Erez Marom Explains Focus Stacking in Macro Photography

Not fridge, but L2N or similar stuff. Or glue.. I think both are very ugly things to do.

But in reality, what you need is reasonably high ISO, lens stopped to f4 or so and camera with high FPS. For example Canon 1D series was pretty good for this + manual focus lens on tripod.

Or if you have like 180-200mm macro lens, you can simply stay far enough to not disturb critters at all.

Macro photos doesnt need to be made with “true” macro lens..

Truth to be told, sometimes Im amazed how they pulled of such shot. 😀
