Macrophotography

Post by ed »

Came across this thinie on instagran the other day.
https://www.amazon.com/gp/product/B07DR ... UTF8&psc=1
I figured that they ccd is probably good to excellent quality and the rest of it who cares. Here is a picture of a proof mark of an early german pistol

The focus on the thing is iffy. I bought a rail but just had a brainstorm... if I fix the camera and then. rather than focussing it use this
Image

I figure that I can bring the thing into focus without jarring the camera.

Then I can take pictures of small things efficiently.

Then I have to find something else to do. :mrgreen:

Find an old enlarger and use its column. On mine I can even swap the head for a platform with a thread to affix a camera. Looks like this:

Dragged out an old enlarger that I had used as a copy stand. :D

Note that plate. I had the machinist at my grad school make that for me many many many years ago.

I think Ill hold the thing on with cable ties unless anyone has a better idea

Rubber bands, easier to add/remove. Thin piece of cardboard or cork on the metal plate so as to not scratch the camera body.
You have a macro lens, I gather?

Check the OP, the link wasn't working.

I looked the thingies up. One spec they never mention is resolution in megapixels. So presumably you'll get something like screen size.

Which can perfectly suit your needs.

But don't hope for more: at these reproduction ratios (that's already microphotography, not macro) you'll need a high aperture lens (constrained by diffraction). Costly, needless to say.

The setup. Note the rail. $12. Not terribly smooth focus but I'm over it. this sort of setup would have cost thousands back in the day

Gotta square the damn thing. Maybe not, the stuff I care about is going to fit right in the middle of the field.

You could try working horizontally, just use a smooth tabletop. Crumpled alumin(i)um foil would easily hold your "camera" in position, you'd just have to prop up your subject somehow, or glue it temporarily to some holder.

I was going to ask the same thing. Ed has a ruler that measures millimeters and centimeters?? *Snicker*

That is not funny in the slightest. In the middle of critical adjustments I don't need to be triggered.

eta thats 1/100's of an INCH gradations my friends, INCHES!!!

Why not 1/128th? You got the decimal pest? :twisted:

Americans are flexible in their measurement methods. But there are limits beyond which we will not go.

Saved for posterity.

So let me get this straight: up to 1/32 you use the dyadic scale. And after that you switch to decimal. Would that perhaps be (perish the thought) because your gOD-given Murican units become somehow cumbersome at that point? :BigGrin3:

Actually, when dealing with the likes of you I use 1/4. 1/8. 1/16 etc.

When dealing with the manufacturing side of my life it as all 1/1000's.

Like a flotsam of Eurotrash skimming over the waves and altering their prattle from one romance language to another, I can move between traditional imperial measures and decimal equivalents. But if someone uses kgs or mms or some other devil spawn, I will be like the Catalonian being spoken to in Basque!!! :x :x :x It happens at their peril!!!

The set up that I have now will work for the occasional use. Actually, I'd really like something that I could clamp to the desk. Thus:

Thing is that I am probably going to use it a lot now and in 6 months it will be on ebay. <sigh> knowing onesself does have downsides

Remind me again how many screws with metric threads are in those lunar landers that we left up there?

It shows that we embrace diversity. Even unto worshiping stone megaliths and describing them as "cathedrals".
