Petri dish & plaque detection

Are you having trouble with petri dish or plaque detection in OnePetri? Here are some tips and tricks to help you get more consistent results:

  • Wherever possible, make sure that your petri dishes are placed against a dark surface with a solid (and not patterned) background and not up against the ceiling/light/window
  • Try to avoid glare or significant light reflections on the petri dishes when taking images for analysis
  • When working with small plaques, try to maximize the petri dish’s relative area in the image by moving your device as close to the dish as possible before taking a photo
