CHAPTER 13: Quick Changes for Your Images 265
6. You should see the image shrink on the screen. If you click Save now, you??™ll save your
image over the original??”destroying the original. Instead, I suggest that you save it as a
new file so you retain the original??™s larger pixel size. Choose File | Save As and give the
image a new name.
You might have noticed that you can also make images bigger using this procedure.
It??™s usually a bad idea to increase the size of your images, though, because all you
can do is stretch and multiply the pixels already in the images. The result is generally
unattractive, especially if you enlarge the image too much.
Save Photos in Different File Formats
Something I commonly do is change the file format of some of my pictures??”usually from
JPG to TIF, or perhaps PSD (which is Photoshop??™s file format). Why would I do that? Usually,
to preserve image quality. Every time you edit and then resave an image in JPG format, for
example, it loses a little quality (depending upon how much compression is used in the resaving).
TIF is immune from that kind of compression punishment, though, so if I need to edit a photo
that was originally shot in JPG format, I typically save it in the TIF format before I start editing
to (as they say in the zip-lock bag industry) lock in the image quality.
