make these prints look more natural, process them with Digital ROC, then use your image-
editing tool to mix the channels like this:
Red = 120% R – 20% B
Green = 20% R + 70% G + 10%B
Blue = -30% R + 90% G + 40% B
Make pictures of people “warmer.”
In general, skin tones look best when the image is slightly orange, as if they were taken in
candlelight. To make images warm with Digital ROC, adjust the Red-Cyan slider to add a little
red and the Blue-Yellow slider to add a little yellow. Experiment with different settings to get the
best effect. A good starting point is +5 for the Red-Cyan slider, and –3 for the Blue-Yellow
slider.
Turn off enhancements when scanning faded images.
The Digital ROC plug-in analyzes your images to detect and correct the color and contrast. This
analysis works best when the digital version of the image closely matches the original print or
negative. Because scanner functions that automatically correct the contrast or sharpness may
make it more difficult for the Digital ROC plug-in to extract the information it needs from the
image, you may see better results if you adjust the image after processing it with Digital ROC.
5 TROUBLESHOOTING
Faded prints turn purple and green.
Some types of photographic paper fade in such a way that all the information from one dye layer
is lost. Without that information, Digital ROC is unable to determine some of the original colors
from the print. An expert can make the images look more natural by copying information from
the existing colors into the missing color using a channel mixer.
I try to run the Digital ROC plug-in but get the error message "Could not complete
the Digital ROC command because there is not enough memory (RAM)."
You do not have enough free memory (RAM) to run Digital ROC because of the size of your
image. The Digital ROC plug-in performs a very sophisticated analysis of the image that
requires more memory than simpler plug-ins. Try to increase the RAM or swap space available
to your host application. You can modify these settings in Photoshop, for example, under Edit-
Preferences-Plug-ins & Scratch Disks, and Edit-Preferences-Memory & Image Cache. You can
also try reducing the size of your image by reducing its dimensions or resolution prior to running
the Digital ROC plug-in.
