This old station is on the way home from my parents place at the lake. My son was asleep so I stopped and got some shots. I am now planning on finding some classic cars to bring down there to shoot. Neat little place

I like the first shot a lot. What did you do to get the blurring a lot the top and upper left corner? #2 needs rotated a bit or it will fall over.

10mm lens and a 3 shot HDR

Great find, Greg! I'd really like to find an old station like that for some shots.

Great subject! And your idea of having some classic cars involved should make it even better.

That make sense. Those parts moved.

One thing I'll throw out here that is not directly relevant to this series, but which I should probably put in the Coffee House or something is this:

The motion issue is a problem in many instances when image stacking is going to be used. However, bearing in mind that a RAW image has a bit depth of 12, if one captures an image where the dynamic range cannot be represented as-is on an 8-bit display device (such as a computer monitor or a paper print), nonetheless, it is possible to still use HDR, and without the motion issue.

If you take a single RAW image that has a histogram that is well centered, you can produce from that a series of exposures in developing that image and then process those through the HDR software without the issue of motion. I have done this, and it works. It is how I processed my entry for this month's challenge.

If you consider how eight bits fits into twelve, with a perfectly centered exposure, you can make at least three and perhaps four EV images from the same RAW file with 1 EV spacing. Then these can be processed through whatever HDR process you like.

When I thought of this and tried it, I felt like it was "my idea", but it will likely turn out to be a technique that is common knowledge that I was just unaware of.
