Depth and Colour August 15, 2009

It’s amazing how the eye compensates when a camera cannot. These pictures, both taken of the same object at 40′ in the fresh waters of Lake Simcoe on the first dive last Wednesday Night, were taken a minute apart. The first was with flash, and the second with natural light.

This gnome sits on the bow of the inboard/outboard boat, and you can see its outline in both pictures, although the remaining background is black with the flash photo, as the exposure time is too short to pick up the ambient light.

Even at much greater depths in the same location, colours are still quite apparent. On the Deep Adventure Dive, I’ve pulled out coloured objects and we’ve noticed that even orange and red are quite discernable at that depth, but every photograph taken even at shallower depths is predominantly green.
