World's Largest Photo taken with 645D
Lens: Pentax 300mm f/4 Camera: Pentax 645D Photo Location: Las Vegas ISO: 800 Shutter Speed: 1/125s Aperture: F9.5 
Posted By: Bill Bailey, 05-11-2011, 06:50 AM

I posted this in another thread and someone suggested I post a dedicated thread on this image so here it is.

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 click image or link below:

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 -

Bill Bailey

thx guys - a LOT of work goes into this in all phases - pre-production, production and post production. Then you have to hold your fingers crossed for good weather. Here the winds preventing me from making this image as large as I would have liked but we'll keep trying. With 4,000 images shot to pull this one off it won't be log before I have testing the 50,000 shutter limit of 645D.
After moving from the D3X to 645D I am amazed at the difference in quality and especially the overall tonal quality including the extremely low CA. There was a small amount of vignetting however on the lens (hence the banding) so next time I'll know to provide for more overlap.

thx
Bill

Bill,

This is just awesome! I can imagine the amount of hours you must have spent just on the PP

thx Dave - this will be a real test to Pentax as well to see how long the shutter will really last before needing replacement. Curious what the tell tail signs would be has it nears the end.

Bill, that is a awesome shot with so much dedication behind the scenes. Looking at the different hotels, I have lost money at every one. It is safer for me to view this from long distance than there in person. Great job, enjoyed the view. Bob

Hey Bob - I can relate

Images like this really captivate an audience. Like looking at a city through high power binoculars. Just in 4 days the image has seen over 5,000 views. Another testament to the quality of the Pentax 645D - it lures folks in. And now with over 150 snapshots you can really see Las Vegas in a different light - literally without having to try and find stuff yourself.

Prints this large would typically be printed in multiple sheets with overlap as if to paste onto a wall. A more practical solution would be to do multiple smaller sized "framed" prints and hang side by side to fit an area. The beauty of these super sized prints is you can reduce to fit while maintaining quality with the incredible resolution.
