Note: I have an audience of one in mind when I write these kinds of posts - me. While some might find them useful anyway, it's me writing to myself, about things I struggle with.
I rarely get a good image from a trip that didn't require a big effort from me, so big that it made me feel miserable (unfortunately, it doesn't work the other way around: feeling miserable doesn't guarantee that I'll get a good image).
My best images were made on days where I had to push myself beyond not only my comfort zone, but also what I thought were my limits.
I love the feeling of exhaustion after a whole day of shooting, looking at those negatives or RAW files, and finding out you captured what you saw.
It's ok to be miserable. It feels good.
