Hi Steve
First off, welcome to the forum. I hope that you will find it to be a useful resource.
Photography, by its nature, is diverse and I have not seen satellite imagery used in this way before. Thanks for bringing it to our attention. It is certainly interesting and has an aesthetic attraction.
As for whether such pictures would be eligible for club competitions, my view is that Chris is incorrect when he says it is a grey area. As currently written, the rules do not prohibit the use of someone else's work. However that is just semantics and the introduction to the rules states:
"The main objectives of internal competitions are to provide a means by which members can obtain feedback from experienced photographic judges, to provide an element of competition and to provide some fun, all of which is aimed at improving standards."
We are a camera club and one of our aims is to help members enhance their photography. While they are not explicit in that regard, the spirit of the rules is that images submitted into competition are photographs which are entirely the work of the entrant. That is the reason that Chris said it is a grey area. I am afraid that I do not really agree when you say there is "skill in researching locations and arranging a successful composition". I suppose that there is some editing expertise involved, but nothing which could be described as being photographic.
I suggest that you ask yourself a number of questions:
- Does submitting these satellite derived images help me to advance my own photography?
- Would I be happy to compete against someone else who was using work obtained from another source?
- Is this something I really want to do, when the primary objectives are improvement and enjoyment from friendly competition?
My suggestion is that rather being submitted into club competition, use of such images would be better suited to a presentation at a members' evening.
If you still wish to go ahead, you should note that the section on image manipulation states:
"Manipulation is accepted in the Print & DPI categories provided that ALL elements are created SOLELY from the member’s own work."
The main purpose of that section is to ensure that composite images are created entirely by the author. Since there is no definition of manipulation, technically just about anything which can be done in a photo editing application would count. The sole exception I can think of would be cropping.
Long answer, but your question raises some valid points. I hope that you have found the response informative and that it helps you come to a decision.
