Photography/Photo collections

There are many collections of subjects for a Sim to photograph. These are shown in the skill panel after the first subject has been captured from that set. When trying to capture a photo for a collection, make sure that the game gives it the caption for the shot.

Oddly though, all subjects are shown as difficulty 1 except the Doubly Dead which has 5 difficulty.

Plants and Flowers
24 subjects. Pictures of various plants. The common plants can be found around your base Neighborhood, but some require travel to all three vacation destinations. Having the Gardening skill will help.

The plant has to have sprouted to be recognized as a subject for the picture.

If you are having trouble photographing garden plants, check to see if you have a sprinkler covering them.

Architecture and Buildings
11 subjects. There is a problem reported by some player that some rabbitholes are not registered as the subjects of this photo collection, to get the subject you must move your sims to another town and capture the picture there.

There is a problem reported by some player that some Rabbit holes are not registered as the subjects of this photo collection, for example Brunton's Boxcar Diner is the diner for Twinbrook but when you try to capture the picture, the diner subject doesn't appear. So if the player want to get a diner subject, they must move their sim to Sunset Valley or Bridgeport and capture the picture there.
