Someone wrote, "Go big, go REALLY BIG!" in a forum post, and that describes the LS911 well. Also...
Other camera companies say that bigger is better; it is true when it comes to medium format-type sizes, and even more true with large format! The LS911 is the biggest!
A large sensor area gives a 3D feeling to images with great tones. Also big pixels.
One shot means the whole sensor is read all at once. Scanning backs have to read parts at a time, which are not useful for subjects that move, and they don't work well with strobes.
Use the electronic shutter at speeds of up to 1/26s. Allows using lenses without shutters. Makes taking images much easier and simpler with the WiFi-based command interface. An external LC shutter will be available later with speeds as fast as 1/500 sec and precisely adjustable.
Images show camera mounted with a Sinar Front, either a Fujinon lens or an A T Thompson lens, and on a Ries tripod. This is the final design of the LS911-V camera.
Excellent support for IR and UV, since there is no blocking filter in the camera.

Optional full frame down sampling to 1280 x 720.
Stereo sound recording inputs
Video output options 16 bit TIFFs, DNGs, CinemaDNG, JPEGs, h.264
Huge sensor size capture allows solid video with great tones.
The LS911 allows three decimal frames per second control.
The large sensor LS911 uses a rolling shutter. Rolling shutters can produce distortions, but the LS911 handles it well. See the test videos.
Control of the camera is done through an HTML interface. PCs, tablets and phones may connect to the camera's WiFi connection. A guest account allows users with a PIN to browse and download images on the camera. A wired Ethernet connection may also be used for camera control and image sharing.
LargeSense cameras can import your PhotoShop actions and apply your curves to the linear images the camera takes. These are applied to the JPEG images saved and shown as preview images, as well as being embedded in the raw DNG images.
You can set the electronic shutter with fractional, ms, or seconds.

An LSR1 program will allow further processing of the images.
LargeSense will keep updating the interface software for all models of cameras. An abstraction from the hardware allows quick updating of the functions and user interface.
Sensor size is an important component of image quality. It brings out the "magical 3D quality" in images, and better tones.
LargeSense cameras have large pixels also.
The rail for the LS911 is a 1-inch rail T Slot profile made by 80/20 Inc. Part# 1010-S. Users may order their own lengths. A 2- and 3-foot rail are included with the camera. If the rail is long or a heavy lens is used, then additional support would be required.
Some people are interested in having the camera to be just a digital back that fits on an existing camera, but due to the size and weight of the digital part it can't just fit on an existing film camera. The bellows can connect to the front of a film camera. Currently, the bellows are designed to fit a Sinar F2 housing.
The base ISO is rather high, but it is a good feature as large format users tend to stop down lenses a good bit, such as f/64 or f/128. Though for outside, an ND filter might be needed in bright light. Not tested on stars yet.
LS911-V Video and still capable 9x11 inch digital camera
LS911-S Still only 9x11 inch digital (The still version is delayed due to cost and time, but if there is enough interest, a still only version could be made.)
LS911-C Color version that can do video. Please inquire for the extra cost and lead time.
Rotating sensor is planned later if there is enough interest. This option adds 25% more weight but could be useful in a studio.S - still photos only C - color M - monochrome R - rotating
The sensor has glass bonded to it. In front of that glass is another plate of glass which protects the sensor glass, called the Front Sensor Glass. The front sensor glass can be configured for visible light only, or to allow all light.
During ordering, the type of glass can be picked. Afterwards the glass can be changed but requires disassembly of the camera.
LS911-Glass-FB Full Band. Allows taking NIR or UV images. Requires filters.
LS911-Glass-VB Visible Band pass. Blocks NIR and UV, allowing only visible light. The advantage is that every lens is ready without needing a filter.
Body color can be customized. The standard body color is Prismatic Powders Desert Red Wrinkle.
When ordering the camera any powder coat can be chosen for the body. A sample of possible powder coats for the body: Prismatic Powders
Ready to sell / demo! Please contact us if you are interested.
The final body is mostly finished. Getting the camera software ready to give demos.
Some updates for the New Year.
The final prototype LS911 case is going into powder coating. The case and a more final software should be ready in February.
