You can significantly improve the clarity and saturation of the color you digital camera creates by creating a custom profile for it. The defaults manufacturer’s provide and most people use are fine, but a custom profile built for your camera is better.

X-Rites’ Color Checker Passport can be used to quickly deliver more accurate color in a variety of ways.

Set White Balance, White Point, and Black Point

The X-Rite Color Checker Passport is the industry standard target that can be used in several ways to render color in your digital images more accurately – setting white balance, creative enhancement, and visual confirmation.

It’s easy to use. Shoot the Color Checker once at the beginning of each shooting session and you can use that exposure as a target for all exposures made under the same light. The exposure of the target doesn’t have to be perfect. Just, roughly fill the frame with the target; it doesn’t even have to be focussed. To use the exposure of the target, use your choice of Raw conversion software to open it along with other exposures you’d like to apply the same measurements to; click on the appropriate color patches (black for black point, white for white point, gray for gray point); and sync all of the files. It’s that simple.

Create A Camera Profile

The X-Rite Color Checker Passport can also be used to make custom profiles for your individual camera. You can create a camera profile with the same exposure of the target that you use to set white balance. While camera profiles are generated with the same target, the resulting exposures are not used to set white balance, instead they are used to deliver significantly improved color rendition and saturation, providing the best starting point for any color adjustment strategy you choose. Camera profiles are created with the X-Rite software supplied with the Color Checker Passport, stored, and later applied with your choice of Raw conversion software, typically Adobe Camera Raw or Adobe Lightroom.

For optimum results, exposures used to generate camera profiles need to be made under the light (color temperature and spectral distribution) that subsequent exposures are made in. Using two exposures of the target made under different light temperatures, you can create a dual illuminant camera profile that can be used for all exposures made under a wide range of color temperatures. Single illuminant profiles are recommended for exposures made under very warm or very cool light temperatures – below 3600K (golden hours) and above 6800K (twilight).

How do you make a camera profile? First convert one or more exposures of the Color Checker Passport from the manufacturer’s proprietary Raw format to Adobe’s open standard Raw format – DNG. (Use either the free Adobe DNG Converter, Adobe Bridge, or Adobe Lightroom.) Open X-Rite’s Color Checker Passport software. Click DNG or Dual Illuminant DNG. Drag one or two DNG files into the open window. Once the software has identified the specific color patches it needs to build the profile, click Create Profile. The profile will automatically be stored for you in Camera Profiles and will be available for your use the next time you convert a Raw file in either Adobe Camera Raw or Adobe Lightroom. You’ll find it under the Camera Calibration tab/panel under Camera Profile. Save New Camera Raw Defaults and your new camera profile will be automatically loaded when you open Raw files and previews in Adobe Bridge will be rendered with it.

You can see the significant increase in saturation and color clarity custom profiles make by toggling between the default Adobe Standard and the custom profile built for your camera in the Camera Calibration panel.

Using a Color Checker Passport target or a camera profile generated with it doesn’t mean that you are locked into the results they generate, they simply give you the best starting point possible for adjusting your images.

Profile Your Printer

December 21, 2011 | 2 Comments |

Prints made with default (left) and custom (right) profiles compared.

Good printer profiles help make good prints. Better printer profiles help make better prints. So, logically, you’ll want to use the best printer profiles to help you make the best prints.

How do high quality printer profiles contribute to print quality? A good printer profile helps render optimum shadow and highlight detail, gradation, neutrality and graybalance, as well as color rendition and saturation. (Remember, printer profiles characterize the combination of a printer’s hardware, ink, media setting, and the substrate you choose. You’ll need different profiles for different substrates on the same printer.)

How can you get good printer profiles? Look to three primary sources. One, use profiles provided by printer manufacturers; they’re free. Two, hire a printer profiling service; profiles cost approximately $100 each. Three, make printer profiles yourself; printer profiling systems run between $400 and $1000. (Profiles supplied by substrate manufacturers are of uneven quality; a few are good, many are bad.)

Which solution is right for you? It depends on both your printing conditions and needs.

If you’re using substrates supported by the manufacturer of your printer, try using the profiles they provide first; they’re often quite good. Years ago, Epson raised the bar on the quality of printer profiles provided by manufacturers. The highly sophisticated routines they use to produce their printer profiles processed by supercomputers are truly state-of-the-art. It’s arguable that you can produce better profiles, even with the most sophisticated profiling solutions available. Their profiling routines factor in subtleties like dot structure or screening frequency. One of the reasons a solution like this works is because the technologies and manufacturing standards they use are so consistent that the unit to unit variation between individual printers of the same model is extremely low. (It’s less than a Delta E of 1 or the minimum variation the human eye can detect.) Some, printer manufacturers, like Canon, provide a large number of profiles for substrates made by other companies; their quality is generally quite high with only a few exceptions. Other printer manufacturers, like HP, produce self-profiling printers. They need to be self-profiling, as the state of the printer is constantly changing; when nozzles clog, new nozzles come on line; when ink cartridges are swapped nozzles are replaced. One advantage to a system like this is you can quickly profile a new substrate on a printer with no additional equipment. The quality of the profiles is often good, but there will be times where you’ll want to improve upon it.

No manufacturer provides a comprehensive set of profiles that will cover the entire spectrum of fast-evolving substrate industry. A little experimentation with new media is advised, sometimes a lot. If you experiment with many medias or use more exotic substrates, you’d be well advised to have someone make custom profiles for you or do it yourself.
