You had better let Moose Peterson know about this problem ASAP since he has been shooting and publishing wildlife and nature photos with a "lowly" 2.7MP D1H for a couple of years now. I'm sure if image resolution presented such a serious limitation for his business that he would have switched to at least to a D1x at some point. Seriously, the 6MP images from the D100 (and the D1x for that matter) are perfectly adequate for a full spread in a magazine.
This is mine kind of work (layout). If the photos are of good quality there is no problem. I have seen good spreads even from Fuji S1 (3MP in-camerainterpolated to 6MP).

I think I follow you. But I wonder if you could flush this point out a little bit.
I will try (hope my english is good enough). If you look on a photo in a magazine or newspaper with a magnifyingglass you can see the little color rosettes that makes out the picture. The size of those sets the limit for the percieved quality of the photo. The size is measured in lines per inch. Magazines usually uses 133, 150 or 175 lpi, newspapers typically uses 85 or 100 lpi. Printers have a rule of the tumb that says that the digital file should have twice the dpi as the used screens lpi. More than that wont practicaly be noticable because the size of the rosettes.
You specifically stated that you were worried whether the resolution of the 6MP D100 would provide adequate resolution for Nature/Wildlife photography. I correctly pointed out that Moose Peterson uses a 2.7MP D1H camera and that 6MP is perfectly adequate for full-page spreads in magazines.
It is a pretty common misconception that PPI and DPI are the same, and while with some printers (Dye-Sub for example) they can be, they aren't necessarilly equivalents.What would be the difference of the dpi and ppi in Photoshop?Little nitpick - the PPI (not the DPI) resolution should be twice
the lpi
are the same, and while with some printers (Dye-Sub for example)
they can be, they aren't necessarilly equivalents.
A pixel is a picture element that contains the full range of
colours that the device can represent. The resolution that you set
in Photoshop is the numbers of pixels per inch. A dot, on the
other hand, is the fundamental unit that forms an image on a
particular device. On a printer that forms shades using dithering
(eg laser, ink-jet, etc.), a pixel consists of a multitude of dots
generate the full range of colours a variable number of these dots
- each dot is basically a droplet of ink/toner, and in order to
are layed out. In a printer that fully relies on dithering to
represent the range of colours, the number of dots per pixel
determines the number of shades it can produce. For example,
Epson's high end printers have ratings of 2880x1440 DPI, however
they can only deliver a resolution of360x360PPI.
Hope this helps

Most magazine photo editors will request 300 dpi digital originals, regardless of the line screen the magazine uses.
Sports Illustrated has been running double-trucks (two-page spreads) in the Up Front section from digital cameras for almost a year now. While I can usually tell the digital from the film (look at the noise patterns--at the higher ISO values used in most sports photography, you'll see distinct color noise in the digital shots), most of the world hasn't even noticed.
