Wonders of Lisbon: The Oceanarium (2)

This is the second of a three-part series of shots taken in the Lisbon Ocenarium (you can see the first part here).

The kit: Canon 1100D, Sigma 30mm f/1.4 lens.

Regardless of all my comments about the main light sources being artificial and originating inside the fish tanks, you can’t keep the sun out all the time

Oceanarium Lisbon 4What’s the logic in that? First complain about not having enough light and then darken your photos by 2/3 of an f-stop? Well, frankly the idea came out of something I’ve been noticing for some time now: when you have light sources ahead of you (lights, windows, signs, inside an aquarium), and you’re metering for the whole frame, the lights get overexposed. I quickly realised this was worse inside the Oceanarium. Probably something to do with the way light reflect and refracts on the water.

Check back for part 3, where I bring you the cast of a famous film: Finding Nemo!
