									       Digital Photography Editing Workflow
There are two main types of computer programs for use in digital
1. Photo storage and sorting programs
2. Photo editing programs.

With the introduction of updated versions image organization
programs have more editing tools. No matter what program you use
you should follow a professional workflow to achieve the highest
quality image possible.

1. Preserve the Original
The original file often referred to as your digital negative should never
be edited. Make a duplicate and edit the duplicate leaving the original
untouched. This is so important the people at apple developed a
whole software package around it. Aperture is a digital image
management system with high quality image management and
adjustment tools for the advanced photographer. Aperture is
nondestructive image processing. Aperture protects your original
digital file as a Master and tracks all edits as Versions.

2. Rotate, Straighten, Crop
No one likes to look at a picture sideways. Rotate the image to its
proper orientation. Most editors rotate in increments of 90 degrees. If
your horizon line is slightly tilted then you will need an editor with
greater level of rotate control. Adobe Photoshop has at least three
ways to rotate your image. You can rotate at 90 degrees to quickly
flip from portrait to landscape and back again. You can choose Free
Transform and rotate manually however much you want. The
straighten tool allows you to draw a line on your horizon and
Photoshop will level it for you.
After a slight rotation your photo will need to be cropped. Cropping is
also your second chance at photo composition. You can crop out
unwanted information and bring the image more in line with the rule of
thirds. If you know what size you will print or publish the image you
can constrain the crop to those dimensions.

3. Adjust Tonal Range
Even the most basic photo program has a quick fix button that
automatically adjusts the tonal range of your photo. What these
applications are doing often is taking the darkest part and moving it to

black and taking the lightest part and moving it to white and all the
other values move with them. This might not always be the best
solution for your photo or the effect you are looking for. The
histogram is a bar graph with 256 points that represents steps in the
tonal and color range of your photo. The far left is 0 and is total
blackness the far right is 100 and is total white (there are 256 points
but most programs adjust on a scale of 0 to 100)
Level adjustments let you decide what will be the darkest and
lightest points in your photo by moving the related slider. Photoshop
allows you to apply adjustments in Layers so you can easily go back
and make changes with out undoing everything after the adjustment.

4. Adjust Color Tint, Hue, Saturation
The eye adjusts to the different color temperature of light but the
camera has to be told. White balance is a camera setting that
adjusts color to the light being used. Sunlight has a color temperature
of 5600 degrees Kelvin and has a blue tint. Incandescent light has a
color temperature of 3200 degrees Kelvin and has an orange tint.
Florescent light has a green tint. If your camera is not white balanced
for the light conditions your photos will have an off color tint that can
be corrected with the colorcast or temperature controls.
For effects you can adjust the hue slightly changing the colors in your
photos. For more vibrant colors you can increase the saturation. For
muted tones decrease the saturation. In Photoshop you can do the
color adjustments as separate layers and blend the layers by adjusting
the opacity of the layer.

5. Healing and Cloning
After making changes to the whole image if there are still problem
spots you can use the clone stamp found in Photoshop. The clone
stamp takes information from one part of the image and stamps it on
another area of your choice. There is also the healing brush that will
blend the tones in an area that the brush is used.

These basic edit are just the beginning of creating wonderful images.
Experiment with the many tools available in storage and editing
programs. Adobe Photoshop is the image editor of choice for
professional photographers and graphic artists. While other programs
have limits to what they can do Photoshop has a vast array of tools
and filters so if you can imagine it you can do it in Photoshop.
