I've just checked my pile: I have most of them from Issue 4, Winter 1999 to Issue 60, 2008.
I was really taken with it when I first stumbled upon it in the newsagents here, but by the time I bought my last one, I had decided that it was just a machine pumping out a stream of rubbish along with the rare nugget: mining became too expensive to be worth the reward. And I put the blame squarely on the Special Issues that were, in my eyes, total rip offs.
A shame, but that was my experience.
Yet, if your memory takes you back to the 50s, you may remember the Popular Photography Annuals which also featured a Colour Annual. I found them both wonderful sources of interesting photographs and there I met the work of so many people that I later came to recognize as stars. I have not heard of the Annuals since; wonder if they still happen. Could be that part of the problem mags face is that people are so much more aware of, and bombarded by images in these current times; nothing much amazes anymore. Sad.
