To make the best color profile for your camera and lens combination, there are several adjustments that need to be made to the image of the SpyderCHECKR target image. In order to create a profile, photograph the target using your camera manufacturer’s RAW format then open the image in one of the supported applications.

1. Straighten, fix distortion and crop the target image.

2. Using the second lightest gray patch on the gray ramp, white balance the image using your application’s White Balance tool.

3. Adjust the white patch to an RGB value that averages RGB: 230 or 90%. If you are using Lightroom, move your cursor over the white patch to see the RGB percentages below the histogram. Adjust the Exposure slider so the measurements for RGB average 90% If you are using Phocus, move your cursor over the white patch to see the RGB measurements; found at the bottom right corner of the editing window. Adjust the Exposure so the measurements for RGB average 230. If you are using Camera Raw, select the Color Sampler Tool and place a target on the white patch. Adjust the Exposure so the measurements for RGB average 230.

4. Adjust the black patch to an RGB value that averages RGB: 10 or 5%. If you are using Lightroom, move your cursor over the black patch to see the RGB percentages below the histogram. Adjust the Black slider so the measurements for RGB average 5% If you are using Phocus, move your cursor over the black patch to see the RGB measurements; found at the bottom right corner of the editing window. Adjust the Brightness so the measurements for RGB average 10. If you are using Camera Raw, select the Color Sampler Tool and place a target on the black patch. Adjust the Black slider so the measurements for RGB average 10.

Once these adjustments are made, the target image is ready to be used to create a color profile for your camera and lens combination. To use directly from Lightroom, right click on the target image and select Edit In SpyderCHECKR. To use directly from Phocus, Export the target image as a 16-Bit Tiff then choose the SpyderCHECKR as the export destination. To use with Camera Raw, save the target image as an uncompressed Tiff. Launch the SpyderCHECKR software and open the target image.
