A Tale Of Two Images

The False Slot - ©Daniel Gauss/Shot On Site

"False Slot"? This is nowhere as big as it looks. A kind of optical illusion, if you will. It's actually a massive boulder immediately north of the Pony Hills Petroglyph site in Luna County, New Mexico. Sometime in the distant geologic past it had broken into two parts. In reality, what looks like a one hundred foot long slot is closer to 20 or 30 feet, and about 12 to 15 feet high, and let's just say way too narrow for a slightly plus-sized septuagenarion like myselft to traverse. So,  kind of an entertaining illusion, right?

I wasn't sure the image above was going to come together. I had taken the two images below, with slightly different exposures, trying to get something that was balanced. I wasn't crazy about either, but I decided I would see what I could do with it back home at the computer. 

 
By now, you know that my editor of choice is Luminar Neo, and I was just itching to get this into the HDR Merge extension. There was a problem, though. These two images were just hand held. I did have my tripod with me, but pure laziness on my part kept me from setting it up.  As a result, when I pulled the two images into the HDR Merge extension, I had to opportunity to try out a function of the tool I hadn't needed in previous images:  Auto alignment.  Turns out it works pretty damn well. As you can see from the third image below which is a composite of the two images at 50% opacity, they weren't lined up very closely at all. Compare it to the finished image at the top of the page, and it put them together nearly perfectly. I say "nearly" because while the viewer will not see any fine details that didn't quite mesh, I can. I can always see the faults.  It's my curse. 😐

  

Have a look at the top of the right sidebar, and you will see an ad for the Mothers Day Sale, which has just a few more hours to run... till 7:00 AM EDT, May 16 to be precise. If you look and the ad's no longer there, you missed out again. 50% off. Or 60% off if you also use the code, PHOTODAN at check out. Later, all.

Autumn is nice in New Mexico, but...

 ...monsoon brings out the very best in photographic opportunities!

Here's what Wikipedia has to say about our monsoon:

"The North American monsoon is a complex weather process that brings moisture from the Gulf of California (and to lesser extent the eastern Pacific and Gulf of Mexico) over northwestern Mexico and southwestern US resulting in summer thunderstorms, especially at higher elevations. Monsoon rains account for 35% to 45% of total rainfall in the desert Southwest"

Thunderstorms mean heavy (but scattered) rain, and more importantly, lightning! Nothing is more satisfying than capturing a great lightning image.  For a long time, before the digital era, nothing was more frustrating than trying to capture a great lighting image! One had to stand in the rain with a cable release in hand, and the shutter dial set on "B"... push the plunger for a set amount of time and hope that a lighting strike occurred when the shutter was open. Lather, rinse, repeat.

With the advent of digital imaging, many cameras of the advanced amateur and pro levels came with an intervalometer setting. One could specify a certain number of exposures, at a specified interval, and the camera would then do the heavy lifting, while the photographer enjoyed a cold beverage in front of the TV. When the storm subsided, the memory card was loaded in the computer, and the hunt for any frames with a lightning strike would begin.  That's how I captured the image below way back in 2011, also from the front porch. To this day, I think this is still the best storm to ever pass over our heads heading West.

This method had it's obvious drawbacks, of course. The number of shutter actuations vs the number of images of lightning was excessive, considering the lifespan of shutters back then.

The solution was having a device that would only fire the camera when there was actually a lightning bolt! These devices did exist then, but for many of us the price was prohibitive- $500 and up.

Then, in 2016, I began to see ads for a device that didn't cost an arm and a leg and promised I'd be able to capture lightning, and a whole lot more! That device was the Pluto Trigger ! It was only $119 then, and it's still $119 today. I bought one, of course, and have been very pleased with it's capabilities, not only for lightning capture, but so many other functions (but more on that in another post). The image at the top of this story was made possible, in part, with the Pluto Trigger. (Follow the link to learn more).
