There are many reasons why you wouldn't want to shoot with film. It is time consuming, can be messy and you have to be patient. You have to be patient because the results are anything but immediate. Sometimes you wait weeks from shooting the photograph, through finishing the roll, developing, scanning, printing, etc. etc. etc.
So why do it?
For me it is very simple. I love the aesthetic quality of film. Some may argue that it is not as sharp as digital - but that is the point in my opinion. As someone once said (HCB) "Sharpness is a bourgeois concept".
I don't need immediacy. Looking through a set of negatives or scans is a little like opening a Christmas present. There is the excitement of what you are going to discover, the hope that it will live up to your expectation and (sometimes) the joy of getting exactly what you wanted.
When a 64 year old camera and some fast grainy film produces an image like this I feel like all my Christmases have come at once.
