They say film photography forces you to think more because every shot costs you money. Digital is "free".
I disagree. In fact, I believe digital photography can be very, very expensive.
Time is the most valuable thing we have: every day, we are all given 24 hours. The way we spend those hours is mostly up to us.
At first, film might look like more time consuming: we need to develop our negatives and scan them. Personally, I'm more concerned about this than the monetary cost per frame. The time I will need to spend to bring those pictures into my computer is what holds me back when shooting film.
On the other hand, shooting digital doesn't have that "cost". There are no steps in between pressing the shutter and having the images in our computer.
This is the digital trap.
It's a trap because we often end with many more images when shooting digital. Even if we discard most of them, we need to invest some of our precious time scanning through all the photographs.
Ideally, we'd shoot digital with a film mind: no monetary cost per frame, no time needed to develop and scan them and no time spent scanning through a lot of images.
