Fortumately,
Jasc PaintShop Pro has some good tools for doing precise color corrections
. We are using an image by Laura Jefferies, Claire, downloaded from
www.domai.com . Domai is a site where one
can find tasteful nudes done by Laura and others for a modest fee.
Here is a photo
that could be moved in either direction on the luminosity spectrum -
darker, dramatic lighting or brighter high key rendition. We chose high
key to emphasize the torso form and to fade out the background. However,
we do not pursue a full high key rendition in which only the figure
stays natural and the rest of the background fades to full or slightly
off-white. In fact we tried this intially by masking the figure , off-whiting
the background and bringing up the overall body tone.
|
|
The result was surprisingly flat and uninteresting. So that is the reason
to depart from the normal high key portrait or picture finishing style.
But the basic steps and techniques we use in this exercise applies just
as well to a full high key rendition.
Our first task is
to brighten and flatten the colors for the whole picture. Using the
Colors | Adjust | Curves dialog we simply bring up the overall tone
by 1/2 stop - using a mid curve setting does the trick quickly.
The next step is
a little trickier - we want to flatten all the tones towrds the middle
range of brightness. each program also has a histogram levels of input
and out tool to do the same task. |
|
Clicking on PaintShop
Pro's Colors | Histogram Functions | Histogram Adjustment brings up
the dialog shown to the left. Our adjustment works on over Lumninosity
though we could edit each of the RGB channels separately.
Our first adjust
expands the midtones slightly to compensate for a higher gamma setting
(brighter) set by dragging the gray median arrow to the right. Then
by pulling the low arrow to the right for a 10 reading and the white
output range slider down for a 230 reading, the overall brightness is
flattened and lowered slightly to a more natural, if bright skin tone.
Again, don't be shy about trying many settings because the results are
easily undone. |

two steps require finding the edges of the figure and blending two layers
together in a gradient transparency . The first task could be done in
Paint Shop Pro; but both are done much more easily and with more options
in Corel PhotoPaint. So we save our work and switch programs. As you develop
your software tool library you are going to find yourself doing this a
lot - just like switching utensils in the kitchen or tools in the workshop.
The field of photo editing is so rich with possibilities and different
features beyond the basic CAST set; that working with several tools becomes
second nature. |

In
Corel PhotoPaint, we create a second layer or object by clicking on
Object | Duplicate. This creates a copy of the original image and makes
this layer the focus of all edits leaving the original background layer
unchanged. If all goes well we will blend these two layers together.
Clicking on the
Effects | Contours | Find Edges tool brings up the dialog shown at the
left. This tool finds the edge areas in the image and outlines them
in gray with some hints of color. Its like an instant high key pencil
sketch. To clean up this sketch we |
| choose
white color, a soft brush with opacity set to 50%, and then daub in the
white areas to clean out the gray "cobwebs" left over from the
Find Edges tool and to give a cleaner, sharper sketch. |
|
So now
we have have two layers - one a bright color and the other a gray and
white outline sketch. Using the Interactive Object Transparency Tool (found
on the vertical toolbar second from the bottom - click on the the Drop
Shadow Tools black flyout option triangle and then choose the Transpency
tool - its a goblet with shadow icon.
The transparency tool is quite versatile blending two layers together
in linear, oval, square and other patterns . The linear pattern as shown
in the figure on the left is easy to control- just drag and drop the position
of the arrows to change the blends direction |
| and
rate of change. Use the middle white bar to change the transition point
of the transparency . This is PhotoPiant's powerful tool for controling
the transparency and interaction of two layers.
The final step is a lot of little touch ups the most obvious being adding
a light yellow green brushing to the upper right hand side of the screen.
In addition, a dark, dramatic lighting rendition of the same figure
was done. The figures below show the High Key and Dramatic Lighting
final renditions - you be the judge on which works better.
