Cesar R Posted August 14, 2003 Share Posted August 14, 2003 I found the following on the web, I m not sure if it really works, but I used to calibrate my screens. Is there something a little better? Link to comment Share on other sites More sharing options...
Jeff Mottle Posted August 14, 2003 Share Posted August 14, 2003 All this does it calibrate gamma. The standards are 1.8 and 2.2, but this grid does not say what it calibrates to. Link to comment Share on other sites More sharing options...
xgarcia Posted August 14, 2003 Share Posted August 14, 2003 Maybe this is a dumb question Jeff, but how exactly would you calibrate a CRT or LCD without using one of those Spyder pucks? Is there a freeware or web site that helps? Xavier Link to comment Share on other sites More sharing options...
Jeff Mottle Posted August 14, 2003 Share Posted August 14, 2003 Well without one there is no way to accurately calibrate a monitor, but I think the easiest thing would be to use Adobe Gamma. As far as color I'm not aware of anything free out there to calibrate a monitor. There might be something though. The one thing I should point out is that a monitor calibration alone is not going to help much unless you implement full profiling and use ICC profiles in your images. (There is a lot to this BTW aside from just turning it on) WIthout this each device you use (a monitor, printer etc) will react differently. Also if you ever send files to people they will never be able to see what you see. Link to comment Share on other sites More sharing options...
id_ivan Posted August 14, 2003 Share Posted August 14, 2003 if ICC file was attached, is it possible the one who receive the files will see actual file we see?.. just curious :???: Link to comment Share on other sites More sharing options...
xgarcia Posted August 15, 2003 Share Posted August 15, 2003 Man Jeff, you must be the must thorough person I know. Nice work. Xavier Link to comment Share on other sites More sharing options...
Jeff Mottle Posted August 15, 2003 Share Posted August 15, 2003 An ICC Profile that get's embeded into an image tells ICC compliant programs what color space that image was create in. However embedeing a profile alone is not enough. First the file has to have been created in a fully calibrated environment. That means a controlled environment (ie office lighting), standardised color space settings and a firmly establsished set of rules as to how you deal with images. The person that receives the file also has to be working in a calibrated environment and have adopted a set of standards as well. However it is not a necesity that they have the same standards as you. If they for example were working in a different color space when they opened your image they would be given the option to convert the image into their colorspace, or leave it as is. As long as both people are at a known standard the ystem will know how to convert accordingly. There are reason for both. The other option is to send users that will be viewing your files your colorspace file definitions from Photoshop and they can quickly switch their environment to react exactly as yours does. Thereby ensuring they see exactly what you see. Using ICC profiles without planning can actually corrupt your color data to a point where it can never be viewed properly, so make sure you are aware of that. I wrote an entire rollout document for Smoothe to implement color managment into the production environment and I have been meaning to publish those docs here, but I need to ensure that I have not missed anything. I'll see what I can do in the next while. Link to comment Share on other sites More sharing options...
muzzy Posted March 12, 2004 Share Posted March 12, 2004 I was searching for color calibration in this forum. Find your comments. Jeff. Do you still thinking to publish those ? Anyone has an idea, web site to calibrate CRT monitors ?No need professional quality or device based calibration...

Jeff Mottle Posted March 12, 2004 Share Posted March 12, 2004 Sorry about that. I've attached the last round of PDF drafts I worked on. I was never able to get the guys at Smoothe to actully implement it so I am the only one in a relatively calibrated environment. These are drafts so there could still be some mistakes as I never had a chance to get feedback on muliple systems and in different environments. Enjoy!

Craig Ramsay Posted March 15, 2004 Share Posted March 15, 2004 I read those a few months ago when you sent them to me Jeff, they were pretty much spot on I can highly recommend the ColourVision Spyder as a calibration tool... I wouldn't work without it now! Link to comment Share on other sites More sharing options...

Craig Ramsay Posted March 15, 2004 Share Posted March 15, 2004 No it wasn't a booth, we got a D50 lamp for calibrating the printers. It seems to work quite well... I have it set up in a dark room in the basement so that no light interferes. Link to comment Share on other sites More sharing options...
