Grand_Canyon.jpg
Two Defaults
When you save a file for the first time, two defaults are encountered.
Default #1 - Save As
Photoshop Elements will open the Save As window, not the Save
window.
Default #2 - Photoshop File Format
Your edited file will be saved, by default, using the Photoshop
file format.
The extension for this format is .psd.
The Photoshop file format (.psd) has two advantages and one disadvantage.
Advantage #1
When a photograph is saved as a PSD file, there is no loss of
quality no matter how many times the file is edited and saved.
In contrast, every time you edit and save a JPEG file, some of
the image detail thrown away.
The quality of the JPEG photograph degrades each time you edit
and save it.
The JPEG file format is called a lossy format because image detail
is lost due to compression.
Advantage #2
The layers are preserved when a file is saved using the PSD file
format.
You can go back, at anytime, to make changes to the layers.
Photoshop files have one disadvantage.
Disadvantage
Photoshop files are large.
However, memory is inexpensive.
If your hard drive is filling up, use an external hard drive.

Save as a JPEG
If you're going to print the photograph, or send it in an e-mail,
you'll need to save the file as a JPEG.
Do the following.
1) Go to File > Save As, or press Shift + Cmd + s.
The Save As window will open.
2) Locate the Format box and change the file format from Photoshop
to JPEG.
3) If selected, deselect Include in the Organizer.
4) If selected, deselect Save in Version Set with the Original.
5) Don't save the edited version of Grand_Canyon.jpg over the
original file.
Look for Save:, and then select As a Copy.
Or, append -edited to the file name.
By changing the file name, your original file will be preserved.
6) Click OK.
7) A JPEG Options window will open, prompting you to select a
quality level from 1 through 12.
Use 12 to preserve as much image information as possible.
8) Click OK.
You'll now have three files located where you store your photographs.

Refresh Thumbnails
After saving a file, you may not see the thumbnail for the
file.
Go to Folder > Refresh Thumbnails.
Use caution when deleting with Picasa.
Delete & Picasa
Deleting Thumbnails
You can't delete just the thumbnail from Picasa.
If you right click on a thumbnail, and select Delete from
Disk, you're going to:
• Delete the thumbnail.
• Delete the file
from your hard drive.
Deleting Folders
If you right click on a folder, and select Remove from
Picasa, you're going to:
• Remove the folder from Picasa, but not from your hard
drive.
If you right click on a folder, and select Delete Folder, you're
going to:
• Delete the folder
from your hard drive.
Hide a Thumbnail or Folder
What if you don't want to see your klinkers, but you don't
want to delete them from your hard drive?
You can hide a thumbnail or folder.
Go to Help on Picasa for instructions.
You may encounter the TIFF file format.
TIFF File Format
The TIFF file format is used by some photographers for printing.
As described above, all JPEG files are compressed.
During the compression, image detail is discarded.
In contrast, the TIFF file format has two modes, uncompressed
and compressed.
There is no loss of information when using either the uncompressed
or compressed TIFF modes.
When using the TIFF compression mode, the TIFF algorithm looks
for patterns, such as the repeated pixels of a white wall.
The white-wall pixels are deleted when the file is saved, compressing
the file.
However, the deleted pixels are recreated by the TIFF algorithm
when the file is reopened.
