Drill:
In your notebooks write a definition for each
of the following color harmony formulas.
• monochromatic color scheme
• analogous color scheme
• complementary color scheme
Lesson Objective:
Today we will use a digital photograph in order
to learn four basic colorizing techniques.The four techniques
that we will be exploring after desaturationg our full
color image are blending modes (color & multiply),
adjustment layer (hue/saturation) and masking.
Colorizing
Techniques (four basic techniques)
The four basic colorizing techniques can
be applied to our image after we desatuate a duplicate
layer of our full color image.
Desaturate Command
To desaturate our image we must use the "Desaturate
Command". The Desaturate command converts
a color image to a grayscale image in the same color mode.
For example, it assigns equal red, green, and blue values
to each pixel in an RGB image to make it appear grayscale.
The lightness value of each pixel does not change.
This command has the same effect as setting Saturation
to -100 in the Hue/Saturation dialog box.
Note: If you are working with a multilayer
image, Desaturate converts the selected layer only. (our
duplicate layer)
To use the Desaturate command:
Choose Image > Adjustments > Desaturate.
4 Basic colorizing techniques:
1&2 Blending Modes
• Color Blending Mode:
Creates a result color with the luminance
of the base color and the hue and saturation of the
blend color. This preserves the gray levels in the
image and is useful for coloring monochrome or grayscale
images and for tinting color images.
• Multiply: Looks at the color
information in each channel and multiplies the base
color by the blend color. The result color is always
a darker color. Multiplying any color with black produces
black. Multiplying any color with white leaves the
color unchanged. When you're painting with a color
other than black or white, successive strokes with
a painting tool produce progressively darker colors.
The effect is similar to drawing on the image with
multiple magic markers.
Hue/Saturation Adjustment Layer
The Hue/Saturation command lets you
adjust the hue, saturation, and brightness of a specific
color component in an image or simultaneously adjust
all the colors in an image.
Masking
You can obscure an entire layer or layer
set, or just a selected part of it, using a layer
mask. You can also edit a layer mask to add or subtract
from the masked region. A layer mask is a grayscale
image, so what you paint in black will be hidden,
what you paint in white will show, and what you paint
in gray shades will show in various levels of transparency.
Art Problem
Using all four colorizing techniques mentioned above to
create an original hand colored digital photograph. Use
the color schemmes to create balance and color harmony
in your photograph.
