common calibration tool

Because a gray scale ramp is only going to allow users to see a luminosity range, not wheter their gamma setting is right or whether the gray is actually gray or hued green blue or red, different monitors have different brightness contrast levels, my TFT is extremely bright and has a good range however my CRT was unable to discerne the lower and upper levels well.

Calibration can only be done correctly with fairly expensive hardware, most users will not have access to such hardware, software solutions are not very good because they rely on the users eysight and colour perception, but are better than nothing.

Most users of PCs have the colour space temperature set wrong at 9300k most professionals will have the temperature set to 6500k (daylight) or less, also the gamma on a Mac (1.8) is different to that on a PC(2.2) by default making the PC much more contrasty and the Mac flater.

So adding a little gray ramp to the web page is nothing more than false security a cosmetic solution that has little worth in reality.

Thanks, guys. I wasn't suggesting to substitute a complete monitor calibration with the help of a grayscale wedge. But it would be a nice little helper to adjust the angle of my laptop before viewing uploaded pictures... get my point? What brought up my idea was a question asked by a forumer: "Help - what happened to my pictures, they look so dark on my desktop @ work...?!" If every forumer had a nice little wedge visible in every photo.net page header he/she would know instantly, if at least brightness/contrast of his/her screen were somewhere near what a poster of a picture had in mind - because he/she had the VERY SAME wedge in front of him/her when posting... get my other point?<p>Third point: Is there any disadvantage associated with my humble design suggestion that I'm missing...? Cheers.

PS: The web designer added a light blue wedge to the header when the site was revamped lately - a nice touch, but a missed chance as well. A grayscale would have certainly been more useful, IMHO. But then, I'm just a photographer, not a web designer... ;-)

No real disadvantage, but surely there should be an advantage and for the reasons given I don't see any real advantages other than telling the end user his browser/screen is to dark or to light, maybe his lights are on or the sun is in his face or or or adfinitum.

Oh, well, Mark. If I didn't succeed in making clear the obvious advantages, I don't know what else to say. Please just reread carefully. And have a nice day, with not too much sun in your face, etc., ad infinitum... ;-)

The clarity of your writing will improve with the reading, nice on.

How often do I need to read it before the mysticism of your hidden intent becomes clear.

Perhaps I should rub lemon juice over my screen, and by the way I do not have a problem with the sun infact I wish there were just a little more but I am north facing so no chance.

Not all of us are blessed with constant monitor viewing conditions, Mark. Mine change constantly, see the situation as of yesterday attached. Please make my day by understanding that an unobstrusive gray wedge would help me adjust my laptop screen - whereever, whenever - be it for uploading my photos, be it for viewing yours. It's not that hard to grasp, is it? Cheers.<p><center><img src="http://d6d2h4gfvy8t8.cloudfront.net/2815662-lg.jpg"><p><i>mysticism? what mysticism?</i></center>
