Closer to corals: A maco photograph of leather coral
I've started experimenting with macro photography of corals. In this particular case I've used Tamron 70-300 with MACRO function. It means taking a shot 95 cm away from subject. Well, this is tricky. Picture were taken with all external lights off. The only illumination comes from deep actinic lights (2x38W) Arcadia Actinics. I've used 1/30 sec shutter speed, EV +0.5 compensation of exposure, f/5.6 aperture at 300mm. The sensitivity was set to ISO800. Image stabilization was turned on.
