Our photographers aim for about 25 photos per every 1,000 sqft. If the home is more complicated or has a lot of details that need capturing, the photographer may take a bit more (and vice versa if the home is less complex) but this is a good guideline.
Other services have hard limits. For example, Twilight shoots include up to 20 photos, Pick-Up Shoots include up to 10 photos. Aerial Stills include up to 15 photos.
