Hi Neil
Great newsletter, as always. I look forward to receiving it as it always has great info or tips to improve what I do. I am getting amazing results with on camera flash now, so thanks and thanks again!!
One question I have which I hope you can help me with. I have a Nikon D3S and I've been asked to shoot some commercial images that the client wants to blow up to A1 & A0 size posters. Do you happen to know what the D3S resolution can be blown up to before it runs out of gas?
Thanks a bunch

Comparing the metric print sizes:
A0 size = 1189 x 841 mm / 46.8 x 33.1 inches
The Nikon D3 sensor is 4256 x 2832 pixels.
If you print with 300 pixels per inch, then you can get a print that is (4253/300 = 14 inches) x (2832/300 = 9.44 inches)
So you can natively print to 14x9.5 inches without enlarging the image, when you print at 300 ppi
If you settle for 230 ppi ... and then I did a google search ... and found this site which explains it even better:
http://www.design215.com/toolbox/print_guide.php
if you print to 150 ppi then you can natively print to 28.6 x 18.6 inches without up-rezzing.
As they mention there, viewing distance is everything. People are unlikely to scour a poster in a shopping mall for detail.
so you could still up-rez the file to get to the sizes you want.
Ultimately, it seems like renting a D3x might be the better choice here.

I frequently print 20x30 and even 24x36 from my D200. No photographer would ever mistake the results for images from a medium or (drool) large format camera, but as long as the clients are happy...
