I'm continuing my exploration of the prairie using high speed video recording on the iPhone. These small flies were busy one morning last week and tolerated the close up attachment that requires a distance of about an inch for optimum focus. Recorded at 240 fps which means one second of action translates into 8 seconds of video. Now if I could afford a more sophisticated camera that records in high speed. Most cameras limit the shooting time to a few seconds because of the intense onboard computer commitment to process and store that volume of information. The high end cameras have a pre-record feature so you can save the action after it has happened. This is a great feature since it can take several seconds for a camera to transfer the information to a memory card.
