Our rules of composition
If you want to upload photos to PlanePhotos.Net you need to respect a few basic rules of composition.
The photographed object can be shifted outside the center of the photo, but the rest of the picture should not give impression of emptiness , ie there are placed some other objects (eg Sun, Moon, other aircraft, mountains,...), so that photography as an ensemble has balanced effect.
Cut off main parts of aircraft is considered as wrong composition (unless it is clearly not a detail photo or a photo of part of the aircraft).
So you cut photos, that all main parts (rudder, elevator, wings, landing gear) were complete on the picture. As a rule - if cut, rather bigger piece than less. There is one exception - the helicopter main rotor blades can be cut off.
Composition in the pictures below is unacceptable
... but the composition shown below is OK.
We do not require central composition, but we consider it best for most photos. For common photos you can use 2:3 or 3:4 aspect ratio (or 1:1 if it is appropriate due to composition), widescreen aspect ratio can be used only for 'airport overview' or 'wing view' photos.
