I know you plan to pair your bellows and lens combo with a film camera, but if you have a DSLR with the same format as your "new" film camera, why not mount it on the bellows and see in live-view what effect stopping down at various apertures yields? If nothing else, I believe you'll discover that, ...

Linear, for sure. In another life, I used a Leitz Dialux Pol microscope for optical crystallography. Its polarizers weren't film, but rather carefully calibrated and oriented calcite prisms (nicols). Crossed nicols result in total extinction.

I'm not familiar with your camera or with Sigma lenses, so this post may be a bit or even completely off the wall. My Nikon D810 and Nikkor lenses allow me to set focus and then switch from auto focus to manual focus on both the camera body and lens. Lenses retain the focus I select manually or that...

Frame it, hang it on the dining room wall, and enjoy your guests' reactions when you tell them what it is.

Interesting that, in your image, the left antenna is apparently rooted lower on the ant's face than the one on the right. I've noted the same on an ant-face of an entirely different species that I photographed some time ago. Thus, I assume it's not a one-off peculiarity but a normal characteristic. ...

I doubt that anyone can look at a photo and determine what brand or variety of camera support, if any, was used to create it. In terms of results, such things just don't matter that much. Here I have to disagree. Even if it does not show in endresult (the percentage bad results because of using inf...

According to the specs that came with my PB-6 bellows, a 50mm f/1.8 Nikkor lens will yield 4x magnification at 208mm of extension. Reversed, the same lens yields only 3.9X at the same extension. Reversed, however, provides about 8mm more working distance. Neither setup results in vignetting and, to ...

Thanks for looking and for your comments, Ray. In the hand, the coin is actually a dull, dark brown, but I fiddled with the color and brightness during post processing with the hope that I could bring out more of its original detail and the Shawes Patent modification. I should have noted that. Why t...

In his youth, my maternal grandfather, born in 1883, roamed the hills around the junction of the Big Sandy and Ohio Rivers near Huntington, WV in search of fossils, mineral specimens, projectile points and other lithic tools, military buttons, spent bullets, and whatever else caught his eye. His col...

Remembering the dwarf-planet Pluto in the dwarf-month of February. Priceless!

My temporary "studio," for lack of a better term, is located in my crowded garage. I set up my equipment on a homebuilt, mobile workbench with a maple butcherblock top. Excluding the maple top, the bench is relatively light, utilizing torsion-box construction for the deck, drawer dividers and ends. ...

I think this topic is headed down the drain.

I've been a Nikon user since 1965 and have used nothing else except a couple of Sony and Canon digital point-and-shoot cameras for less serious applications. Oh, and a sweet little Rollei 35S I carried on hikes back in my Kodachrome days. I have no experience with other brands of serious DSLRs or mi...

A little puddle of ferro-fluid in a Petri dish suspended above a pretty strong neodymium magnet. Focus stack of 20 images at 1.25mm increments using a manual focus rail. Illumination provided by two Godox LED mini-panels, each dialed-in to a different color. RAW conversion and aligned and merged usi...
