📷 Photographing and Filming Bees

A 3D macro-photography rig aimed at a bee on a flower, showing exactly how aperture, focal length, subject distance and lighting setup change what stays sharp in the frame.

🔬 What It Demonstrates

The near/far depth-of-field limits are computed from real lens optics (hyperfocal distance, circle of confusion) and rendered as translucent green (sharp) and red (blurred) slabs around the subject.

🎮 How to Use

Adjust aperture, focal length and subject distance to watch the in-focus zone stretch or shrink, and switch lighting setups to compare natural backlight, flash fill and flat overcast light.

💡 Did You Know?

At close macro distances the depth of field can shrink to just a few millimetres — often less than the width of a bee's thorax — which is why apiary photographers stop down or stack focus.
