Thank you for the above article. It was of interest.
One question as I am not fimilar with multishot backs. In 4 shot mode on the eMotion 54/75, what would be the total time to capiture an image if shutter speed is set to 1 second? And, I presume you only press the shutter release once. Or, do you have to cock the shutter and trip it 4 times? (Digitar lens)
the eMotions are single shot backs designed for on location work, with display, internal storage of 6 GB hard-state memory, CF-card slot, fast shooting rate of 0.9 sec/frame, etc ...
The multishot backs are the Sinarbakc 54 H (22 MPx) and the new eVolution 75 (33 MPx).
In 4 shot mode the software controls the 4 shots automatically and the exposure is released in so-called slave mode i the captureshop software. The 4 shots are taken consecutively and one can set a "delay" between the shots to let the power packs recycle within the shots, for the next one. The actual exposure time of each shot is the time you are setting on your camera shutter, being it a MF or a view camera. Acually this process is very fast, basicall 4 times the time of single shot.
From this one gets a full and true colour file, without any interpolation like one has with single shot backs. Beside all the quality advantages, such a 4-shot files can be opened as well much much faster than a single shot, simply because there is no interpolation process included during opening.
I hope this answers fully.
