Random Object Photographs

Pond Lilly where we like to go camping in the Sierras.

Tool

I found this old homemade tool in one of my late father's toolboxes.

Someone told me a welder might have made it to use, but I can't remember what it might have been used for. Knocking off excess material? I don't know welding terminology, and dad wasn't a welder, though he may have fooled around with it in his younger days before I was born. I know one of his brothers had a body shop back in the thirties.

There's used to be a narrow gauge railroad from Cloudcroft down the mountain to Alamogordo, NM. It carried logs down to the sawmill. It's long gone now! The only thing left is the Mexican Canyon Trestle.

I like that. Looks like a movie set, doesn't it? For some reason, Charles Bronson comes to mind. Or Eastwood in Two Mules for Sister Sara.

It looks like a home made slag hammer to me. :confused:
 
End of the Road

Doesn't get much more random for me. Out walking around with a camera as I often do, probably wandering on and off property I had no business on...stumbled across some old cars. Didn't get real close...I have an aversion to coming up on critters unexpectedly.

This one's seen better days, of course. Kinda sad to me...probably was once some family's pride and joy, or a young guy's first car. Who knows?

Jim, I sent the pic to my professional nut turnin' brother and he said your dad had the same creative genius that ours did.

He probably needed a chisel less prone to knuckle bustin' and took a punch, ground the end into a chisel and welded a screwdriver handle on it. Judging by how mushroomed the punch point is, that's from hitting it with a hammer.

As they said in the Air Force, that's mighty fine 5 level thinking right there.

A Small Beginning

This seven-week-old Rottweiler puppy is already starting to form the animal-human bond that will guide him for the rest of his life.

He and his new human Best Friend will hopefully share many years of love, fun, and adventures together.

I used to do a good bit of welding, and that is a homemade welding chipping tool, or slag hammer. It isn't for chiseling, but for chipping the slag off the surface of a weld. This is done for several reasons, among them to: a)inspect the weld beneath the slag for defects/voids, which then need to be rewelded; b)to prepare the weld underneath for the application of additional welds in joints which require them; c)to prepare the weld to be painted(slag on the surface will eventually chip off, exposing bare metal); d) to chip welding "spatter" from the surface of the metal surrounding the weld. I'm not certain, but I believe that modern welding methods have made the slag hammer obsolete(I haven't welded in years.).

For more accurate and comprehensive information, we have at least one professional welder here on the forum. Unfortunately I'm not certain of his username, but I think it's "G-Mac" or something close. He makes and sells target stands here. Maybe he'll stop in.

Back to all the wonderful pictures of random objects. Please pardon the interruption.

Andy, thanks so much for the detailed information!

Amazing, the things I've learned just hanging out here on this forum.
 
A leatherworking edger. Stack of 242 images.

Cmort - as one photographer to another, I understand the concept of image stacking to provide sharp focus over a wide range of the subject matter.

However, I have never found it necessary in macro photographs - usually just tightening the aperture sufficiently with a longer exposure time, using a tripod, suffices to get clear focus over a wider range.

Can you share with us your rationale for stacking so many shots?

Thanks,

John

  1. While narrowing the aperture will indeed create a greater depth of field, this only works up to a point. Depending upon the lens, smaller and smaller apertures will result in more and more diffraction and softer and softer images.
  2. At macro distances and magnifications, it may in fact be IMPOSSIBLE to have the entire subject in focus, regardless of how much you stop down. This is especially the case when using enlarger lenses and microscope objectives.
  3. I can't tell you why the specific number of images was chosen, since my software (DSLR Controller) made the choice, not me. I shoot macro with the camera tethered to an ASUS Zen 8.0 Android tablet. I use DSLR Controller to control the camera. It uses it's own algorithm to determine the number of shots. This algorithm can be manually overridden, but I don't have enough experience to do so with consistently acceptable results.
See the attached cellphone images of my rig.
