I'm going to stick my head on the block here and add another dimension to this. Let's remember that being labelled as a good photographer is a matter of an individual or goup opinion - so Perception plays a part in what may or may not make a good photographer. I've been on 2 websites today - each belonging to a professional photographer. Each of these photographers seems to be able to attract good models to their studio by offering a service as professional photographer. To shore this up, each has posted several positive comments about their work by some of those they have photographed. However, Google the individuals concerned and one finds that each also has profiles elsewhere, each profile containing similar comments about their abilities from the same people that have already commented on the personal websites; so we have a tidy little click going on as well. The reason that I add Perception to the conversation is quite simple: I don't profess to produce the greatest images myself but some of the images that these 2 photgraphers have produced and show on their websites are just absolutely awful, incorrect exposure, unflattering, poor poses (anyone can take photo of a girls arse in flat lighting), a poor understanding of lighting ratios and a very poor grasp of some basic post processing techniques. But these photographers are seen as good photographers and why........Perception, created through the use of personal links and because they advocate themselves to be good because they use the term 'Professional'. I see many images on this and other forums posted by people who call themselves amateurs that are vastly superior to those I saw on the 2 'professional' sites today. But some will never regard those of us amateurs as good photographers because we are just that - amateurs. Please don't get me wrong, the vast majority of professional photographers produce the most fabulous images that I could only hope of achieving - but the 2 of which I speak are clearly not good photographers - and yet people see them as such.
So, whilst I agree with all that has been written above my post, rightly or wrongly I feel that Perception alone can also make a reputation for being a 'good photographer'.
