Thank you, Richard. I have a lot to learn. We nearly always have wind or at least a breeze here so focus stacking is only really feasible indoors.
I go out early morning when photographing native orchids, which in many cases only require a zephyr to make them move. Here, downunder, it is usually the calmest around sunrise and sunset. If there is a bit of a breeze, I use my hat as a shield, and being a dark leather it doesn't create a noticeable colour cast. However, it does help if you can control the camera remotely while shielding the subject from the breeze and/or sun, so you're not requiring to be in two places at once. I have seen one photographer in Tasmania using a light tent with the base removed to shield native orchids from the sun and breeze. Others use the cheap white umbrellas some use for studio lighting as a shield.
