Is portrait the new landscape?
We had 3*4 negatives and we took pictures mainly of holidays and special occasions - it was way to expensive for everyday use. And we put those pictures in a nice photo album. Most of the pictures were of landscapes and situations, so in "landscape mode"
Later we got landscape computer screen because of work orientated applications as spreadsheets and landscape television screens.
Most photo cameras are also easiest to use in landscape mode - so no wonder people take more landscape pictures then portrait ones.
With the Rollei and Hasselbladt square pictures came into fashion in the 1930s.
Mobile phone pictures first were landscape - then suddenly there was a revival of square ( e.g. instagram and hipstamatic)
And now because of Path and FB mobile and the fact we shoot more people then ever (instead of landscapes) people tend to shoot more and more in portrait mode.
Look at our FB time lines - the whole design of it will only enhance portrait mode
The first portrait shot videos are getting published and YouTube will have to adjust its lay-out soon I guess to avoid those black bars on the side...
And think of what will happen to the place of the shutter button of The iPhone?
And what will happen to our landscape oriented iMac screens? Do we get portrait screens - as we already see at airports? - will we see The return of The portrait computer screens as in the Wang word processing days?
And... ultimately... Will we have a portrait TV screen?
