This comes down to you area of photographic interest, the easiest way is to go down to your local newsagent or bookshop and browse, that way you are not locked into a subscription for something you may find later doesn't suit your interests.
Thanks Craig Sherriff; went to local book store: narrowed down to 1) PhotoPlus The Canon Magazine; 2) Digital Camera World; 3) Outdoor Landscape & Nature Photography
There is another source of magazines and that is online, go on to magnetdl and this will allow you to down load, plus have a look on YouTube heaps of stuff there.
