My wife and I are both photographers, she does it for a living and her areas of most work are varied from being our local hospitals' new-born photographer to events and weddings and also a good helping of real estate. We added aerial to her real estate work about three years ago, almost all of which is in the residential field. What we have seen over the last three years is first; as the market increases (especially here in Central Florida), houses are practically selling themselves based on location. In addition as we all know, everyone with a camera on auto is a photographer.
These two things have driven prices down but she still has those clients that will pay for us to do the job right. One piece of advise I would offer anyone thinking of getting into this field is; to expand the scope of your work beyond just aerial imagery. Of all the work my wife does in a year, only about 25 to 35 percent is in real estate and of that percentage, the aerial only makes up maybe 35% in a good year. Realtors that are paying 200 to 300 for all of the ground shots are not always needing the extra Aerial images which adds 150 to the total for 15 photos. So typically we are hired first to shoot the inside and the aerial stuff is the piggy backed on top of that so to speak. Rare is it any of them ask for only aerial shots (again we do mostly residential single family housing).
In addition as it turns out many of the houses where they
do want aerial is not what you think of in Florida - like a super nice house on a beach with a view - those don't need photographs to sell, not from the air anyway. No, what I get assigned are the houses that may be real nice inside but they are
photographically challenged on the outside in some way. Many are obscured from the road or are covered in trees, and then there are those that the 'proximity' to something is the selling point. I get asked a lot to 'make sure to frame the house with the lake in back' and things like that.
So basically if your going to become a photographer from the air - adding ground capability to expand and to 'hook' for the aerial, might be a good idea.
