Hi Nick,
nicely shot video, but I for one do find taking close ups without a tripod or monopod hit and miss.
Yes, me too.
For several years I have used a tripod most of the time to provide better control over composition and focusing, mainly using a "hands-on" tripod technique rather than the classic "hands-off" technique, where you line up the shot, give the camera time to settle and then use a remote release. That only works for me in completely, or almost completely still air. I use it when I can, but that isn't often.
It's only in the past few days that I have been working mainly hand held. I'm still in the stage of discovering its limits, and what circumstances are best for hand-held and what for using a tripod. And with hand-held I'm starting to recognise which type of shots are best using manual focus and which using autofocus.
I'm hoping that hand-held will become less hit and miss with practice. Like everything else, I would expect it to improve with practice, and indeed I think it's already happening somewhat. How far it goes though remains to be seen. I have to say though that I do like the flexibility and speed of working hand-held; it lets me be more responsive to changing circumstances and new opportunities that suddenly arise and may not last long.
There are some types of shots for which I think a tripod will always be necessary. I'm thinking particularly of early morning natural light shots of snails in motion. Because of the low light levels and the very small apertures I use, I end up using slow shutter speeds even if I bounce up the ISO as far as I feel is practical. Using a hands-on tripod technique lets me use slower exposures than would otherwise be possible. (Incidentally, the shots are then hit and miss for a different reason - whether they work or not depends on how much the snail, and in particular its eye stalks, move during the exposure. The exposures are often sufficiently slow for a fair proportion of the shots to be unusable because the eye stalks are not in focus, and for me that almost always means throwing the shot away.)
