The photos you take during the City Nature Challenge are there to provide evidence of the organism you saw, and to help confirm the identification of that organism. Therefore, taking good photos is key to participating in the CNC!
Focus on one species in each photo: While a meadow full of wildflowers is beautiful, it’s not the best photo for an observation, as there are probably many species represented in that one shot! As much as possible, try to have the one species you’re interested in as the focus of your photo, by getting close and centering your organism in the frame.
Use the option to have multiple photos in one observation: On iNaturalist, you can have more than one photograph for each observation you make, allowing you to photograph different parts or angles of an organism. For example, one photograph of an entire tree, taken from far away, won’t be very useful in identifying that species of tree, but that “full shot” photo, combined with other photos that show close ups of the leaves, the bark, and any flowers or fruits, will allow that tree to be identified.
Discard blurry photographs: Be sure to use the option to retake photos when making observations! If the organism moved or there is low light, causing the photograph to be blurry, retake the picture but wait for the organism to be still or turn on your flash. On iNaturalist, the app will show you the photo you took and ask you if you want to retry or if you’re OK with the photo.
Get close: For small organisms in particular, like ants or aphids, getting a nice close-up shot is important for identification.
