of course when one plans beforehand to take pictures at some place and some time, adequate iso and optional tripod. But I often have a camera with me in the bag or in the car, and shot impromptu here and there without any planning.
all the pictures here were taken with hand held Bronica S2.
this september when border was open one afternoon I drove to nearby Värmland for some shopping, I had plenty of time it was a nice sunny day and I decided to wander around in the beautiful countryside, I had rolls of Retropan-320 and Lomography-400 in the car. At some moment I recalled the car cemetery at Båstnäs and drove there. This was not planned. As said it was a sunny day but the cars are under the shade of the trees.
a shot outside the forest, at 1/1000s with the Lomography 400:

but then inside the cemetery, this I had to shot at 1/8 s:

or this, at 1/15s:

of course the alternative was to push the film one or two stops, but then I try not to with Lomography-400 (avoid colour shifts). And this shots have got some bit of luminosity in the post-scanning negative to positive conversion, in fact it was somewhat dim under the trees.
other common occurrences with me, I am in the city for some errands, camera in the bag as usual. It's afternoon but by now mid-november, dark around 15:30, which is early, still I'd like to take some pictures...
Here, Retropan-320 was all I had in the bag, my ligthmeter was telling I had to push to iso 2500 (!) and yet use slow speeds. I didn't dare to push to 3200, and the manufacturer of the film has instructions for development at 320 or 640 only. So I had to enter unknown territory. I somehow estimated a dev time by diverse interpolations based on other emulsions, with Atomal-49, and got usable positives (scanned).
this at 1/15s:

couple other shots handheld with the Bronica S2, here at 1/8s, and the first one has in fact some softness, I breathed at the wrong moment when taking the shot

. Tri-X 400 film, sun is set but still casting enough light:

I really like the ergonomics of the Bronica, and the shutter button, the mirror flips down to the bottom which I believe causes less vibration and the weight of the body+back with regular lens and a prism is around 2,2/2,3 kg which provides some mass inertia absorbing some vibration. At least that's how I explain the ease of use at low speeds.
The opposite, a Moskva-5 is so light and the shutter button is on the top, that I always fear some slightly move of my hands.
