Selecting a Digital Studio Camera
The highest quality digital images are captured with digital studio cameras or a removable digital back for a medium format or view camera. Digital backs, containing either linear or matrix arrays, simply replace traditional film backs. Used for catalog and advertising work, these cameras come in three main classes.
The choice of method for a given capture is of course determined largely by the subject matter. It is usually inappropriate to attempt to capture a subject which moves (like people or objects in motion) with anything but a single shot system. However, the higher color fidelity and larger file sizes and resolutions available with multi-shot and scan-backs make them attractive for commercial photographers working with stationary subjects and large-format photographs.Single Shot
Single-shot backs only require one expsoure. Single Shot capture systems use either one CCD with a Bayer filter stamped onto it or three separate CCDs (one each for the primary additive colors Red, Green and Blue) which are exposed to the same image via a beam splitter.
Mega Vision
MegaVision single-shot backs for medium-format cameras include the S3, S3Pro, S4 and S427. Designed for use in studio and on location, the compact design of these backs are excellent for professional photographers whose work includes portraiture, fashion, wedding, product and corporate.Phase One
The H 25 is available for Hasselblad 6x6, Mamiya RZ and a wide range of 4"x5" view cameras. Its very high resolution combined with a broader CCD sensor, very fast capture rate and amazing quality at long exposure times makes the H 25 absolutely perfect for the demanding commercial photographer.Multi-Shot
Multi-shot backs utilize a sensor that is exposed to the image in a sequence of three or more openings of the lens aperture. There are several methods of application of the multi-shot technique. The most common originally was to use a single CCD with three filters (once again red, green and blue) passed in front of the sensor in sequence to obtain the additive color information. Another multiple shot method utilized a single CCD with a Bayer filter but actually moved the physical location of the sensor chip on the focus plane of the lens to "stitch" together a higher resolution image than the CCD would allow otherwise. A third version combined the two methods without stamping a Bayer filter onto the chip.Scan
The sensor moves across the focus plane much like the sensor of a desktop scanner. These CCDs are usually referred to as "sticks" rather than "chips" because they utilize only a single row of pixels (more properly "photosites") which are again "stamped" with the Bayer filter. These cameras require you to use "hot lights" and other continuous lighting systems.
Better Light
Better Light's high performance digital scan backs are ideal for jobs that demand critical detail and color accuracy, and for projects where the size and the specs of the reproduction process require large original digital files.
