Often surprised, Velvia always surprises me with how colourful it is. I can take a shot of a sunset, and think 'this will look great on Velvia', and when I get it back (even though my composition etc. might be poor) I'm always surprised by how vivid the colour is.
Long exposures often surprise me too, sometimes due to movement in the scene (planned or unplanned) or sometimes due to reciprocity characteristics of the film I'm using.
I want to try new things and be surprised.
I just got two 4x5 sheet of Fomapan out of the tank, exposed in my pinhole camera a few days ago.
Not only do they appear reasonably well exposed, but the development seems OK too.
Every time I do this, it seems like witchcraft has taken place.
I never get the image that I saw. That's why I love photography.
I think it's an illusion that you get exactly what you want, or that you know exactly what was captured and how, with digital.
You can see on the LCD screen, sure, but with a little experience you can be as confident about what you captured on film.
Either way, you don't know that everything turned out exactly right until you get the image enlarged, either on a computer screen or on photographic paper.
The results sometimes are not what I expected but it's rare. I would agree with her that instant confirmation with digital is an advantage. I think it's the biggest advantage digital can offer. Other things not really.
