Firstly - this is the second exact copy I have got from your original
post reply - hasn't this been happening before to some folk?
I think we are losing the thread or essence. I think the original query
was a 5Mb pic against a 3Mb pic or something like that.
If one was interpolated the resolution would have been faked but Ok.
Generally jpg's are compressed and thus pics get smaller - it a loss
making squashier. Canon 300D & 350D use very little compression in
their JPG's at max resolution but when I save them in PaintShop pro they
reduce by about 35% from the camera size. I don't know if PS does the
same or if psp files are compressed. That is one reason why professions
use RAW format in the size of a football pitch but the problem is RAW is
not a universal format and each manufacturer has their own version of it
so I stick to JPG for general work and TIF full colour separation for
publishing.
