+1 for La Negatif, also Magnachrom (sadly defunct, but the back issues are all available), Square, Camera Obscura, and also Lomography which despite the hip-factor still has some interesting articles.
The common feature of all the above is that they are online-only magazines, and not film only but they all have a strong film presence in most issues.. I think I've given links to all these in a previous thread (
link). Camera Obscura is a real hidden gem, published in English and German by a Romanian group.
But what are you looking for?
If it's techniques.. then even for digital I haven't found anything original in the monthlies, there's more that's been forgotten than is being discovered fresh, so trawling old magazines or charity shop photography books may be worthwhile. I was looking through my dad's Focal Encyclopedia of Photography from the '60s last weekend and I was suprised by just how relevant it still remains and how much is still to be rediscovered by the FOTM followers.
If it's inspiration.. then I find any magazine that's not specifically a photography magazine is usually a good place to start. Photography magazines are full of images that photographers like, move out of that sphere and you see the images that other people want to see.
