Walt said nothing about wind blown trees or pumping up the ISO. When I shoot in deep woods, I am usually shooting something near ground level to shoulder height. So if the trees are blowing I don't really care. I just have to be concerned about using slow shutter speed due to the light and my desire not to increase the ISO for the reasons you mentioned. So I will use a tripod and remote. I might decide to use multiple shots to increase DR, or multiple shots with horizontal offset for stereo so those are other reasons I'll use a tripod. That's when I'll use MLU. I can't see using MLU for handheld photography.No hard feelings here Walt. As I said in my last reply, I respectfully disagree.
I would respectfully disagree. If there is so much motion in the scene [such as wind blown trees] that you are pumping up ISO to get a fast enough shutter speed to minimize the blur from that, then the purpose of using a tripod and MLU is defeated and you might as well handhold the shot.photonut2008 wrote:
Here's a hint, the situations where you want the former are mutually exclusive to the situations where you want the latter.
I can think of a few shots where you would want both and cross your fingers too. Around twilight, mostly, or in a deep woods, for instance.
If I do handheld macro in those circumstances, I will use a flash to freeze camera and subject motion, so I don't use MLU.
If I am doing closeup (approx 1:4 mag) shots of flowers under natural light, I'll typically use a tripod to help with composition. I'll stop down a lot

Take your forest example for instance. Pumping the ISO up reduces DR, thus you are not shooting optimally by doing so. Now you may say that you are trading something in exchange for the reduced DR and increased noise, but then you get back to the question of why you bothered to use MLU under those conditions in the first place.Is that the only condition under which those settings are used? For all photographers? The previous poster also was limited in his vision of the scope of photography in saying never to the combo. Which is an absolute, as in never for any photographer. I simply said that never was wrong and sometimes was right. Some shots would use the combo.
Ah, but you are arguing in the abstract. You can "think of a few" situations where you want a fast lens, a high ISO, and a slow shutter speed that tangibly benefits from MLU. I can imagine them, but I would do everything I could to get around some part of that (starting with reducing the high ISO).And here you are with just one out of the galaxy of possible uses.
The OP was about MLU. Anyway, it's not the one approach that I would select, but the one approach I would not select that is the issue here. For me MLU, and a fast lens with high ISO are mutually exclusive -- YMMV, but I have seen far too many examples where the photographer cranks up the ISO in lieu of more effective solutions.I'd not even agree that handholding is necessary. Or even that you want to remove the motion. There are many ways to compose such a shot. You have chosen one.
