Re: JPG File Size

You seem to be mixing up the concept of dots per inch and pixels.
Pixels are a measurement of what is seen on your monitor,
and Dots per inch are a measurement of what is sent to your printer, (the 
one by your desk (300-600 dpi) or to the printer with the huge offset press 
(600-1200 + dpi)

Since your monitor is capable of no more than 72 to 96 pixels per inch (on 
an 800 or perhaps 1024 pixel screen resolution) there is no reason (unless 
your are working for the press) to scan at more than say 100 or 120 dots 
per inch.

If you scan at 600 dots per inch, that one inch will take up most of your 
screen, and you will need to scroll every which way to see it. And the file 
will be huge.

Scan at 100 dots per inch and you will get about eight inches across your 
screen and the file will be smaller. Yes the quality is not as good, but 
your screen is not capable of better quality. Then when you save it as a 
JPG,  it gives you the choice of higher or lower quality resolutions, 
choose the lower resolution settings for normal scans, and reserve the 
higher quality for photos representing fine art.

If you will use thumbnails, make smaller prints in Adobe, and then a larger 
print for the target print. If you use the target print for your thumbnail, 
and then use html to constrain the size, you still have to download the 
large files and they will be distorted by the local reduction in size.

Hope this helps you a little.
