Hi,
I want to scan some color pictures, size 4x6 inches, printed by a lab.
My scanner can be set up to 9600 pixels per inch, but the default (and also
automatic setting) is 200 ppi.
What is your suggestion about it? It may seem a dumb question but I see the
file size increase a lot increasing the ppi #. Also I get larger pictures,
but at a certain point (I would say between 200ppi and 300ppi but my eye's
not an expert one) I start seeing losses of quality in the pics.
File sizes are:
200ppi: 287 Kb
300ppi: 698 Kb
600ppi: 2,1 Mb
Let's say I don't care how the file size is, at the moment. What could I do
with a larger picture if the quality is proportionally lower?
I mean, if I scan at 200ppi, then I resize the pic up to the dimension of
the file I get at 300ppi, do I get the same quality? A lower one? A higher
one?
Please help me to clear the clouds.
thanks
