produces large areas of solid color. By selecting a different color space such as
HSV or HSL, you can also create some interesting rainbow effects.
You can also click on the options button at the right end of the color line to reset the
entire color line to its initial state, to save a color line in a file for later reuse or
reload a saved color line. Picture Window comes with several saved color line files,
including one that creates a sepia toned effect, SEPIA.CLN. Once you load a saved
color line, you can use it as a starting point and apply all sorts of variations.
Finally, to tint just a selected part of the input image, first create a mask that isolates
the region you want to modify and select it using the Amount control in the Tint
dialog box. For more details on using masks, please see the Picture Window manual
or help file.

Method 2 Using the Paint Tool
The painting method lets you colorize parts of a black and white image using a free-
hand brush, similar to hand tinting. Effective use of this technique requires careful
color selection and some degree of manual dexterity.
There are two tricks to colorizing a black and white photo using the paint tool:
First, since you cannot paint color over an 8-bit black and white image, you
must first convert the image to 24-bit color. The quickest way to do this is to
use the Convert Transformation. By converting the image to color, you are cre-
ating a color image that looks exactly like the original black and white image
but now has 24-bits for each pixel instead of 8, thus allowing new color infor-
mation to be applied.
Second, select the Paint tool by clicking on the icon on the main tool bar
and then click on the icon in the lower left of the Paint dialog box and
select the HSV Hue and Saturation Only option. This tells the paint tool that
you want to apply only the hue and saturation of the color you are painting
with and you want to leave the brightness of the underlying image unchanged.
If you don't select this option, the paint tool will apply opaque or semitranspar-
ent color directly over the image; with the option selected, the underlying
brightness variations of the image are preserved while applying the selected
color.
Now all you have to do is to click on the color control in the Paint dialog box and
select the color you want to tint the image with and set the brush radius, transpar-
ency, and softness. Then zoom in on the image so you can get a close look at the
area you want to tint and start painting over the image. For more precise control
when using the freehand painting tool, you can use a mask to protect certain areas
of the image from accidental modification. For more information on creating and
using masks, please see the Picture Window manual or help file.

And remember, if the effect isn't quite what you wanted, you can always use the
Undo feature, adjust the color or other settings, and try again.

Other Tinting Methods
While the Tint transformation and the Paint tool are usually the best ways to tint
part or all of a black and image, there are other features of Picture Window you can
use to get similar effects. The following three methods also let you tint images and
they work with color and well as with black and white images.
The Filter Transformation can create effects like placing a colored filter over all or
part of an image. The colored filter can be all one color or can be a color image (of
the same size in pixels as the input image) that varies is color from place to place.
The Gradient Transformation is one common way to produce color images of this
type. Applying the Filter Transformation leaves black as black and changes white
to the filter color.
The Composite Transformation can blend a color overlay with an image. As with
the Filter Transformation above, the overlay can be a solid color or a color image.
Using a mask, you can vary the transparency of the overlay making it opaque is
some areas and transparent in others. Finally, you can obtain additional effects by
experimenting with the Operation control in the Composite dialog box.
Finally, you can use the Color Balance Transformation to apply tints to an image.
By setting colors to add for shadows, midtones, and highlights you can obtain
effects similar to those you get with the Tint Transformation and setting three con-
trol points on the color line.
