I wandered into the Vancouver Aquarium, not quite sure what to expect. Very near the entrance was an entrancing exhibit of wonderfully beautiful, jellyfish. They were graceful, colourful, and elegant. Getting a good image through the glass is not as difficult as you might think. First of all it is very important to turn off your flash. There were a number of people taking pictures with their phones using a flash and all that they got was a reflection of their flash in the glass. Try and find a bit of glass that is relatively clean and get in nice and close. This will limit the number of reflections that the sensor will pick up. If you have a lens hood on put it right against the glass and you will get almost no reflections. The room was dark so that helped eliminate distractions seen through the tank and I opened up to f.2.8 to throw the jellyfish in the background into a pleasant blur. I love the way that vibrant purple provides a striking counterpoint to the ivory of the jellyfish bodies.
