History[ edit ] Figure from patent US A , issued by Kodak, describing a photographic color process using color-coupling substances, such as the ones used in a chromogenic print. Developing color by using oxidized developers was first suggested by German chemist Benno Homolka who, in , successfully developed insoluble indigo -blue and red dyes on a latent image by oxidizing indoxyl and thio-indoxyl respectively. This turned the dye couplers into micelles which can easily be scattered in the gelatin while loosely tethering to it. They used ionic insoluble carbon chains which were shorter than Agfa’s for their dye couplers, which were suspended within droplets of water in the gelatin layers. It became the cheaper and simpler to develop counterpart to the alternatives at the time,  and could be used in the simplest of cameras. Although the paper’s name was changed to “Kodak Ektacolor Paper” in , the terminology “Type-C Print” persisted, and has become a popular term for chromogenic prints made from negatives still in use today,  with the name “Type-R Print” becoming its reversal film counterpart. The pioneers in the use of chromogenic prints and in the use of color photography as a whole in fine-art were photographers such as Ernst Haas ,  which was profiled by the Museum of Modern Art in its first single-artist exhibition of color photography in After exposure, the silver image is developed or reduced by a color developer. In its reaction to the print, the color developer is oxidized in the areas of exposed silver, and subsequently reacts with another chemical, the dye coupler, which is present throughout the emulsion.
Playle’s: Real Photo Postcards, How to Identify and Date Real Photo Vintage Postcards
Guide to Real Photo Postcards This guide is meant to aid the collector in identifying and dating real photo postcards, and to act as a reminder that it is impossible to do so with great accuracy. Although real photo postcards were made in a variety of ways, they hold one identifiable feature in common. The tonalities of photos are completely continuous to the eye producing true greys, for they are created by the reaction of individual photosensitive molecules to light rather than the transfer of ink from a plate.
In printed images the grey areas are usually made up of black marks that are spaced to create the optical illusion of greys. Though most of us today are familiar with the concept of photo grain, this is mostly because we have experienced very large prints made from small 35mm negatives. But even here the effect is more of a softening of detail than a observable texture.

After copies were pressed onto the paper, the paper entered the cabinet under the copier, where it dried on a large roller. An attachment was used to cut dried copies off the roll. Numerous companies produced roller copiers over a period of three decades. For example, Plate 11B shows a Rapid Duplicator that was advertised in Copies could be made more quickly with a roller copier than with a letter copying press. It was claimed that nearly papers could be copied in two minutes with a roller copier.
Any development in the wash may have caused a slight veiling or fog in the highlights of the print so development had to be stopped abruptly. With regards to the Negative film process, an increase in density in the shadow areas due to developer carry-over, was not unfavourable. The optical sound track was printed onto the Colour Positive Film from a Black and White Sound Negative, exposed through a blue filter.
All silver halide from the picture area was then removed in the fixing bath, leaving the exposed silver halide in the black and white sound track area.
Photography is the art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art.
Kindred Spirits each and every one. Above all else there is the generosity of contributors whose photographs of steam days from fifty-odd years ago make this site possible. Indeed the remit has always been to give a voice to new talent on the Internet Now there’s a conundrum! The talent to which I am referring are gentlemen born and raised during the s and s, who spent the best part of their youth dashing around the country in the pursuit of loco numbers or taking photographs of trains just for the fun of it.
They did it for themselves and no one else. I’m talking about that quintessentially British s curiosity called train spotting; a hobby demanding such high levels of commitment and pricey long-distance train travel, that it’s surprising it ever got off the ground in the first place, especially during the penny-pinching post-war years.
Even odder still, railway photography – a natural adjunct to spotting – didn’t come cheap either, yet it became one of the fastest growing pursuits for boys – and hallelujah for that!

Only one colour developer and one bleach bath were required.

