They are coffins from the Bronze Age used for burial practice, similar to the Tombs of Egypt in that sense.
Answer:
The first option
Explanation:
I already explained on the other question you've posted; make sure to check that one!
Pinhole photography is a very basic and different form of
photography than you are used to. You must think of the photograph you
are creating not of the equipment. I don’t believe you can get a bad
picture with a pinhole camera. The exposure is not that critical. You
are dealing in a different time frame with this type of camera. The
difference in a 10 to 25 second exposure is less than one 1 stop and the
difference in 25 and 60 seconds is again 1ess than one f stop.
Reciprocity factor is working here in the films. In a regular camera and
a modern high speed lens. these times are equivalent to 1/125 sec. to
1/60 sec. and 1/60 sec. to 1/30 sec. (not much time difference). So if
you are off on your times somewhat, it probably won’t show in the final
photo. Every picture is a time exposure. All motion will be a blur, even
very slow motion. Fast moving objects just don’t show up in the film.
So have fun with a pinhole camera and enjoy a different form of photography!
