Do you have a favorite photomicrograph you’d like others to see? It could be the winner!

Buchsbaum Photomicrography Contest Rules

  1. There are separate categories for color and black-and-white photomicrographs.
  2. Photomicrographs taken using transmission electron microscopy, scanning electron microscopy, and any kind of light microscopy, including confocal scanning laser microscopy, are eligible.
  3. The contest is open to all SICB meeting participants; up to 3 entries each. AMS membership is welcomed but not required.
  4. Submissions must be unmounted prints, with maximum dimensions of 8 X 10 inches, unlabeled and unsigned. A single line of information identifying the subject (e.g., “Mouthparts of a mite”) and stating the microscopical technique (e.g., “SEM”) should be below the photograph.
  5. Entries will be accepted on the morning of the first full day of the meetings at the AMS booth in the exhibit hall, where they will be displayed as a group. The deadline for submitting entries is before the exhibits close for lunch that day.
  6. Voting begins on the afternoon of the first full meeting day and ends at the end of the first coffee break on the morning of the third full meeting day. All meeting participants who visit the AMS exhibit are allowed one ballot for each contest category.
  7. The winning entries in the color and black-and-white categories and entries awarded “Honorable Mention” will be determined by a tally of the ballots and will be announced at the at the AMS luncheon on the third full day of the meeting and at the AMS booth thereafter. The prizes will be awarded at the AMS Luncheon. Contest winners are invited to the luncheon as the guests of AMS.
  8. All entries must be reclaimed on the afternoon of the third meeting day, before the exhibit hall closes.
  9. The author retains all rights to the entry. The author grants permission to AMS to publish the image in Invertebrate Biology and on the AMS web site. If the image has been published previously, the author should obtain appropriate permission from the holder of the copyright.
