FlexBody, ArcBody, and PC Mutar for Digital Imaging and Film Photography 227
Exposure with the PC Mutar
Because the PC Muter is a 1.4 converter; exposure needs a one-stop increase unless the expo-
sure determination is made through the lens and converter. You will also notice a darkening on
the focusing screen when the PC Mutar/lens combination is shifted away from the 0 position.
This darkening is only on the screen and not in the image. But you must take a meter reading
with a meter in the camera or prism viewfi nder at the neutral 0 position before you shift.
Photographing with the PC Mutar
Vertical lines are recorded straight and parallel when the image plane is parallel to the sub-
ject. Start the photography by leveling the camera. Loosen the PC Mutar shift control lock and
shift the PC Mutar up or down until you see the desired image area on the focusing screen
(Figure 13-11).
Figure 13-11 PC Mutar and ArcBody applications. The PC Mutar combined with a 50 mm lens
produced a good architectural photograph with perfectly straight and parallel verticals (left).
The ArcBody produced the same results in a street scene in Germany (right). (Photos by