Developing My first bit of advice is to figure out whether or not you want to buy and use these cameras, or simply display them on a shelf. The number of people shooting film has significantly decreased in the last 15 or so years, but there is still enough of a loyal following that it is still possible to get film cheaply.
If you have no interest in actually using old cameras, then by all means go hog wild and just buy anything you think looks cool.

Light-field camera Digital methods of image capture and display processing have enabled the new technology of “light field photography” also known as synthetic aperture photography. This process allows focusing at various depths of field to be selected after the photograph has been captured. These additional vector attributes can be captured optically through the use of microlenses at each pixel point within the 2-dimensional image sensor.
Every pixel of the final image is actually a selection from each sub-array located under each microlens, as identified by a post-image capture focus algorithm. Devices other than cameras can be used to record images. Trichome of Arabidopsis thaliana seen via scanning electron microscope. Note that image has been edited by adding colors to clarify structure or to add an aesthetic effect. Heiti Paves from Tallinn University of Technology.
Other[ edit ] Besides the camera, other methods of forming images with light are available. For instance, a photocopy or xerography machine forms permanent images but uses the transfer of static electrical charges rather than photographic medium, hence the term electrophotography. Photograms are images produced by the shadows of objects cast on the photographic paper, without the use of a camera.
Objects can also be placed directly on the glass of an image scanner to produce digital pictures.

He had a bookcase full of old Kodak paper boxes in which he stored his negatives, some of which had both codes printed on the labels. Kodak VELOX paper was a very slow printing paper, producing a blue-black image, suitable for contact printing only, where the negative is placed in contact with the paper to produce a print of the same size.
Kodak discontinued the manufacture of Velox paper in They could also be used for contact printing. Bromide paper gave a neutral black image.

‘So you wanna work in Movies’ is a real-life guide to working in feature files, a response to the question: How do I get into Movies? by Oliver Stapleton BSC.
So you have to ask yourself the question: Am I Any Good at Anything? I’m totally useless at everything This is not necessarily a problem as some people working in the industry are totally useless. Some years ago I was rude about various jobs, but then I realised there is no point in being offensive! Some people who work on the floor, i.
I’m totally useless at everything but I am willing to learn Now this is much better. Unfortunately modern schooling means that most of us are never “first”.

He says that he found the sign “in the loft of one of my father’s chemist shops. I was probably no more than 14 years old when I came across it clearing out that roof space which had been untouched for decades. I’ve always been quite a strong athletic person, even as a child, so my dad always found good use for my energy and enthusiasm by giving me the tough dirty jobs nobody else wanted! It’s now been in my possession for 20 years. He sold his chain almost a decade ago and it’s really the only thing I have to remind me of the shops, so sentimental value is quite high”.

Features and Benefits of the Cobra S3 Max fairway: A new 25 larger face increases the size of the Sweet Zone for higher COR and increased overall distance. The Pro S model has a. If you want distance, it s hard to imagine you could do better than the Cobra S3 s. The S3 proved to be the longest iron we ve ever tested. Our testers not only rated the S3 as the longest, but also the most accurate irons we ve tested this year. Cobra S3 Irons Written By: GolfSpy T Within the last year we ve had the opportunity to review a couple sets of Cobra irons.
The S2 Forged iron was a big hit with our testers particularly those concerned with distance, and the Cobra Pro CB, which we reviewed as part of our head to head battle of the cavity back irons, posted the highest subject score of any iron in the test while finishing second overall. Given how well the irons we tested last year were received, as well as the S2, S3, and ZL drivers performed, it should almost go without saying that we were anxious to see how Cobra s latest game improvement iron would perform.
Just like the S3 driver, they feature what Cobra calls E9 technology, which introduces the concept of sweet zone bigger than a sweet spot to maximize performance across the part of the face where golfers tend to actually make contact with the golf ball. Taking a look at the specs below and you ll see that Cobra appears to have gotten themselves caught up in the distance is everything mindset.
It s hard to blame them as just about every manufacturer offers at least one set of extra long irons with jacked up lofts. All we re really talking about here is the number stamped into the sole.
