In 1924, 29 years before Tenzing Norgay and Edmund Hillary summited Mount Everest, George Mallory and Andrew Irvine made an attempt to climb the mountain. They were last seen high on Everest making their final push for the summit. Nobody knows for sure if they made it, because they were never seen alive again. But they carried a camera with them, and it is ...

Photo films and papers are made from salts of silver that naturally only darken when exposed to violet or blue light. In the early days of photography, this was all that was available. Therefore these films and papers are able to be handled under any light source that does not radiate blue light. By the way, the violet and blue frequencies of light are the ...

Going from negative film to a printed image is a two-step process. First, the negative is developed — the latent image on the film brought out and then fixed in place. Now you have a piece of translucent film with a negative image on it. Second, to go to a the final print on paper, you then essentially repeat the process, shining light through the negative ...

This is just a passive dial (that does not communicating anything to the camera mechanism), meant as a memorizing aid for the film type and speed inserted. The degree values are DIN speed numbers. C seems to be a shorthand for generic "Color" film. CT, CN17 and K appear to be shorthands for various Agfa film stocks that were contemporary for that camera: ...

The sale price of film is going up because of “economy of scale”. In other words, the more you make of any particular article, the lower the cost to make that article. Digital imaging has overtaken film imaging and this movement continues at a rapid pace. Thus as film sales drop, the cost to manufacture goes up. It is as simple as that!

Before roll film there was sheet film. With sheet film a photographer could select particular films with particular emulsions individually for every shot they took. Applicable characteristics of a film's emulsion would include sensitivity/film speed, fineness of grain, color response/balancing, contrast, as well as the overall 'look' that different films ...

In the darkroom, place a piece of the material you will be developing, flat, face up, on the work space. Place a handful of coins on this material. Using a timer, remove a coin every 5 minutes. 12 coins will cover 1 hour. At the end of the time span, develop the film or photo paper. A perfect darkroom will leave no evidence. An unsafe darkroom, reveals ...

Film negatives are only light-sensitive while in the camera, until they are removed and processed. The processing includes a step to "fix" the image so that the negatives will not be further exposed by light. So once processed, film negatives (and slides) can be handled in daylight.

First an explanation; this answer extensively borrows from and combines points from a number of the existing answers to this question. To those from whom I have borrowed, thanks. A short answer to this question is "very little" but that hardly does justice to the intent of the question. So I'll make a long answer and divide it into sections. Spectral ...

Film makers avoid a transparent film because: Bright exposing light will penetrate and then hit the pressure plate. The pressure plate has a flat black coat. Nevertheless, highlights are bright and will reflect, re-exposing the film from the rear. This causes a halo like effect surrounding highlights called a halation. To avoid, modern films have an opaque ...

Make negatives specifically for the course: Ask yourself what you want to actually teach in your class, and come up with negatives to function as aids to those lessons. If all the students are going to learn is how to mix chemistry, expose photo paper, and what order/timing to dunk the sheets in the tanks, then why on earth is anyone Paying for that when ...

There are two and a half parts to this answer. First part: if you are in LEO (low Earth orbit) (The only EVAs outside LEO were part of the Apollo programme) then you're inside the Van Allen belt and the radiation environment is therefore significantly nicer. No humans have been higher than LEO since Apollo. Secondly, if you're outside the Van Allen belt, ...

The white balance should be indicated on the box and the datasheet for the film. There aren't too many choices though. Most films are daylight balanced for shooting in direct sunlight (approx. 5000K). If you were shooting in open shade (approx. 6000K), you were expected to use a slight warming filter to get rid of the blue cast. If you shot daylight-...

Along with weighing down the tripod, using a cable to release the shutter will help reduce camera movement. Also, if you want to guarantee no mirror shake happens during the exposure, hold a black object in front of the lens while triggering the shot, then pull it away for the duration of your exposure.

