Hi!
When I see such a print that meets my standards using the technique you've
described, I'll believe it. I've not seen anything approaching a 16x20 or
larger made from a 6mp Pentax camera that qualifies as "stunning" by my
standards. I know that there are plug-ins and software that supposedly
provides great results. I've yet to see the results obtained using such
software, therefore I am skeptical. However, based on the comments people
on the list make about the quality of the images posted here (mine
included, BTW), I think I may be a bit more critical than most, even with
my own photos and images.
Since grain, as I understand grain to be, doesn't exist in digital photos,
I don't quite understand the reference.
My personal impression is that if you don't go ressing up, you can get
very good quality 20x30 *cm* or even 24x36 *cm* prints from *istD. You
can get very reasonable (or is it just good) 30x45 *cm* prints...
Anything bigger than that would highly depend on the content. For
example, I have a shot of Tel Aviv skyline where digital fails
miserably. OTOH, I have a shot of reflection in the water in Hertzlia
Marina which will probably enlarge to rather big sizes beautifully.
YMMV of course.
However I reckon that if I were asked for paid work I would probably
bring with me two cameras - digital to do the tries and film to make
final actual shots.
