19. Infrared Photography
In infrared photography, some adjustments must be made in the
focus in order to retain sharpness on the film, because the invisible
infrared rays are longer in wavelength than the visible rays used for
focusing. For infrared photography: -
1. Use an R filter or equivalent with an infrared (black-and-white) film.
2. The red-colored line, next to the green-colored distance index, is
the infrared index.
3. After focusing in the normal manner, re-set the distance indicated
by the green-colored distance index to the infrared index, by shifting
the distance ring.
4. Follow instructions enclosed with the infrared film and filter and, to
be on the safe side, make several bracketing shots. In general, more
exposure rather than less seems to be a safe guide.
20. Flash Photography
A. Always use flash cords with a standard PC type plug. When
detaching the flash cord, grip the plug firmly and pull it out straight
instead or using a twisting action.
B. The lens shutter of the Zenza Bronica ETRS has a X-setting for flash
synchronization, which means that electronic flash units will synchro-
nize at all shutter speed settings, up to the fastest 1/500 second.
Thus, it is very convenient for taking shots in daylight, which require
flash fill-in, too.
21. Multiple Exposures
A. To make multiple exposures, rotate the film-winding crank (to
advance the film and cock the shutter) and then turn the multiple
exposure lever in the clockwise or arrow-indicated direction, which
will expose a red mark. When set in this manner, the shutter can be
released and cocked any number of times, without advancing the
film.
B. Upon taking the multiple exposed picture, be sure to return the
multiple lever back to its vertical position and cover the red mark.
Otherwise, there will be additional multiple exposures on the same
frame.
