DIGITAL PROJECTION CUSTOM COLOR PROFILE

Photography Committee

SEATTLE BRANCH


To maximize the quality of your photos being digitally displayed at the Mountaineers Potlucks we have put together a custom color profile which can be download to your system. You then convert the images edited on your system to be color matched to the Mountaineers Photo Committee projection system. However, it is important that your monitor be properly calibrated. Of the many places on the web that discuss monitor calibration, I have found Dry Creek Photo and Computer-Darkroom to be two of the best:

www.drycreekphoto.com

www.computer-darkroom.com

Use of the download profile assumes you are using Photoshop version 6 or above. If you use an image-editing program other than Photoshop, make sure it supports “converting image files”. The basic flow is, however, approximately the same.

After downloading the profile, you need to save it in a location that depends on what operating system you are using.  The profile files work equally well on Windows or Mac computers.

These locations are found on your c/: drive and are:

  • Mac OS 9.x: System Folder:ColorSync Profiles


  • Mac OS X: Storing profiles in /Library/ColorSync/Profiles allows all users to use them.  An alternative area, for users without Admin privileges, is /Users//Library/ColorSync/Profiles — any profiles stored here are available only to the current user.


  • Windows 98/ME: \Windows\System\Color


  • Windows XP: \Windows\system32\spool\drivers\color


  • Windows NT/2000: \Winnt\system32\spool\drivers\color
In Photoshop (or other photo editing program), edit your image until you are happy and save the file. Do all your editing in a standard color space such as Adobe RGB or sRGB. 

Finally, convert the image to the “Tahoma Room” profile. Photoshop users use the following path: (Image→Mode→Convert to Profile). This changes the data in the file to compensate for how the digital projector was calibrated.

Save the file as a tiff, or a jpeg as described in DIGITAL PROJECTION GUIDELINES.
