Using the 7d mark II with Canon 70-200mm F4 capturing the kids in the pool, well actually diving into the pool. Most of these shot at ISO1000 F8 at around 70mm, and heavily cropped in post from the original. Despite the heavy cropping, the images are great. Shutter speed did vary depending on the light, usually around 1/1250 to 1/2000 of a second. Everything shot jpeg, processed in PSE 10 with Perfectly Clear.
