http://www.photocourse.com/itext/care/care.pdf Professionals, just like the rest of us, use SLRs and even point-and shoot
cameras. However, when they move into the studio or explore some speciality
field, they often use other cameras. One of the main reasons is that they want
a larger image sensor with more pixels.


Some professional cameras, including this medium format Hasselblad, are
one-shot models that work just like your digital camera. When you press the
shutter button the picture is taken immediately.

Other professional cameras, such as the Linhof view camera shown here, are
converted to digital by the simple addition of a digital back that replaces the
traditional film holder. Some backs work like scanners. When you press the
shutter button, the digital back scans the scene a line at a time building up
the image line by line. Some capture the image in a single pass, others make
three passes—one each for the red, blue, and green light reflecting from the
subject. These cameras are slow so they can’t be used with moving subjects or
with strobe lights.
