Random Object Photographs

[PALADIN85020]

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.

Many thanks for the detailed explanation and illustrations. You have a great setup there - way more advanced than I thought!

That's really just an interim rig.

It's a piece of particle board on top of a couple of sheet metal filing cabinets. It's good enough for now, but could be a lot better.

I eventually plan to build a purpose built macro photography table using a 2' x 4' x 3/4" sheet of MDF on top of either black iron or structural pipe. The desk lamps will be replaced by studio light fixtures on Super Clamp and Magic Arm clones. That menorah looking thing behind the subject stage will eventually have a couple of inexpensive manual speedlights triggered wirelessly from the camera.

All of that presupposes a job in the near future. Got a phone interview any minute now...

Those are the kind of pics that speak to me and this one says a lot.

Andy, thanks so much for the detailed information!

Amazing, the things I've learned just hanging out here on this forum.

You're welcome, sir. Once in a blue moon or so I feel like I have something to contribute here; the rest of the time I just listen.

Incidentally, if anyone wants to know just what slag is, and is for, I would recommend just googling it -I'm sure that they explain it much better than I could.

Pair of canvas backs, mid-west circa early 1900's best of my knowledge.

I like these two! I wonder how many duck hunts have been seen by those little eyes over the previous century. They look to be in remarkably good shape. When you say "midwest", is there a particular location? Did you pick these up during your travels or what? Just curious.

Hey Watchdog. I actually picked these up around 1978 at the Flea market in Raleigh. I was living in Kinston at the time.
After I got them home I got I call from the seller that wanted to buy them back for more than I paid. I really don't remember now what I paid for them initially.
I did a book search and found some similar from decoys of the mid west. So that was my assumption. I guess I should search the web now

Speaking of macro shots - I call this one "Just another day at the office." Pentax K-3 (APS-C), Pentax SMC-FA 100mm f/2.8 Macro WR (equivalent to a full frame 150mm on this camera), 1/250 sec., f6.3, ISO 100. Taken on a Spring morning a year ago near our home.

Great info and explanation! Thanks! Every day I learn something is a great day - unless it's learning my taxes are due.

And unlike me, the cat seems perfectly content in an office environment. That's a beautiful cat...so clean looking!

I picked most of this up on photography forums, YouTube videos, and to a lesser extent from a couple of photography books.

What I picked up here was tabletop/product photography, especially how to build a light tent for more diffuse subject lighting.

I've mostly been doing macro lately. I may do some mods on my light tent and photography some pistols, now that I've got sufficiently bright (300w equivalent CFLs) lights.

Nice image.

I've been hoping to get some decent insect shots, but between the cold and the rain, I haven't even seen any gnats here.
