Take the number of photos required to positively identify the species. Especially of a species where others are very similar and clarity is needed.
I agree with @tiwane. While iNaturalist is great at creating distribution maps and recording location and time, it does little for counts. A flock of birds could be ten individuals. Uploading the same photo ten times to cover each individual will do wonders for your number of observations, it will do nothing for science. So, besides wasting your time and data, if you have a photo with more than one individual of the same species, in my opinion, upload it once only.
My take on this topic is on this site, this date and time, is species Aa and so recorded. I may move to another close by location (different aspect etc) and take a new set of photos which form a new observation.
Researchers will then use your location data to visit the area and do a more accurate species count.
Consider this question " Should I try to be frugal with iNaturalist’s bandwidth?"
