Setting the Color-filtration controls (8)
On the front of the Daylab 35 are three
The filters are scaled so you can measure the amount of filtration for each color. Use "0= for no filtration. Or, increase the filtration by increments of 5, up to "80," the maximum filtration level.
As you evaluate the color balance of your image to determine what correction it may need, first select a portion of the image that should be neutral or gray to detect any undesirable color cast.
Whenever possible, look also at skin tones for improperly balanced color.
To eliminate the undesired color cast from your image, you need to add filtration for the complement of the color (for color correction, refer to the chart,
Correcting prints from co/or slides).
In color photography, light is broken down into three primary colors: cyan (greenish blue, magenta (reddish purple\ and yellow. By pairing these colors in equal amounts, you can create the following secondary colors:
CYAN + MAGENTA = BLUE
MAGENTA + YELLOW = BED
YELLOW + CYAN = GREEN
To add a certain color to your printed image, you must either add that same color with filtration or decrease its complement. Use the chart below to determine what filter or combination of filters you need to correct your image.
