If you are using a cell phone, make sure you turn your flash on. This will help decrease shadows and increase edge definition.
Try to only have one subject in a picture. This will aid in good identifications.
Ideally, photograph multiple views of the same subject.
When photographing fungi, make sure you also get a photo of the underneath part of the cap.
With bees, make sure you photograph a view of the abdomen patterning. This is very important with bumble bees.
When photographing trees, photos of the bark, leaves and branching pattern are helpful.
Blurry pictures will absolutely make identification almost impossible.
Remember, the closer you get to a subject, the less that will be in focus (limited depth of field).
With butterflies, both sides of the wings are important in determining identification.
Always take more than one photo of a subject, especially insects.
Look for unique characteristics of any subject. Anything unique will help with identification.
Rulers are the best items to use to show scales, coin size isn’t, not everyone uses US currency.
No houseplants or non-native plants. Only photograph plants and trees in the wild please.
For iNaturalist.org no photos of people, dogs, cats, or other pets!
