One of the nicest apps on my new iPhone is Instagram which i am having fun with, hopefully Facebook won't wind it up (i'm assuming they won't considering they spend $1 billion on it!) I do only use the 1977 filter though with its retro colour feel and Polaroid frame. Maybe i should just do all of my photos this way... I suppose the fad might wear off eventually but i can get some nice effects especially when photographing something which hasn't changed a great deal since the actual 1970s, like a motorway flyover for example.
A couple of years ago i took some real retro photographs with a Kodak Instamatic loaded with 110 film. You can see some of them here. It might be interesting to compare real and pseudo retro photos of the same thing! You can see the same bridge as in the above photo (though from a different angle) here. I'll try and take some new photos in Instagram of the same view as a 110 photograph and see how close i can get to the same shot via the various filters!
