I've also enjoyed photography since my teen years, including experience in the darkroom, but wasn't very good at developing my own stills. Like Thirdsystem, nature-themed imagery is my preference. They make for good album covers.
I also enjoy time-lapse photography, and have been fascinated by it since watching Baraka back in the 90s. Luckily with DSLRs, it's an easy task. My first attempt was using a DV camera back in 2000 for a short film. I shot it in real-time, captured it into the computer, and sped it up 2000% or so. Worked very well.
The benefit of doing it this way is complete control over how quickly things moved in post. Doing it in the DSLR (as actual stills) means you need to know how often to take a photo to get the speed you're looking for. However, a benefit of using a still camera allows for very long shutter speeds in darker scenes.
