Camera Stability and Long Lenses

January 29, 2014 G Dan Mitchell 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 →

Autumn Flurries, Morning

An early autumn weather front drops morning snow flurries along the rugged Sierra Nevada crest near Mount Morrison

This is another photograph from the final morning of our September photographic trip to the eastern Sierra Nevada. We were surprised to find it snowing lightly when we work up in Mammoth that morning, since there had been no mention of such weather in the previous day’s forecast. We decided to stick with our plan of making a big loop out to the east of Mammoth Lakes and then north by a back route to Mono Lake and highway 395 for our return trip. So we headed down the road out of Mammoth Lakes in the pre-dawn near-darkness and then started out across Long Valley.

Out in the valley as dawn approached, it became clear that the atmosphere was doing some very interesting things along the eastern edge of the Sierra. At first we saw a very strong weather cell over Mammoth Lakes that appeared to be dropping quite a bit of rain or snow, even though where we were it was virtually clear overhead. So we stopped and set up to make some photographs of these conditions. We continued shooting after the first red dawn light and watched as the snow squall worked its way south along the Sierra crest. In this photograph there is light snow falling along the ridge near Mount Morrison, but since the clouds did not extend to the east, the early morning light is hitting the upper slopes of this line of peaks.

Autumn Snow Squall, Sierra Crest

October 22, 2013 G Dan Mitchell 1 Comment

An early autumn dawn snow squall along the crest of the Sierra Nevada above Long Valley

On the last morning of our October aspen chasing (mostly) trip to the eastern Sierra we were surprised to wake up to snow that had not been in the weather forecast. It seemed that a local squall was centered more or less over Mammoth Lakes, where we were staying. We had a vague plan to do a loop far out to the east of town and then head north toward Mono Lake by back-roads, so we quickly loaded up the vehicle and headed out of town, first going south on highway 395 and then turning off to the east.

As we drove down the hill from Mammoth Lakes there was enough light for us to see a substantial squall to the east and a lot of cloudiness elsewhere along the eastern edge of the Sierra. We were headed right toward the squall, and we stopped as we got in line with it… as it more or less vaporized and blew away. But now we were able to look back toward Mammoth and the Sierra in the pre-dawn light, so we set up here and decided to wait and see what the sunrise light might reveal. The little storm above Mammoth continued to drop a mixture of rain and snow, and it gradually spread south along the crest as the first dawn light arrived.

Rocks, Surf, and Dusk Horizon

August 7, 2013 G Dan Mitchell Leave a comment

A curving rock shelf extends into the “blue hour” Pacific Ocean surf and toward the fog-darkened horizon as night approaches.

A short, evening visit to the California coast above Santa Cruz began with photography in golden hour light in areas where the fog bank hung just offshore with moist air over the coast creating a gentle, misty atmosphere and soft light. We photographed a few subjects in this light – and looked at others that we did not stop to shoot – and continued north as the sun dropped toward the horizon, where the fog waited to envelop it. We stopped at a beach where large groups of pelicans were resting and then resuming their flight along the coast, and noted that there was still a bit of light in the sky and, oddly, below the bottom of the fog bank along the horizon. As this light died, we turned briefly north, and I soon saw this rocky bench extending into the ocean waves.

Following the evening golden hour there is a time that some call the blue hour – when the warmer colors of sunset drain from the sky and we are left with soft, blue light. It might have seemed odd to anyone watching me photograph this rocky feature, but instead of hurrying to shoot it before the light faded, I took my time – I wanted the light to fade, both for the mysterious blue coloration and because this would make it easier for me to use extended exposure times to allow the water to soften and blur a bit. When I began shooting it was only dark enough to get exposures of perhaps a second or two – at least without adding a neutral density filter – but as I waited, making an occasional photograph in the interim, the light began to move toward a near-night state, and I was able to get exposures of 15 seconds or longer… and that blue light that I was looking for.
