Profiles were made for these monitors using GretagMacbeth ProfileMaker 4.1.1 software. The procedures to create and evaluate the quality of monitor profiles are schematically illustrated. The quality of monitor profiles is investigated. All tests were done on the Macintosh platform with Mac OS 10.2.3.

GretagMacbeth ([15]) offers Camera, a package consisting of a camera target and a software module called ProfileMaker 5. Camera is sold as a standalone package or as part of different Eye-One packages - e.g. Eye-One Photo. Gretag's Camera - supporting Windows as well as Mac OS - including a small (4 x 5 Inch) camera target MiniColor-Checker.

For serious camera profiling, however, you should consider ColorChecker SG, which may be ordered separately. It is larger, has many more patches and allows better profiles. It does come with a fierce price tag (around 300 US Dollars or Euro plus tax).

  • Use ProfileMaker 4.1.5 profile editor!!! In reply to Andrew Curatola. Jul 11, 2003 make profiles just only witht the best kits around, like Gretagmacbeth Spectrolino and ProfileMaker 4.1.5, or get a Pro doing it for you.

Despite this, it is of excellent color quality, quite robust and the colors should not fade for a long time, even when used in bright light.

The color patches show very little metamerism in varying lighting conditions.

To profile a camera using Eye-One Camera, follow these steps:

1. Take a picture of the target - we recommend ColorChecker SG - using the same lighting condition you use for a shooting session. Continue with your shooting and do the profiling before you process your images of that shooting session.

2. Convert your target image using standard settings with your RAW converter, then convert to a TIFF file. If you usually work with 16-bit TIFFs, convert the target image as a 16-bit TIFF, as well.

Carefully crop it, using the mouse with a cross hair cursor and the E3. Better to crop a bit tight than to include white surrounding space. You may even crop into the target area, if the image shows a perspective view.

Compare your target image with the image of the reference target. If their orientation and pattern of patches are the same, proceed.

8. From the drop-down menu Photo Task select the type of picture you took, and then from the drop-down menu Light Source select the type of lighting condition used for shooting.

9. The Options found in the dialog box with Photo Task Options let you tweak your profile for special lighting and color conditions.

Figure 11-5: Several options allow to adapt your camera profile to specific needs These should be used only if you have prior experience in profiling.

Clicking Start initiates the generation of the profile. You may see some messages, advising that the image is over- or underexposed. Ignore them.

11. Provide a descriptive name for the profile, naming the camera and lighting conditions, (e.g. Nikon-D70_Studi0_D50).

That's it! This profile may be used as a camera ICC profile with Ci or RSE or may be assigned to a converted image using Photoshop.

If your RAW converter does not support custom camera profiles, you should consider converting your RAW files without doing much color correction with the converter. Apply the generated profile to your converted TIFF or JPEG file using Photoshop:

1. Open the converted image with Photoshop, avoiding any profile conversion while opening.

2. Select Image ►Mode rAssign Profile from the menu (PS 9): EditrAssign Profile). From the drop-down menu of profiles, select the camera custom profile you generated using ProfileMaker for lighting conditions used for the shooting.
