A pinhole image of the Ferris Wheel during the Rose Festival in

Portland, Oregon. This was about a 20 minute exposure. Enjoy and

feel free to comment.

Terrific image! Amazing how sharp the lamp has come out through this pinhole camera without a lens...excellent color and sharpness. How did you calculate the exposure?

I guessed Animesh. ;-) I figured it needed at least 10 minutes to 30 minutes so I split the difference. The difference between a 10 minute and a 30 minute exposure is only about a stop and a half so I was pretty safe. Plus I had been out a few nights before this shooting similar shots at about the same time with 100 speed film and those came out ok but too thin, so I came back with 400 and kept the times close.

Great shot. The light trail from the passing car is one of the prettiest I've seen in a long-exposure photo.
