We are on our way to New Mexico to interview Sandra Ingerman and Joan Halifax for Inner Worlds. While in the area I plan to capture some timelapses to be used as verity during the interviews.
I could use my Sony EX-1 for capture, as it has a built-in timelapse feature, but I find that using RAW still images I can achieve a much wider dynamic range and use many of the features that the Develop Module in Adobe Lightroom has to offer. Though you can use any camera that is capable of shooting time intervals, I have found that using my Canon Mark III with an intervalometer gives a great deal of control. In most cases I can adjust the highlight and shadow detail of the RAW image in Lightroom to capture the dynamic range I need without shooting and processing HDR’s.
To put together the timelapses I use LR Timelapse 3. LR Timelapse 3 allows you to keyframe as many images as you want, giving you the option to change the exposure, cropping, color balance, etc. throughout the entire timelapse sequence.
Here is the final timelapse shot in Dolpo, Nepal:
One of the big problems of using a DSLR for timelapse is flicker. Since, most cameras are not exactly accurate at faster shutter speeds and when the automatic lenses stop down, you want to avoid shooting stopped down (i.e. f11, f16, f22) or at fast shutter speeds when doing timelapse. I don’t like to shoot any higher than f5.6 and use a slow shutter speed of 1/30 or 1/60. This will require that you use a neutral density filters for some daylight shooting.
