A 35mm SLR is a camera designed primarily for handheld photography, to “grasp life hot”, for dynamic work, but also suitable for special tasks, like for example. for macro photography, reproduction photos in the laboratory, for microphotography.
If it is used in these special fields, sometimes auxiliary devices are needed. We omit interchangeable lenses here, which will be discussed separately, now we will deal with the auxiliary equipment in turn.
TRIPOD
Although in amateur photography most of the photos are taken handheld, in practice you cannot do without a tripod. First of all, photos, even snapshot, but with a longer exposure time (below 1/60 s, exceptionally 1/30 s), require a tripod, if we want to be sure, that they will not be moved. Similarly, photos of interiors with exposure times lasting sometimes a few or several seconds, photos in artificial light, reproductions of paintings, photos at night, still life photos, technical photos, industrial and scientific, microdocumentation and much more, no longer belonging to amateur photography.
The tripod should be strong enough, not wobbly, so that you can take photos "on time" (using the drain hose), without fear of camera shake.
For work at home, a massive one is best, wooden tripod with tilting and rotating head, guaranteeing certainty, even when using a heavy DSLR with a long focal length lens.
Such a tripod also provides invaluable services for portrait photos, even with shutters or with a vacuum tube. You can then focus your full attention on the facial expression of the subject, looking straight at her, not through a prism viewfinder.
On the other hand, a lightweight tripod is suitable for outdoor photography, multiple, although not guaranteeing stability, but allowing timed shots at slow shutter speeds (np. 1/2 s — 1/30 s). It is also indispensable when photographing flowers in the field, mushrooms etc., when the focus setting has to be very precise, difficult when working with a camera in hand.
Finally, there are replacement devices: rarely used "unipods", i.e. a kind of one-legged tripods to be rested with the end on the ground or on a thong slung over the neck, tripod clamps that can be screwed to furniture, handrail etc. or screw into a tree trunk and short "table" tripods (ok. 30 cm) legs, suitable for table setting. They are especially useful when photographing small objects, np. small plants in the forest. Then, if the camera does not have a replaceable focusing screen instead of a prism focusing screen, the photographer must lie down on the ground, flat – on the belly, to look inside the prism viewfinder.
