Benefits

1. The resultant photographs are almost 2 dimensional in appearance. In this type of photograph, buildings have hardly any roof showing.

2. When photographing buildings, the views behind the building can be included in the photograph.

3. The image the camera is seeing can be viewed live at ground level, which allows the exact image to be composed prior to the photograph being taken. Ideal for people who already have a mental picture of the type of shot they want.

4. All camera settings can be controlled from ground level allowing the correct exposure to be obtained. The horizontal and vertical rotation of the camera can also be controlled from ground level.

5. Haze is not an issue like full size aircraft aerial photography is.

6. No CAA restrictions preventing its use.

7. Photography can be undertaken at short notice and for prolonged periods of time.

8. The photographs are precise and rich in detail.

9. Individual properties can be picked out and photographed on their own.

10. Can easily be deployed in a built up area

11. Eco friendly as no emissions are produced from the mast.

12. Can be deployed anywhere on land at very short notice

Disadvantages

1. Can not be used to cover large tracts of land like aerial photography using full size aircraft can.

2. Height of photograph is limited to the height of the mast

3. Some of the smaller masts (50 foot and below) can not operate in medium to strong winds with out the need for guy ropes to stop the mast from swaying in the wind. The larger masts like the 84 foot ones can be used in medium to strong winds without guy ropes.

It is possible to use remote control aircraft with cameras on board to take aerial photographs of subjects on the ground.

The law changed on the 1st January 2010 and now all remote control aircraft used for aerial photography are subject to Civil Aviation Authority Regulations (CAP722) and the operator should have a permit to operate remote control aircraft for commercial aerial photography purposes.

Failure to comply with the new rules is likely to result in prosecution, even the police are not immune.

Advantages

1. They can operate below the CAA height restrictions for full size aircraft (up to 400 feet)

2. Since they fly lower than conventional aircraft the pictures can include views as well as buildings

3. Can be deployed from almost any safe location providing a suitable take off and landing area is available

4. Not normally affected by haze like full size aircraft aerial photography is.

5. On some systems the image the camera is seeing can be viewed live at ground level, which allows the exact image to be composed prior to the photograph being taken. Ideal for clients who have already have a mental picture of the type of shot they want.

6. Eco friendly – especially the electric aircraft

Disadvantages

1. Can not be used in windy conditions.

2. A permit from the CAA is required by the operator to fly remote control aircraft:

  • Over or within 150 meters of congested areas for the purpose taking aerial photographs.
  • Within 50 metres of any person, vessel, vehicle or structure not under the control
    of the aircraft operator.
  • During take-off or landing however, the aircraft must not be flown within 30 metres of any person, unless that person is under the control of the aircraft operator.

3. Area covered is limited to the operator maintaining eye contact with the aircraft (maximum distance 500m), unless a UAV is used.

4. With electric aircraft, the time in the air is limited by the life of the batteries.  So several battery changes may be required during an assignment.

5. Non-eletric model aircraft suffer from vibration caused by the engine – if the plane does not have a suitable camera mount, the photos may be blurry.

or within 150 meters of


Benefits

– A large area (up to a few square miles) can be shown in a single photograph.

– Large areas can be photographed quickly along a route, ideal for showing the terrain, the route of a river or road.

 

 

 

Disadvantages

 

There are many rules and regulations relating to this method of photography, this in turn makes it costly.

  1. Often undertaken by photographers who do it illegally.
  2. The aircraft is normally limited to a minimum height of 500 feet (about 1.8 times the length of a football pitch) or 1000 ft (3.6 times the length of a football pitch) over congested areas.
  3. This type of photography needs planning as a flight plan needs to be filed, so there is normally a lead in time between commissioning the photograph and it taking place.
  4. Haze caused by heat and pollution can result in the final photograph lacking contrast. To prevent haze being an issue, early in the morning, late evening or during the winter months are the best times to photograph from the air as the pollution haze is less prominent.
  5. To get close up photographs of buildings and objects on the ground, the photographer needs to use a telephoto lens. Careful elimination of vibration from the aircraft is required otherwise the photograph will be blurry, this is especially true if large heavy zoom lenses are used.
  6. Alternatively some photographers use very high resolution cameras and then crop the photograph on a computer afterwards. In addition the use of telephoto lens can distort the distance between subjects in a photograph.
  7. When photographing buildings using this type of aerial photography, the building normally shows up as mainly roof.
  8. Unlike some of the types of aerial photography, the views from a property can not be included in the photograph.
  9. Unless their is room in the airplane, the client is dependent upon the photographer interpreting their brief and getting the photographs they require. With some of the other types below, the client can see the exact composition of the photograph before an image is taken. Ideal if a client has a mental picture of what they require.
