• The only light for this scene, one exposure only illuminates the wall and floor nearby. Which is why this took 6 exposures: 30,20,15,8,4,2 seconds.
  • This is the first time I really photoshopped an image. I removed the electrical cord to the light and the trail drawn in red tape.

HDR Lower Cave Carlsbad Caverns

Newer Older

Although you may take the Lower Cave tour in Carlsbad Caverns, New Mexico, you may not recognize this cave opening at first glance. But I promise you, you will pass through it on the lower cave tour if you take it. This cave is looking back into the pearl beds from the main lower cave room. This image maximizes the light through a technique known as High Dynamic Range photography. Multiple exposures at various times from 2 seconds to 30 seconds combined to show a long cavern illuminated by dim and bright lights. I did a few more exposures than was recommended by Peter Jones because I wanted to bring out the details in the back of the cave.

Believe it or not, here are the min and max exposures that go into this image: www.flickr.com/photos/samurai_cat/201455634/ www.flickr.com/photos/samurai_cat/201457934/

If you would like to see close to what I have done with your eye, you can try though it will not be the same image (the eye processes things differently than a camera, and more so still than a light compression math technique). Still, if you find the cave from the the trail and your tour can stop for a moment. Look at the cave and close your eyes, count to about 20-30 seconds, then open them. The light will be brighter than this, but you will see some of the color captured here that you don't normally see from the dull gray light you see in the corner.

Enjoy, and happy caving!

    Thank you! This was probably one of the most complex images I have ever attempted, I will have to do so again soon to prove I really know how to do it all from start to finish, including white balance.

    this is the first ever shot of the inside of a cave that's lit so evenly. congrats on a well executed shot! brilliant!
    btw. who's peter jones?

    Peter Jones was our workshop instructor: www.extremescience.com/PJones.htm

    A great guy and friendly teacher, I at least learned a lot (I think) and tried all kinds of new methods. This particular image was the most complex one I have ever attempted since it requires so many shots to even out the light.

    Makes me think of the J. R. R. Tolkien’s novel ‘The Hobbit’. How I imagine the cave of Smaug the Dragon to be.
    Very rich, great shot.

    Nice HDR cave photo.

    this is what I would call taking the 'crafting' of an image into the digital realm. Truly gorgeous result, as well as magical use of the light-collecting aspect of the digital camera. not an analogue image, but not trying nor claiming to be. Uniquely digitally rendered, with raw material from the natural world.

    a view into a world I would never otherwise see. thanks!

    Cool! I like caves they are so cool, but I don't get to be in them often.

    This is an amazing HDR capture! I love to go into such caves, and I know how hard it is to take pictures in there (well, if your tour guide is chasing you through the cave without giving some minutes for photographers).

    Great photo.
    I'm am doing a trip to Carlsbad in Feb. I used to go there quite frequently about 20 years ago. I'm looking forward to it this time because its the first time I'm doing it digitally.
    I'm looking forward to using various combinations of f stop and aperature, using a remote flash for unusual effects and such.
    Its a great place to go in the winter because there aern't too many people and the weather is always great underground.
