One roll, one lens
I took one camera, one 35mm lens and one roll of 36 exposures on a three-day trip. No phone photos allowed, except for maps.
Having only thirty-six frames changes how you look at things. You wait for the light, you take a step to the left, and most of the time you do not press the shutter at all.
Out of thirty-six frames, nine were worth printing. That is roughly my average, and I have stopped being disappointed by it.
