created for that.

I have the same problem from my 19 inch Dell monitor. Not just a few, but every monitor I view my Posts in looks bright and washed out. I have had to learn to render with a very Low Gamma and then in post work, darken it 20% to 25% along with some Gamma correction. I had to do a few trails before I arrived at the 20 to 25%, by comparing it in the 'OTHER MONITORS'. My monitor is just dark and though calibrated as well as can be, it can not be lightened to emulate the look of other monitors. But, Everything is peachy now. 8-D

Thanks for all the help guys.
