Dormant and live trees form patterns against a cliff face, Great Basin National Park

On my first visit to Nevada’s Great Basin National Park near the end of September, my initial impression was that the “big features” of the park that probably draw the most visitors are two: The Lehman Caves near the entrance and visitor center and the high, alpine area close to Wheeler Peak, the highest point in the park and the second tallest in the state of Nevada. I did not visit the caves, but I did spend a fair amount of time high up near the peaks, photographing and hiking to the alpine lakes and the bristlecone pine groves. (My one regret is that I started out a bit too late on the bristlecone pine visit, and I didn’t have enough time to cover the additional two miles up to and back from the Wheeler Glacier.)

Eventually, as typically happens, I had made my acquaintance with the iconic subjects in the park, and I started to feel the familiar impulse to look around a bit for things that might not be so obvious or immediately impressive. The first foray was up a gravel road past some less developed campgrounds, where I came across at section of low cliff running alongside a gravel road and stream bed. The autumn colors were just beginning to arrive here, so I got out and wandered a bit, looking for juxtapositions of rock and tree. This little vignette attracted my attention, and I was fascinated by the pairing of a living tree full of leaves (albeit just about to turn colors and drop) and the nearby bare, white branches holding only dead leaves, with both set off from the rock behind them.

Camera Stability and Long Lenses

5 Comments

I responded to a question somewhere else and thought that it might be useful to share the response here, too. A photographer asked some questions about using long focal length telephoto lenses for landscape photography and how to deal with the issue of camera/lens stability, bringing up related questions about things like live view modes, mirror lockup, image-stabilization, and so forth. Here is what I wrote in response…

If you are shooting landscapes from the tripod…

  • Do use live view – it is the mode that introduces the least amount of shutter vibration.
  • Either mode 1 or 2 will perform essentially equally well when it comes to shutter vibration. (In both cases, there really isn’t any shutter motion vibration before the exposure since it is initiated electronically.
  • If you use a remote release (and you do, right?!) then there is no reason to use any delay setting on the camera to avoid vibration. (Many cameras have settings for 2 second or 10 second delays – mostly there so you can run and get in the photo, too!)
  • Mirror lockup is irrelevant in live view. The mirror is up by default in live view.  To be even more explicit, live view and MLU are mutually exclusive modes – they cannot be used at the same time.
  • After touching the camera, moving the tripod, etc., wait a few seconds for vibrations to dissipate before making your exposure. I  think that 2-3 seconds is sufficient, though some folks will claim that even longer might help.
  • Speaking of this, I would tend to avoid using either auto-focus (AF) mode when making landscape photographs with such a long lens. Either can introduce some amount of vibration to the system, but especially the mode that momentarily flips the mirror down, auto-focuses in the usual manner, then flips the mirror up to make the shot in live view. I prefer to manually focus at 10x magnification. If you must autofocus, do so before switching to live view mode, and then turn AF off before making the exposure.
  • Realize that the large area of these big lenses, combined with their very long focal lengths and great magnification, make the system far more susceptible to vibration from air movement. Even relatively weak breezes can create enough vibration to create a bit of blur and soften the image. Continue reading Camera Stability and Long Lenses →

Yet Another Reason to Like Live View – Shooting in the Wind

5 Comments

I have posted in the past about some of the advantages of having a live view feature on your camera, especially for the types of photography that I do using my Canon 5DII. This past week I discovered another use, and an unexpected one at that – shooting in conditions of gusty winds.

I most often work from the tripod, and I usually use a pretty large and stable tripod in the context of shooting a full frame DSLR camera. But in some very windy conditions putting the camera on a tripod is not sufficient to stop camera motion and the consequent blur. This is especially a problem when you are shooting in low light or otherwise need to use very long exposure times, and it becomes worse when using long lenses which will catch more wind and magnify vibrations. There are a bunch of tricks that you can try in order to keep the camera steady, but in really strong winds the camera is just going to move, especially if you have a very large lens attached.

One way I try to deal with this is to time my exposures for moments when the wind may momentarily decrease. This can require a lot of patience – sometimes I’ve had to wait several minutes for a very brief halt to the gale, during which I try to make my exposure. But even in this case, you have to make sure that the camera vibration stops completely if you are using a long lens. Ultimately, you have to simply trust that the camera really has stabilized since there is no way to tell directly. Last week, as I was using live view to focus a 400mm lens on a distant subject and again noting that 400mm plus 10x software zoom in live view makes the camera very sensitive to vibration. In the past I have noted this mainly in the context of how darn hard it is to manually focus a big lens this way! But this time it occurred to me that I could use this in my favor.

With the 10x live view magnification enabled, the display is very sensitive to camera motion from the wind. I realized that by leaving the camera in the 10x magnification setup after composing the shot that I could simply watch this display, with its magnification of motion, and wait until the image stabilized during lulls in the wind to take my shots. If the display isn’t bouncing at 10x, motion blur is not going to be an issue. Problem solved. More or less.
