Photography

Note: Over the years the focus of my website has shifted more towards climbing trip reports, so I stopped actively updating my photography section around 2015 or so. But, there are still several great photos here, so enjoy!

I was first introduced to timelapse photography when I joined a team doing a documentary on North Cascades glaciers. Timelapse is a great way to add a dynamic aspect to photography.

What are timelapses? Timelapses are created by taking a series of still photos and stringing them together to show a fast-forwarded version of how the captured scene changes with time. In this way, hours of real-time can be compressed into mere seconds of film. The fast-forward speed is dependent on the interval between photos and the frame rate at which they are played.

What you will need: (1) A camera. Can't take photos without that. (2) A tripod. So that every photo captures the same frame so the video flows smoothly. (3) An intervalometer remote that connects to the camera to take a sequence of photos on a set interval. Otherwise you have to just stand there pressing the shutter button manually for hundreds of shots. (4) Computer software to merge the photos into a standard video file (usually at a frame rate of 15-30 frames/sec); there are several simple programs available for free download (I use MPEG Streamclip or Time Lapse Assembler).

The math. The engineer in me likes the mathematical side of timelapse. But don't worry, the math is simple. Say you want a 10 second video; using a frame rate of 24 frames/sec, this video would be comprised of 240 still photos. The following table gives examples of how long you need to run the timelapse and rough guidelines for the interval between photos, depending on the lighting situation. Note that these are only examples, as a timelapse can be made up of any combination of interval, frame rate, and number of photos, it's up to you!

 For 10 second video comprised of 240 still shots at 24 frames/sec.... Example subject Interval between photos Real time Timelapse (i.e. fast-forward) speed Clouds 5-15 sec 20-60 min 120-360 x real time Light 10-30 sec 40-120 min 240-720 x People 1-10 sec 4-40 min 24-240 x Tides 2-4 min 8-16 hours 2880-5760 x

I'm still just playing around with various techniques and learning as I go, but this page shows shows some of my favorite timelapses I've taken.

Length of video: 23.6 sec Real time: 1 hour Number of frames: 354 Interval between photos: 10 sec Frame speed of video: 15 frames/sec Timelapse speed: 150x real time If each one of these customers spent \$2-5, that's a lot of money spent on coffee in one hour! Things to watch for: my sister on her hands and knees, the pink Nalgene, me on crutches, my shoe, ball of tinfoil, seat occupation, flow of customers.... Busy day at the parking lot at Artist Point, Mt. Baker Ski Area. Length of video: 17.5 sec Real time: 43 min Number of frames: 262 Interval between photos: 10 sec Frame speed of video: 15 frames/sec Timelapse speed: 150x real time You could use this timelapse to approximate the number of people that come to Artist Point on a sunny autumn day: (# cars entering)*(2-3 people per car)*(10 hours per day) = .... Cloud movement, weather moving in. Length of video: 60 sec Real time: 7.5 hours Number of frames: 904 Interval between photos: 30 sec Frame speed of video: 15 frames/sec Timelapse speed: 450x real time It began to rain about 1 hour after I stopped this sequence of photos. Watching this timelapse makes me wish I could change the focus of my PhD studies to clouds/atmospheric physics rather than earthquake engineering.... A day of work: Filling an empty woodshed.
