I think one of the most difficult aspects of photography is the editing process (choosing your best images). Garry Winogrand famously said, “Sometimes photographers mistake emotion for what makes a great street photograph.”
Winogrand famously shot like a madman (shooting several rolls a day for his lifetime), but had the discipline to not even process his photos for a year after he shot them. Why did he do this? In order to forget the memory of having taken those shots– so he could be more critical and objective when it came to choosing his best images.
It is always easier to judge and critique other people’s photographs. Therefore one of the benefits of forgetting some of the shots you took is that you can look at your own photos not like that of your own– but that of a stranger.
