With the great variety of insect life which can be discovered and the complexities of identification it is often a case of one day sampling followed by a week of identification. But some of these guys are the real experts, who write the identification books, so they have a bit of a headstart over those of us who are just learning.
Regarding camera settings; my 'default' setting is aperture priority with F11 and Iso 400 then let the shutter speed find its own level. Although if there is obviously fast action in the scene I will switch to shutter priority but with the same 400 Iso. My default shutter setting is 1/640.
Those starting points mean I can usually get away with something acceptable if I need a quick response shot. 'Look at that' pick up camera switch on and click. However, when there is a little more time I can look around the scene then decide what are the potential problem areas and make a deliberate choice of starting point settings. Followed by a review of the first couple of test images and further refinement to the settings.
My problems usually arise when I make a conscious decision to change my adjustments, for example to a lower Iso, then move on to a different subject without reverting to my original default setting. So then, when that quick shot is required I can be caught out and end up with too low a shutter speed or something else not at the optimum adjustment.
Ideally, I soon realise my mistake after reviewing those first quick shots but, unfortunately, sometimes the opportunity for another more carefully thought out shot doesn't occur. Which was the case with these quick candid shots of the fly group members.
