See For Yourself

Do you want to explore unknown Patagonia and discover the marble caves of Lago G. Carrera and other treasures for yourself? Linde Waidhofer and Lito Tejada-Flores offer an annual spring photographic workshop that you can join. For details of the 2010 program, see their website at www.WesternEye.com.

Linde and Lito also dedicate their time and talents to the environmental campaign “Patagonia sin Represas” (Patagonia without Dams). To view Linde’s images of the landscape threatened by the project and to learn more about the campaign to protect Patagonia’s pristine wilderness areas, visit www.savebiogems.org/patagonia/ and www.conservacionpatagonica.org.

High-Definition Video

Canon EF 24-105mm ƒ/4L IS USM
The Canon EOS 5D Mark II’s HD video adds a whole new dimension to our photographic repertoire. For this project, both of us are carrying cameras with this capability, so we can capture the beauty and mystery of the caves and the movement of the water, while documenting the photographic activities as well. In video mode, the EOS 5D Mark IIs we’re using have automatic exposure control. When moving from a bright sunlit entrance into the darker depths of the caves, the camera adjusts the exposure automatically, using a combination of expanded ISO and aperture settings to maintain the best possible video capture under varying conditions. This effect is fascinating because you can watch it happen on the LCD on the back of the camera while you record; as you move from light to dark, the camera resolves an under- or overexposed area before your eyes. The most difficult part of video capture in these conditions is to maintain the stable platform necessary for smooth results. Using an image-stabilized lens like the Canon EF 24-105mm helps.

Because the EOS 5D Mark II’s video is full high-definition, it looks great as part of large-screen presentations. We like to think that the slight, inevitable movement resulting from photographing on the lake helps viewers to experience the mystery, beauty and constantly changing light and water of the caves as if they were right beside us in Pedro’s little boat!
