One of my Christmas gifts was an intervalometer, or time-lapse/timer remote, for my camera. (I'm still confused on whether it's timelapse, time-lapse or just time lapse.) You can set it up to take pictures every x seconds/minutes/hours. You can have it be continuous or a set number, and there are some other options I haven't really explored. Then you can take all those photos and put them into a little time-lapse video! It's something I was interested in trying, and I've been having fun experimenting.
My first few attempts didn't work so well (a scene that barely changes doesn't tend to make a very exciting video for some reason), but yesterday I set my camera out on my deck all day and there happened to be a lot of cloud and light variation over the lake. It was actually a very nice day for January. So now I'm sharing this video with friends because what else am I going to do with it? It's just a minute long, but it depicts several hours of pictures. Oh and I didn't do anything with the photos to color correct or change the exposure--I was just working on the mechanics of the video more than the photography aspect.
I have some other ideas and might show you more resulting videos sometime.
PS Sorry if you have already heard of this through other social media. :)
PPS Christmas/SF pictures to come!
