I know a publisher of a highly image oriented aviation magazine who uses
digital in a lot of his printed material, incl. full page and covers,
otherwise he specifies Velvia.  He's done a lot of his own work from a
Canon 10D for the mag.

(I bet he's moved up to a 20D in the meantime since I've chatted with him).

http://www.verticalmag.com/issue02/ cover was shot on a Canon 10D.
I have the digital image but I can't send it to you. (C).
3072 x 2048 pix.  In the original you can pick off pretty good detail
from the drilling platform in the BG.

Cheers,
Alan.

I heard that 5 megapixels is the minimum most publications will accept.  Any
more would be icing on the cake.

Yesterday I was watching a photographer on TV taking some shots with a Nikon
DSLR in a studio setting with full strobes.  Not sure which model it was,
but every time he took a shot he's check the LCD on the back of the camera,
and I could see it lit up.  That's why I know he was shooting digital.

I would say it depends on the magazine, but as pixel counts go up they will
all eventually cave.  And they are already making medium format digital
cameras.

There was a big debate here (or rec.digital) about Arizona Highways
refusing 6MP digital images. They print tabloid sized (small newspaper)
double page photos so maybe that was near the edge of usability but also
they just were used to large format & resisting a new workflow. That's
nice that they can keep those guys employed but I don't think it's at
all typical of most magazines, more like an example of a last holdout.

Ken,

For some 6 isn't even close. This from Webshots...

Specifications - Transparencies and Slides

For best reproduction quality, we prefer original slides, but we accept
duplicate slides for initial consideration (make sure you indicate they are
duplicates). To ensure their safety, slides should be placed in plastic
slide pages and each should be clearly labeled with your name and a caption.
Please include specific subject and location information. Loose and/or
uncaptioned slides will not be considered. Please do not submit unless you
have a minimum of 60 images (150+ optimal). Note that due to desktop format,
we prefer horizontal photos to vertical.

Formats accepted: 35mm slides + larger sized transparencies (i.e. 4x5, 6x7)

Specifications - Digital Files

Although we prefer slides, we do accept digital submissions on CD-ROM.
Please note that we require a final resolution of 5400x3600 @ 300 dpi. Few
digital cameras are capable of reaching a resolution that high, but Webshots
will consider images taken with cameras 11 megapixels and higher. Please
save the images in .jpg format at high quality level 10 (if saving in
Photoshop).

Submit all CD images at 1600x1200 @ 72 dpi and also include one image at
5400x3600 @ 300 dpi so we may better evaluate your scan quality. This one
should be the best representation of your work. All images must be
artifact-free and color corrected to be considered. If you scan your own
work, please note that you'll need a scanner that can "optically" produce
files at a minimum of 4000 dpi. Images interpolated more than 30% will not
be accepted.

Regards

DM
