I read on 365 somebody ( sorry I don’t remember the name) asking people if they shoot square framing or landscape ....as I’m also active on Instagram I’ve to crop my landscape shots in square ones but I wouldn’t say which one is the best : the square one with only the swan or the landscape that include the other side of the lake and far the French mountains ... so I would say it depends... but I will continue to shoot rectangle to eventually crop it square ...
