A week ago Joe McNally tweeted about a new cool campaign shot he did recently that will be launching this fall. There is some more interesting information on his blog: Mr. McNally will have a new exhibition at the Time Warner Center called "Faces Of Ground Zero: 10 Years Later" that will open on... August 24th, the same day Nikon will have its new product announcement. The exhibition is sponsored by Nikon USA (and others) according to his last blog post:
"Shot this, along with a video interview with Bill, just last week. The interview, and the portraits open at the Time Warner Center at Columbus Circle, on Aug. 24th.
Exhibition made possible with the generous sponsorship of Nikon USA, Johnson & Johnson, JP Morgan, and friends of the collection."
It seems that video was an important part of this project. If there is a new Nikon D4 on August 24th, Joe McNally is probably the best person to make the promo campaign.
FYI: Joe McNally did the Nikon D3 promo:
