I captured this photo of a sea turtle while at the New England Aquarium. It was a bit of a challenge because flash photography and tripods aren't allowed. In order to shoot the photo and get enough light, I had to use a an ISO of 1600, an f-stop of 3.5 (the lowest number my lens would allow), and a shutter speed of 1/125 sec.(the lowest speed I dare go with a subject in motion). I used a Nikon D3200 camera with a Tamron 18-270mm lens at 18mm. I tried to angle the shot to take advantage of the light inside the tank, avoiding too much reflection from the glass. In post production, I adjusted the exposure & color, cloned-out some unwanted elements and used noise reduction.
