Death Valley Days

March 3, 2015 JimK 5 Comments

I went to Death Valley for the weekend. I took an IR-modified Sony a7, and an unmodified a7II, plus three lenses: the Coastal Optical 60mm f/4, the Nikon 28mm f/1.4 D, and the Zony 35mm f/2.8 FE.  I ended up using the Nikon 28 on the IR camera almost all the time.

I placed a spare battery and a charger next to my case as I was packing, but I must have forgotten to put them in, because they were nowhere to be found when I got to Furnace Creek, and when I got home, there they were on the desk.

The Sony alpha 7 cameras have a fearsome reputation of chewing their way through batteries, so I was worried.

I needn’t have been.

I made more than 1500 exposures on the IR-modified a7 the first two days, and checked the camera’s battery on the morning of the third: 52%. I swapped the nearly-full battery from the a7II in, then made about 300 exposures on the last day. When I got home, the camera said the battery was 82% charged.

I am surprised and pleased. I was shooting panos, had auto review turned off, and only turned the camera on when I thought I might want to make an exposure. I’m sure all that contributed to my results. The first battery was a  Wasabi 1.3 amp-hour unit, and the second a Sony 1.02 amp-hour one.

Here is a first cut at some of the pictures.

    Nice set, Jim, I especially like #1 and #5. I hear you about the 28mm being most used out of the three. As a hiking landscaper I find that 20mm cuts down on the number of captures needed even further 🙂

    Great shot Jim, and thanks to share your experience with the battery on the a7/a7II!

    Jim,

    I’m curious about the background/history/origin of panoramas which are not rectangular in shape. From a source point of view I can see that it would be useful to have this since various different rectangular crops can be made from the original. Is there a reason that you prefer to display this format instead of showing a more standard rectangular shape? When you print the panoramas do you crop to a rectangular shape or do you preserve the original shape.

        Thanks, now I understand where you are coming from. I’ve been looking through your old blog posts. There are lots of interesting topics that you cover in great depth which I appreciate being an engineer myself.
