Sadly it was not always a pleasure.
There is a list of official Royal Welsh Show photographers listed on the RWAS website and the company I work for is clearly listed. However, throughout the show we were seeing photographs listed for sale by people who had not purchased media rights, some were even accredited press photographers (though they appear to have no proper press credentials at all).
The company I work for - 1st Class Images - are the only team big enough to cover a show of this size. They also have huge overheads to cover the show: trade stand fees, accommodation, food, drink, insurance, fuel, etc. etc. It is therefore insulting that people who have not gone through the proper channels to be allowed to sell Royal Welsh Show photos are doing so.
By purchasing these "pirate" images, you are risking a situation where there are no official images available to exhibitors at the show. Why would anyone send a team of twelve to cover all the elements of the show (and pay handsomely for the privilege) if others are abusing their credentials as press photographers in order to make a quick buck for themselves?
Some British Eventing competitions now do not have an official photographer. The problem then is that the images available from amateurs are hard to find and generally low quality and unflattering.
