Take a lot of photos—different angles, different distances, different parts of the plant—and submit the best ones. Digital images are cheap, and it may be difficult or impossible to return for a better image.
Revisit (if possible) the same plant to obtain images of different stages of development. Often fruits and flowers are not available at the same time.
Better to be slightly underexposed vs. overexposed because underexposure is usually easier to salvage in the editing phase.
Framing your subject:
- Photograph diagnostic or distinctive traits of the plant—not just the flowers! Check for diagnostic characters under the Indiana Flora tab on the species page (e.g., https://midwestherbaria.org/portal/taxa/index.php?taxon=72095).
- Follow the Rule of Thirds when possible.
