Subject: Corn earworm (Helicoverpa zea) time-lapse

Methods: Developmental stages of the corn earworm with mixed time-lapse and real time video microscopy. The images were collected with a Nikon Eclipse SMZ1500 stereo zoom microscope and a Nikon Ri1 color camera. The images were processed with NIS-Elements BR image acquisition software and ImageJ processing software. The movie was done in collaboration with Cell Biology student Devahuti Ramnarine. Music: Where the Hills Are - A Tiny Window.

Subject: Hatching brine shrimp (Artemia salina) time-lapse

Methods: This is a short time-lapse video of hatching brine shrimp (Artemia salina), also known as sea monkeys. It represents about 24 hours in one minute. The movie was done in collaboration with Cell Biology students Anjali Seenauth and Tom Thomas. Music (Cello and Rice) by Brendan Finucane.

Subject: Stinkhorn, probably Calthus columnatus or Pseudocolus fusiformis

Methods: The sequence of 3000 images was collected at 4 min intervals with a Canon PowerShot A510 digital camera. The images were complied into a QuickTime movie using ImageJ, a public domain Java image processing program. The movie is presented at roughly 35 fps.

Subject: Mung bean (Vigna radiata) seedling taking up rhodamine

Methods: A three-hour image sequence (1 min intervals) was collected with a Nikon Eclipse SMZ1500 stereo zoom microscope and a Nikon Ri1 color camera. The images were processed with NIS-Elements BR image acquisition software and ImageJ processing software.

Subject: Developing fruit fly (Drosophila melanogaster) sequence

Methods: Images were collected with a Nikon Eclipse SMZ1500 stereo zoom microscope and a Nikon Ri1 color camera. The images were processed with NIS-Elemens BR image acquisition software and ImageJ processing software. The movie was done in collaboration with Developmental Biology student Qilong Song.

Subject: Germinating alfalfa (Medicago sativa)

Methods: A three-day image sequence (2 min intervals) was collected with a Nikon Eclipse SMZ1500 stereo zoom microscope and a Nikon Ri1 color camera. The images were collected with NIS-Elements BR image acquisition software and processed with ImageJ processing software.

Subject: Variegated sea urchin (Lytechinus variegatus) sequence

Methods: Images were collected with a Canon PowerShot A510 digital camera. The images were complied into a QuickTime movie using ImageJ, a public domain Java image processing program.

Subject: Flowering Lobivia tiegeliana

Methods: The sequence of 284 images were collected at 10 min intervals over a 48 hour period with a Canon PowerShot A510 digital camera. The images were complied into a QuickTime movie using ImageJ, a public domain Java image processing program. The movie is presented at roughly 14 fps.

Subject: Stinkhorn - species unknown

Methods: The sequence of 319 images were collected at 10 or 20 min intervals with a Canon PowerShot A510 digital camera. The images were complied into a QuickTime movie using ImageJ, a public domain Java image processing program. The movie is presented at roughly 7 fps. The smell was funky, and the compilation is tragic.
