Ever wondered how your flash tube looks like when it actually fires? It looks like a space station. And not those hi-tech preppy stations too. It looks like what our great, great grandparents would have build for a space station.
Photographer Hal Harrison took this to the test. Shooting a strobe tube is actually not an easy task. You want to keep maximal Depth of Field, but in the same time you need to get lots of light, nail focus and deal with every aspect of macro photography.
Hal’s solution? Use a pinhole camera. Or rather a pinhole adapter for his D800. Hal tells DIYP:
[…these photos] were taken with a pinhole “lens” for my D800. There is no preview, you just place the camera face near the flash tube and look at the image review after taking a shot to make adjustments. These were taken at 200th sec (irrelevant, save that it is below sync speed) and ISO 50. There is no aperture adjustment for pinholes. The hole is both the “lens” and the aperture itself.
Of course the ultimate DOF of the pinhole eliminates the need for focus stacking or any other focus problems.
