At 10.02GB this is the worlds largest multi-image composite to date taken using the Pentax 645D.
Pixel Dimension (1"= 72dpi): 218,944 x 45,776 pixels
Print size approx: 253 feet x 53 feet = 13,409 sq feet (77 meters x 16 meters = 1,232 sq meters)
Equivalent to 6,390 8x10 prints.
The image is comprised of 616 separate RAW images (44 columns by 14 rows) with 25% overlap between images.
The lens used was the Pentax 300mm prime f/4.
ISO: 800
Exposure: 1/250
F-stop: f/9.5 (the sharpest f-stop with this lens).

The images were shot from the 61st floor of the Cosmopolitan Hotel and Casino in Las Vegas. Winds were heavy (est 20-30mph with gusts to 45mph) hence the high ISO to get a bit faster shutter speed.
I did several mosaics over the weekends shoot totaling close to 4,000 images. Due to the winds the mosaics shot at longer focal lengths were unacceptable giving us excuse to return again in the future - 3 times the charm

.

The above thumbnail image is approx 05% the size of the original. To enjoy the full detail and of this super high resolution gigapixel image please visit:
Bill Bailey's Las Vegas Town from the Cosmopolitan

I used a Nikon D3x 400mm focal length lens on previous gigapixel images shot from this location. The tonal qualities of the 645D combined with the optics of the lens is far superior. The image almost has a 3 dimensional look to it.

I want to thank the management of the beautiful Cosmopolitan Hotel & Casino in Las Vegas, with a special thanks to Kristina Kolk, for helping us to organize and make this happen on such a busy Spring Break weekend. They truly went out of their way to accommodate us.

Enjoy -

I think this deserves a separate thread, Bill

THats incredible. The crazy part is, if you go to the site, you can zoom to street level. Close enough to read vehicle license plates!!! Holy Cow! Great work!

Who's looking at license plates. Check out the people at the pool

The life guard and the guy next to him (our right), ha.

I think near sunset when lights are on and there is still ambient light would make for a more interesting shot. I don't know how long it takes to shoot all those, however.

Dang! Forget the lifeguard! How about the headless woman on the far side of the pool!

Better still, on the sidewalk by the restaurant at the base of the eiffel tower wannabe, are two people merged into one. The top half of one person is transposed on the bottom half of another and each is walking in the opposite direction.

Cool picture. Despite of that woman at that pool without a head there's one guy who has three arms.
Uh, Las Vegas! Everything's possible.

More from the P67 and 105/2.4, this time with Portra 400 at EI250. Really amazing film, the grain, sharpness, and color never fail to astound me. I'm going to try pushing it to 1600 next time.

Very nice, both of them - perhaps not following the rules, whatever they are, but that's healthy! Thanks for sharing these.

Yoohoo! Got my first roll back from the lab, processed and scanned. The pictures aren't much to be excited about (nothing like that gigapixel shot...) but they are exciting to me because that my first ever roll of film in this camera. I was shooting with a P645N and an 80-160 and 200mm manual focus lenses, on portra 400. Here are a couple of shots from that roll:
