While true, it was one thread where we were having an exchange
and you created a mosaic with extreme depth of field that demonstrated
that one could do the sorts of things I do with 4x5 that inspired me to
try the "real test." So in that sense you did break some new
ground in this field (at least for those of us in the newsgroups).

Well, I doubt that. I'm still crawling up the learning curve.

I need a new computer. The image that will be the focus of
my article is a 57 (or was it 59) frame mosaic of 8 megapixel
images with extreme depth of field. It took 14 hours for ptgui
to create the 5.8 gigabyte photoshop file with layers (on a
Pentium 4 1.8 GHz machine with 2 gbytes ram and 800 GBytes disk). The
layers were critical for blending the various focal points throughout
the image. The resulting image is something like 15,000 x 10,000
pixels (16-bit). And those digital pixels (from a 1D Mark II)
are great compared to pixels from a film scan at the same size
for a 4x5 transparency. I'll get a new machine in a month or so.

I see fewer restrictions with digital mosaicking than I do with LF.
But mosaicking has some different restrictions, fast time being one
of them (e.g rapidly changing light on the scene). LF suffers
too often from wind. On my recent Colorado wildflower trip,
I would have gotten very few 4x5s compared to the many digital
mosaics I did get.

Agreed. It will be a while before I get the article done. I have
3 professional paper to complete asap.
