m 4/3 fantasy work
He's got fully adjustable stage where he shoots this. Stage that tilts, shifts and allows to mount flashes.
The main glass is Raynox-250 macro adapter. He doesn't tell what lenses he uses.
The most important tool is patience. He is training ants. He reads books about ants.
These are not collages. He does multi-exposures though. He started with several exposures, now he can get the shot with one, maximum two exposures.
Other than that he only uses Photoshop to increase contrast, saturation - to make photos look like a fairy tale.
The patience didn't come for free. The guy had a spine trauma 7 years ago. He is limited in movement. He's got ant hill 50 meters from his house, that's where he shoots this.
Got this from his interview. There are more photos. Two photos with him are made with Samsung compact (Samsung WB650, 1/2.3" sensor) because DOF is wider. Normally he shoots with m4/3 and F22 aperture and has to scale down shots because of diffraction.
