The following steps are effective for most images using
Photoshop Elements. There is much more that can be done.
Cropping:
-
Open the JPG file of the original photo.
-
File > SaveAS the image, give it a meaningful name, and change
the file type to Photoshop's PSD format. Do not ever edit the
original!
-
Click the Zoom tool to explore the image with any combination
of: clicking on the image, click on "Actual Pixels" button, and click on
"Fit to Screen" button. Before doing the next step, click the "Fit
on Screen" button that shows when the Zoom tool is active.
-
Crop the image by first clicking the Crop tool. Hold
down the mouse at one corner and drag out a rectangle. Adjust the
rectangle. Double-click inside the rectangle to complete the process.
A useful option for prints is to type in dimensions in the parameter section
for the crop tool to force a height to width ratio of 8 to 10, for example.
Color and Contrast Enhancement:
-
Enhance > Adjust Brightness/Contrast > Levels ... (not the
Brightness/Contrast). While in this dialog box, you adjust the histogram
range to enhance the image by sliding controls affecting the highlights,
midtones and shadows. (See Figure 3 below)
-
Move the rightmost triangle under the histogram to the left
to adjust the highlights. In general, slide it to where the histogram
is beginning to approach zero. In this case, that is about 185 (notice
the numbers that change).
-
Move the left slider triangle a little to the right about
to 10 to adjust the dark area. In general, slide it just past where
the histogram becomes positive.
-
Move the middle slider triangle to adjust the midtones.
This example doesn't require much movement.
-
Click OK. (FYI: this will stretch out the histogram
to cover the full range from dark to light, which is what Ansel Adams touted
as the desired Zone System. See Figure 4 below.)
-
If you do not like the results, click on the "Step Back (edit
undo)" button. In fact, you generally want to bounce back and forth
with Step Back and Step Forward to compare the change with what you had
before. In addition, you should zoom in and compare the changes,
particularly if the photo was taken in very low light.
-
Enhance > Adjust Color > Hue/Saturation. In this dialog
box, move the center slider on Saturation a little to the right to about
10 or 15 to add some color richness. Beware that increasing the Saturation
much more will likely cause some unwanted artifacts.

Sharpen (don't do this if you want a soft mood)
This is generally the last thing you do to the image.
-
If you had any selections open, do a Select > Deselect before
doing the following sharpening. You should also flatten any layers
if you are using layers.
-
To Sharpen the image for printing and web pages, use Filter
> Sharpen > Unsharp Mask ( or simply Sharpen). The Unsharp
Mask is used to sharpen, but you might not figure that out from the name.
In the dialog box, move the Amount slider between 100% to 200% (usually),
the Radius slider to 1.0, and the Threshold about 5 or 10. The precise
meaning of these parameters is a long story.
-
Click OK.
-
Bounce back and forth with Step Back and Step Forward to
compare the change with what you had before. Notice the necklace
on the woman in the center.
Save the work - this is still the PSD file.
Prepare to Print:
-
To ready an image for a print at a photo printing store,
open the PSD image file (if it is not currently open) and do a File > SaveAS.
-
Change the file type to be JPG.
-
Change the name if you want.
-
When you click on the Save button, the JPG dialog box appears.
For printing, be sure to save at the highest quality possible with the
least compression. That is a Quality of 12 in the JPG dialog box
for Photoshop Elements, with the slider all the way to the right.
-
Click OK.
This will yield a large file size. You can then copy
the JPG image back onto a memory card and take it to the printer shop.
Note that most budget printing stores only accept JPG image files, thus
the conversion to JPG is necessary. If you are printing at home,
you can print the PSD (or TIFF) file directly from the editing software.
See Printing page.
Prepare for the Web or Email:
-
To ready an image for a web page or an email, open the PSD
image file (if it is not already open).
-
Image > Resize. In that dialog box, enter a number
for the Pixel Dimensions at the top for either the Height or the Width
(but not both). For the example shown on this page, I set the Height
to 420 pixels. VIP: make sure that there is a check mark at the bottom
next to "Constrain Properties", and also a check next to "Resample" usually
with the Bicubic option. Do not try to resize an image to make it
larger. It will be larger, but it will usually look like crap.
-
You may want to sharpen the image as I did above. The
sharpening done above was at the higher resolution, thus one pixel of sharpening
at the high resolution might not be visible in this smaller resized image.
In general, sharpening should be the last thing done and it is resolution
dependent.
-
Save this image in a different file via File > SaveAS and
change the file type to be JPG.
-
Change the name to something different from the printable
file.
-
When you click on the Save button, the JPG dialog box appears.
For web pages and email, you want a fair amount of compression so that
the file size is civilized. Move the Quality slider to the 6 to 8
range for most web images. As you move the slider, you will see the
file size and an approximate download time for a 56K phone modem.
-
Click OK.
