Not your typical science blog, but an 'open science' research blog. Watch me fumbling my way towards understanding how and why bacteria take up DNA, and getting distracted by other cool questions.
I could almost hear Scott Joplin's music (used in old silent movies, you might know "the entertrainer") playing while watching this :)Which equipment did you use (hardware and software) and how much time did it take you (scripting and filming)?Jeremy
I originally only planned to use the movie in talks, but was just thinking that the online version needs a soundtrack... I'll have to figure out how to add one - Scott Joplin is a good suggestion.I used iStopMotion (the $50 'family' version) and a Logitech webcam, both of which I bought about 10 days ago. My setup was very rough - just a couple of 100 watt desk lamps on a lab bench, with the camera held on a ring stand lying on the shelf above the bench. I spend a week messing around (and doing other things of course) and then did the final version over the weekend.Now I have a better idea of what I'm doing I could do a less-jiggly job. I'd love to eliminate the flickering bands of light and dark, but this is apparently caused by an interaction between the camera's virtual shutter and light-intensity fluctuations due to the 60-cycle period of alternating current.
A couple of other problems could probably be eliminated if I used a better camera. This camera has auto-focus that can't be overridden, which caused it to always focus on the center of the image, leaving the surroundings a bit blurred. I'd prefer to sacrifice the perfect focus at the center in order to get better focus farther out. I think the camera must also automatically control exposure, because no matter how brightly I lit the surface, the final images looked dim. The camera has excellent image quality out of the box, but absolutely no user-adjustable features.
This is pretty awesome! And you can eat the materials after filming – quite environmentally friendly, and yummy. Need to make more animations of various cellular processes!