Well, it seems obvious that the film did not advance between shots. Whether that's because of user error (film not installed right so it didn't catch on the advancing mechanism) or a hardware issue with the advance mechanism not working properly can't really be determined without more information and/or inspection of the camera... Try taking a couple shots ...

I understand that, on a digital camera, "exposure compensation" actually alters signal amplification, similar but not identical to changing the sensitivity. In general, this is not how the term is used. Instead, "exposure compensation" means: tell the camera's exposure program in automatic exposure modes to target an exposure brighter or darker than the ...

It is highly unlikely for a format to be lost in a way you describe. All the standard processes were thoroughly documented, and good documentation will keep for longer than unprocessed film. But home processing of some materials - such as mentioned Kodachrome (K-14 process) - is extremely impractical. Because of the iconic status of the process it has been ...

Wikipedia page: Lomography Lomography was a fad from some time ago which involved using cheap, old Russian film cameras, primarily a camera called the LOMO LC-A, to create pictures with a poor technical quality. The term is a trademark of Lomographische AG, an Austrian company who now manufacture that and a range of other cheap plastic cameras for sale in ...

No. Aliasing is result of sampling, taking discrete samples or readings of a signal, at a low enough frequency that the frequencies in the input signal are confused for other frequencies, such that they cannot be distinguished from each other. If film grain were aligned with regularity, their spatial frequency would create opportunities for aliasing, just ...

I'd guess you're under-exposing a long way & the lab is having to work them really hard* to get anything like an image out of them; hence the amount of noise in them & no real blacks anywhere - but I'll leave it to someone more versed in film photography to post a fuller answer. *From comments - I had mistakenly used 'push' as a term for which I ...

Contrary to some comments here, a 135 film cartridge is very open to water intrusion. The film slot and both spindle holes are designed only to keep out light. The cartridge filled with water in just a few seconds after it was submerged. If you still have a a professional photo lab, preferably one with a darkroom and someone who knows how to use it, I would ...

Kodak started making "pocket" cameras in 1895, and each new design used a different film format — different sizes, aspect ratios, cartridge types, and orientations. By 1908, they decided to simplify the confusion with a numbering scheme, calling that first format "101" and continuing the numbering up from there. So, that's the scheme — the numbers correspond ...

Mirror slap is an issue in "medium" long exposures - from 1/30 or so til about a second or two. Tripod shake is issue in "long" long exposures - from about a second upwards. For shooting stars you can safely forget about the mirror slap. It will last about a second of the four hours exposure. Nothing of importance will be captured in such a short time. ...

This camera was mainly intended for use by amateur photographers who only occasionally used the camera. Film was loaded, some pictures taken, the camera was generally set-aside to be picked up latter for an occasion. This second or perhaps third session might be next week or next month or even next year. When the roll was finished, then it was sent out to ...

In theory you can get more out of a negative than a print. However, in practice you are more likely to have access to a flat bed scanner that can give a wonderful scan from the print. A good film scanner is much more expensive and slower. Considerations are similar for larger format film. But the costs go up even more, since the consumer-level film ...

That's an old point and shoot camera that took 110-format film. For that reason, they're usually called 110 cameras. You can even see that term, "110 CAMERA," on the label on the camera in your photo.


21

What were long, flat point and shoot film cameras called? You don't want to know what I called the cheap 110 Instamatic I was forced to use when I was young and couldn't afford anything better! The reason they were called 110 cameras is because they used the 110 film format introduced by Eastman Kodak in 1972. They were immensely popular in the 1970s and ...

Ilford Delta is a pretty common film. I am certain you will be able to find a reputable lab to develop it somewhere around (you do not mention where exactly in Germany are you spending your year). On the other hand, you should not have a problem developing it yourself in a years time. To maximize your chances you should keep it cold - in a fridge, or even ...

Doing double exposures with the k1000 requires that you cock the shutter using the lever while simultaneously holding down the release on the camera bottom. This allows the shutter to cock while not advancing the film. Check to make sure that this release button isn’t sticking in.
