If you are using Photoshop, you can save a "work in progress" as a Photoshop
file (psd) and it doesn't degrade (compress) further. When you re-open a
..psd file, it's as if you never closed it - no next generation image
degradation. Try to refrain from saving a JPEG repeatedly as each time a
JPEG is saved, the image (file) compresses further. If you receive JPEGs,
it doesn't matter to convert it to BMP since the original JPEG has already
been compressed at least once; you're not adding more information to the
image by converting it.
Your situation sounds like one that I had creating wake/funeral brochures
for family. I can tell you that consumer grade scanners aren't that great
at rendering subtle differences. For example, I tried to lessen the
contrast to see more shadow detail and there wasn't any. That is the
scanner's shortcomings more so than the file format (JPEG), and note the
images I received were provided from more that one person (scanner) yet all
were similar in this regard.
Photo Optimizer? You get the watermark on your photos because it's a trial
version; once paid, the watermark isn't applied. If you have a digital
camera, you may have the included photo editing software already on your
computer; try that. IrfanView (http://www.irfanview.com/) is a free
all-purpose image viewer and has some photo editing functionality.
Remember, don't keep hitting the Save button and overwriting the previous -
with each Save, the JPEG compresses and artifacts multiply.
If you're confident the photos will need to be enlarged, enlarge them
yourself - work with the enlargements. Allowable email attachment files are
pretty sizeable now (Hotmail is 50MB) so there's no reason you can't go big
for an important project. Another option is upload the image to the
Internet and the recipient can download (example:
http://explore.live.com/windows-live-skydrive). Better if they have to
shrink your photos instead of blowing them up to print or otherwise.
Something I learned during the funeral... punch up the color
saturation/vividness/contrast (just before detail is lost). Washed-out
photos are worse when printed and/or projected on a large screen in a not so
dark room.
Photoshop guru's... please let me know if I'm mistaken in paragraph one,
etc. (to include top posting).

Been helping out a friend with old photos. Fixing them up a bit from tears

Trouble is he received them as jpgs and can't get the originals to scan them
in for me as a better format like BMPs.
Am I flogging a dead horse here, working with jpgs and returning them as
jpgs?
When I get them I save as BMPs a copy to work with. When I have finished I
keep the BMP for me, and send him back the jpgs as it is better for him
(smaller file).
I have Photo Optimizer, but I have noticed on other photos that it leaves
the words like ........... . com on the bottom.
These photos are later to be used elsewhere and maybe enlarged. I feel that
enlarging them later as jpgs will mess them up worse than they are.
Any suggestions please?
Thank you as always
