I've just posted some shots of our recent Barcelona visit at:
http://www.iol.ie/~corkflor/
As I was getting overwhelmed by proof prints, I instructed my
friendly photo processors to simply develop the film and provide a CD
with a reference print. This means I can review what I've got very
quickly on the Mac, find the average 3 or 4 keepers per roll, and
scan the relevant negs to produce decent prints.
In other words, my ancient film Leicas are being used in a more
direct digital way, and my flatbed scanner won't get much more use.
But to prepare shots for the Web, I simply took the hi-res versions
on disc, cropped, corrected and re-sized them, and then saved them as
a small 'lossy' JPEG.
The original hi-res files are around 700K, which compares poorly with
the 20Mb+ available from a neg. But for the Net where you're
publishing at around 90 p.p.i., this is not such a problem.
My question is this: the hi-res disk files have a JPEG (jpg) handle,
and received wisdom is that quality deteriorates rapidly if you try
to re-compress an existing JPEG. So are these hi-res files really
JPEGs?
I took a deep breath and saved the adjusted and resized PS files as
small JPEGs, and, as you can see, the results seem pretty good - in
fact more or less on a par with what I would expect from a Net-ready
JPEG where the original data came from film. Am I missing something
here?
All explanations gratefully received.
Anyway, as it works for me, this route will save an an awful lot of
trees, not to mention reducing my processing bills drastically.
Best
Alex
