Storing photos ready to print

So your digital camera has taken a picture at 1600 x 1200 & you transfer it
to your PC. What determines at which resolution the files sits on your PC?
Can I have the choice of having all pictures stored at a certain number of
DPI or certain dimensions? If so how? I have tried using the transfer
software that came with my Olympus camera. I have also used Windows transfer
wizard. I have sometimes used Uleads Photo Explorer to make very simple
changes to pictures only to find that if I use Photopaint to print out a
picture I get a warning that the resolution is too low. Can I easily store
all of my pictures at the most likely setting for printing? If changes need
to be made can they be done in batch mode?

Thanks in advance

A choice made, hopefully deterministically, by your camera when it
writes the JPEG headers. This has nothing to do with the content of
the image.

Who knows.

Moving the files around would not, one hopes, modify the JPEG headers.

Naughty photoshop.

"store" doesn't come into it. Perhaps you could modify them for such.

There are many programs which can modify JPEG headers in batch mode.

Thanks for that fellow Sandgroper.

I store images at the size it comes out of the camera, then edit them,
and save them elsewhere. Then re-edit them if I need to make them
smaller. I use Photoshop CS

Transferring images from the camera to the computer is just a file
transfer, i.e. copies the files. As long as you copy files they stay
the same as the originals, and you should always keep the originals
unchanged and make a copy with a different name to work on. If you
open the files and then save them, using either the same name or a
different name, they will have been changed by whatever the program
selects. Different programs have different defaults and usually an
option for changing the way they are saved, e.g., a program default
may be to save as an 85 percent jpg which would further compress the
image. Transfer from camera to computer is just copying files, so
they will remain the same as they were shot, e.g., 1600 x 1200. The
pixel size will never be able to be greater than what was taken by the
camera, unless you use programs able to interpolate (actually it is
extrapolate) the pixels. The ordinary user should never do this.
1600 x1200 will make good 5 x 4 inch pictures, and you may even get 7
x 5 inch pictures that have acceptable quality to you. You never
want to save the pictures at a lower pixel rate if you are going to
print them on paper. In printing, you select the physical size of the
print, and the programs automatically handles the printing dots per inch.

Some programs can save the images at low pixel rates for email and
either indicate actual pixel counts or quality. A fairly common
standard for sending email pictures is 800 x 600 ppi.

The low pixel warning is likely because you selected too large a size
for printing based on the number of pixels in the image. If that is
occurring when you try to print an image smaller than 5 x 7 inches,
you likely have inadvertently saved the image at a lower pixel count.
You need to further explore (pun intended) how ULead Photo Explorer
is saving your changed images; there are undoubtedly options.

It is easy enough to find out the pixel size by going to your file
directory and putting the cursor on the file (no clicking).

As for batch processes, the options vary widely by program.
Hope that helps.

They will be exactly as the camera pu tthem on the memory card.
Transferring them doesn't change them. This is a characteristic of the
digital system.

Not by just transferring them from the camera to your hard drive. They
are what they are.

Then they should be just as they wer eon the memory card. Nothing
changed.

???
I have no idea of what you did in Photo Explorer, and I have no idea
of what Photopaint expects, other than it is probably telling you that
what you did in Photo Explorer wasn't what you should have done.
What did you do in Photo Explorer?

You should *always* store your originals as originals. Never work on
an original; make a copy, and work on that instead.
Yes, changes can be done in batch mode, if your graphics app supports
that. Of course, in my case, I wouldn't want to do that, because each
pic is different, and will require different manipulation before
printing. Are all of your pics the same, such that a batch file will
optimize each one correctly for printing?
