What’s Up?
Somewhat surprisingly, I lost 3 pounds on the Palouse trip. Go figure…. I slept eight hours last night until awakened by a vicious cramp in my left calf. It was good to get back into my routine: a swim and an ice bath. This blog post, which took me about 2 hours to prepare, is the 155th in a row. It should be published just after midnight eastern time on Friday, June 12, 2015.

This in-camera Art Vivid (+/- 2 stops Dynamic Range) HDR image was created on the first Palouse IPT with the hand held Canon EF 24-105mm f/4L IS USM lens (at 58mm) and the Canon EOS 5D Mark III. ISO 800. Evaluative metering +1 1/3 stops yielded a base exposure of 1/125 sec. at f/5.6. AWB. Center AF point/One Shot/Shutter Button AF as framed. Click on the image to see a larger version.

Mystery Meat; What Is It?
Subject matter in the Palouse is both varied and interesting. Easy question: what is it?

Hi Artie,
That’s the shaded underside of a bridge. ( look for subjects in the shade.)
Slowest shutter speed. -2 stops from 1/125 is 1/30 th.
ISO 800? Hand holding 24-105 IS at 58 mm gives you a more workable shutter speed for the three HDR exposures.
Nice image made me think.

David
I think that it is made of wood. Might be a water wheel or turbine.
Some kind of larder?
BTW I like graffiti. 🙂 Though not on monuments and really old places.
It’s the inside of a dam or water control system.
I think it is the bottom of an old concrete grain storage bin or mill. definitely looks concrete to me.
I believe the base shutter speed would have been 1/30 sec. That is the reason for ISO 800, as you were hand holding the camera. A lower ISO, like ISO 400, would have taken the base shutter speed to 1/15 sec, which is to slow to hand hold and assure a clear image.
Would the HDR capture, requiring three images, also require either faster shutter sppeeds or tripod? Or does the build in software automatically crop to compensate for movement between shoots?
I came up with 1/30th sec by taking 2 stps from the base of 1/125. 1 stop = 1/60, 2 stops = 1/30.
Looks to me like the baffle system in a concrete storm drain or water overflow ?
I’m going to say your slowest shutter was 1/4 sec.
Looks like the undersides of an old railroad bridge.
Did you have to worry about graffiti out there?
I love photographing covered bridges and nothing irked me more than to see something so
wonderful ruined by vandalism.

Thanks Doug, I will make a blog post out of your question at some point. If I forget, please remind me. artie
ps: this is not a covered bridge…..
Oh, I know its not a covered bridge. Just using it as an example.
Doug
p.s.: Artie, don’t forget that blog…ok, I reminded you 🙂
Nice try on the reminder Doug 🙂 a
