sometimes happy accidents lead to a new and different way of thinking and working where it is no longer an accident because you are able to repeat it at will
and it becomes the "convention" you start using. that is how tools, and techniques are improved and invented.
Most of the work I've been doing for close to the last 10 years are the results of "happy accidents", and being open to where they led. It started with being given a half-frame camera, at a time I was only shooting 4x5. The camera (Olympus Pen-EE) was sitting on my desk, and I had no intention of using it. One day I found an old box of 4x5 Plus-X in the back of a closet. Long out of date, I tossed it on the desk, with no plans to use it. Fortunately, both the camera and film were in my sight at the same time. I started to wonder what I could do to combine the two. I decided to expose/develop the sheets, so I could scrape off part of the emulsion and laminate the smaller negatives onto it. I envisioned a "faux" platinum look. It worked out pretty well, and I began to do it with larger than half-frame negatives (my first Gallery uploads were from this time).
These early attempts led to the second "happy accident". One of the issues I had with chiseling part of the emulsion off was that the base would scratch easily. I ended up tossing a lot of the sheets away. One day, I found a ruined sheet, but took a closer look at it. It occurred to me that it was kind of interesting on its own. I printed it, and painted it. I then saw the possibilities in making photographs without a camera or lens (cliché verre). I started making them, experimenting with different ways to scratch the negative. Examining the results of those cliché verres, it became apparent that I could create designed pieces, with a little forethought. This realization led to the Cityscape series.
Right now, one of my projects has been to incorporate actual negatives into the Cityscapes. It's been frustrating, and I haven't come up with any I'm completely happy with, but I'll get there eventually. If not, I've no doubt that the attempts will take me somewhere new, which is just as good.
Creativity is all about letting your mind wander, without a preconceived notion of where it must go.
