While I’m not in favour of any ‘faked’ event situations in this forum, almost all of the aircraft photos on here have been altered in some way, either by being processed on the camera or, more likely, in an image processing program.
The most important thing is to show the aircraft (to those of us who are not able to attend the events that are covered) in an interesting and aesthetically appealing manner. To everyone who posts their photos here I say a hearty, “Thank you all”, for taking the trouble to do so.
