Repeat Photography – Documenting a Changing World
This family friendly, full-day field lab introduces you to documenting climate change in the world around us. We will focus on the rapidly changing environment of the Icelandic glaciers, learning how they are affected by rising temperatures and other shifts in weather patterns, and how we can best use our cameras and smart phones to document those changes. We will compare them to observations and images made by other visitors in weeks, months, and years past, correlated them to modern and historic maps, and learn how we can make our own observations available for future reference to other visitors and scientists alike.
Citizen science empowers all of us to gain a better understanding of the world we live in, and modern technology allows us to contribute important observations on a far broader scale than ever before.
No special equipment required; all you need to bring is normal outdoor clothing and your smartphone or digital camera. We will be approaching local glaciers as the subject of our documentation effort, but walk primarily over rock and gravel (and possibly some muddy terrain).
A successful repeat photography project has three stages, each of which we will discuss in detail:
- Location planning. Any new repeat photography project needs to anticipating future changes and figure out how to choose the best view point for documenting them. For ongoing projects, the focus shifts more towards identifying the viewpoint from existing images.
- Performing the repeat shot. Probably the most difficult part is how to set yourself up for the best possible replication of an existing image, even if you are using a different camera or lens from the original shot, but there are a number of techniques and tricks you can use.
- Analysis. Once a sufficient number of images were collected, we will want to compare them. We will touch on methods for overlaying and comparing repeat images, even if there are minor differences in the viewpoints or camera/lens used.
We will also touch on crowd sourcing and existing apps that can support organisers and contributors.
