For the record, these shots were taken in a Butterfly house. That is also the only way I would have had the patience to photograph them.
I tried the standard techniques used to shoot birds. Well, birds usually fly in a line you can follow. Butterfly’s ‘flit’ where ever they want or the wind blows. I needed a new plan.
Next I tried focusing where they could be expected to land. No logic in their flight that I could see. So again frustration.
Finally I just scrambled around different flowers with the shutter held down. I did get a few decent images. But not many.
How did people do this when they had 36 exposures on a roll of film?
