Photographic projects can last weeks, months, even years. This could be on how a subject changes over time or how the seasons have an effect on the subject. Alternatively it could be on a given technique, i.e. infra red or extremely long exposure, which shows the subject in a different light.
These are projects that I have started , but not yet completed. Photographs may be added and later removed as I work on the subject or the direction of the project changes.
