Present day image of Chaos Crags and Lassen Peak in Reflection Lake with historic image of 1915 Lassen Peak eruption from same location
Repeat photo pairs, like this 1914 photo of Lassen Peak in eruption and a repeat photo from present day, create a “then and now” view of Lassen Volcanic National Park.
 

Kick-off September 24, 2016 | National Public Lands Day
Help capture the 100th anniversary of both Lassen Volcanic National Park and the National Park Service by taking photos of your visit. To participate in the Lassen Centennial PhotoBlitz:

  1. Pick up copies of one or more selected historic photographs of the park at the Loomis Museum or Kohm Yah-mah-nee Visitor Center or print copies from this online gallery at home.
  2. Use the historic photos to create a present-day repeat image. Learn more about how to do this below.
  3. Share your historic photo re-creations* with the LassenNPS on Facebook, Twitter, Instagram, or Flickr with #LassenPhotoBlitz or email lavo_information@nps.gov, subject: Centennial PhotoBlitz.

*By sharing your photos, you agree to allow the National Park Service the right to reproduce, prepare derivative works of, distribute or display and use these materials in whole or in part, for government and non-government purposes, in any manner or media (whether now existing or created in the future), in perpetuity, and in all languages throughout the world.

How to Create a Repeat Photograph

  1. Study the historical photo for season*, weather, and time of day. Try to capture your repeat photo at the same time of day and in similar weather conditions, the angle and intensity of the sun dramatically changes the appearance of features in a landscape. *A repeat photo may be taken in a different season than the original photo and can actually help highlight interesting seasonal variances.
  2. Identify prominent features such as mountains, ridgelines, shorelines, distinctive rocks or trees, or roads to help approximate the photo point.
  3. Use the prominent features along with any other information about the photo to determine a starting point within the vicinity of the original photo point. Be sure to take the historic photo to repeat with you.
  4. Using the prominent features, move around and try to match the angle seen in the historical photo. The dominant feature and area in front and around it should look the same as in the historical photo.
  5. When you have matched the angle of the most dominant feature, move towards or away from it, matching more features. Remember that the original photographer may have been very tall, or liked to squat down to take photos. Your position can change the angle quite a bit, so don't be afraid to move around. Use your zoom or wide angle to frame and reframe your repeat photograph.
  6. Fine tune your repeat photograph for exactness by matching as many features as possible. Take note to match the horizon line, the edges of the image, and the size of the features. Consider using a tripod if possible.
  7. Take your repeat photograph. If possible, use your camera's screen to check your repeat photograph against the historical photo to make sure it matches as closely as possible.
  8. If possible, note the GPS coordinates of the photo point for future repeat photographs.
  9. Share your repeat photo* and its GPS coordinates with LassenNPS on Facebook, Twitter, Instagram, or Flickr with #LassenPhotoBlitz or email lavo_information@nps.gov, subject: Centennial PhotoBlitz.
