I'd still love to see what the light looks like when it hits the film/sensor. I mean, it has to produce something. Whether it's a recognizable image or not is irrelevant!

I would imagine that at some point the DOF is so thin that it's nearly nonexistent.

Shutter close, mirror down when you fire the shot, then both re open and close for the actual exposure. So you have now doubled the total amount of noise made. At least this is how it is on Nikons.

Canon has a 'silent shoot' option that primes the mirror so it only slaps down and returns more slowly/quietly. I've never used it, but I think that's the general idea behind it.

FYI mirror boxes fold up outta the way. On Nikons silent mode just waits for you to let go of the release to drop the mirror and recock the shutter.

It's actually a bit more than that. Essentially it combines an electronic first curtain with a mechanical second curtain. quote:Many Canon DSLRs with the “live-view” feature have an interesting feature. They can eliminate the need for a mechanical first shutter curtain by using “a unique high-speed scanning and electronic reset system that accurately mimics the... high-speed mechanical shutter operation. It synchronizes with the mechanical 2nd-curtain shutter to obtain a slit exposure.” In addition, the way live-view has been incorporated in these camera bodies the exposure can be initiated while in “live-view” without any mirror motion. As a result, an exposure can begin with absolutely no mechanical movement at all, and thus no vibration. The exposure is concluded by the closing of the mechanical second shutter curtain. After the exposure there will be some mechanical movement in the camera but this obviously can not effect the exposure (with the possible exception of a continuous “burst” of successive pictures). It provides a significant decrease in shutter shake.

It was the slowest puzzle I have ever attempted, it was easily 250 pieces that all looked exactly the same and another 200 that were blue/white. None of the tricks that work on photograph puzzles were of use.

A5H posted:Huh is that post colour or did they have colour film then? Kodachrome was released in 35mm in August 1936. Professional sizes (120 and up) were introduced in September 1938. It's also possible that high-profile photographers (like Hitler's personal photographer might have been) got pre-production film for testing and marketing purposes, although that is nothing but speculation on my part. There was quite a bit shot through the WPA, and much of it is available through the Library of Congress. Paul MaudDib fucked around with this message at 01:26 on Feb 27, 2012 |

It's pretty amazing how looking at color photos from pre-1060 make everything look like a still from a movie set. It just doesn't look "right" unless it's black and white.

How can a lens be considered to have a focal length if it's incapable of focusing an image? A big plate of glass would be f/0.0000001 if we just look at the amount of light coming through. \/\/\/ Good point. I'm still confused as to how a lens can be considered to have a focal distance (and therefore an aperture expressable as f/number) if it doesn't form an image at that distance.

ExecuDork posted:A big plate of glass would be f/0.0000001 if we just look at the amount of light coming through. Other way around, it would be infinite. Focal length is determined by the distance from lens to the image when you have a collimated light source; since the light through a plane wouldn't change direction the image would be an infinite distance away, thus the focal length is infinite. As the Aperture (or size of the plate) is finite, so it would be expressed as f/infinity.

I remember reading something about a photographer that staged some photos of a Palestinian (Israeli? Iraqi?) officer amid some ruins after an earthquake (bombing?) that ended up on the cover of Newsweek. I think that 'officer' ended up being an actor, or just some guy with an official-looking uniform, posing heroically on rubble. I also remember reading that the photo of a half-burned teddy bear in the rubble of a burned house is the go-to cliché for local news photographers.

It's not film and the technology wasn't lost. It's merely a three-color separation on glass plates, which are combined and projected together. The same idea also underlaid Techicolor (with film obviously).

QPZIL posted:A comment on one of those Nazi pictures mentioned that it's supposedly an early Agfa color negative film. Take that for what you will. It'd make more sense than Kodak at least. Yeah it's Afgacolor Neu. The Prokudin-Gorskii survey was shot on magic lantern glass plates though, which is a bit different. I looked it up, it's actually not on 3 plates like I thought. quote:Prokudin-Gorskii created his negatives by using a camera that exposed one oblong glass plate three times in rapid succession through three different color filters: blue, green, and red. For formal presentations, he printed positive glass slides of these negatives and projected them through a triple lens magic lantern. Prokudin-Gorskii would project the slide through the three lenses, and, with the use of color filters, superimpose the three exposures to form a full color image on a screen. (For more illustrations of Prokudin-Gorskii's methods, see the "Making Color Images" section of the exhibit, The Empire That Was Russia.)

It's pretty hilarious, this ridiculous interpolation they're doing to generate a 41MP image. I get the selling point, but it's all more than a bit silly. That being said, the sample images they're providing are really quite good, for a cameraphone:     No doubt they've likely been touched up, but still.
