Modifications for the Use of SX-70 Cameras with 600 Film

Posted 09 May 2012 | By Anonymous | Categories: Polaroid | No Comments

If you happen to have an old SX-70 camera lying around, you’re in luck. SX-70 cameras can take Polaroid 600 film with an easy modification. Folding SX-70 cameras are superior to 600 cameras as they have optional neutral density filters, glass lenses and a starting focal length of 10.4 inches.

The modification to use 600 film with SX-70 cameras is not a modification to the camera, but to the film cartridge and is simple to do.

What you will need to load 600 film into an SX-70 camera:

  • Polaroid SX-70 camera
  • Polaroid 600 film
  • A protective sheet from an old pack of Polaroid 600 film or old Polaroid photograph
  1. Open the camera.
  2. Take the old protective sheet or photograph and hold it under the bottom of a new pack of Polaroid 600 film. You need to cover all four of the plastic bumps on the bottom of the film cartridge.
  3. Holding the old protective sheet or photograph under the cartridge, insert the cartridge into the SX-70 camera.
  4. Remove the old protective sheet/photograph and close the camera.

The problem with using 600 film in an SX-70 camera is that SX-70/Time Zero film was only 150 ASA compared to 600’s 640 ASA and SX-70 cameras were, of course, manufactured for SX-70/Time-Zero films. When shooting in a low light situation, there is no problem; all you need to do is adjust the camera’s exposure controls and the difference in ASA will take care of the rest. Otherwise, there are easy solutions for the ASA problem.

The first is to use the SX-70 Blend film, which is made by, but not supported by Polaroid. The second is to use a factory issue 2-stop neutral density filter, which this will darken the image in the viewfinder making it more difficult to focus. The third is to use a semi-disposable filter called a PackFilter®., which are ±2 neutral density filters specially tailored to give 600 film a look similar to Time-Zero film.

How Instant Integral Films Work

Posted 09 May 2012 | By Anonymous | Categories: Polaroid | No Comments

The chemical components of Polaroid integral films are complicated and privileged information known by a very small group of people. The workings of the films however, are not as secretive.

The films consist of three basic layers that, together, make up the film. The first layer is the transparent sheet (the transparency) that light travels through to expose the film and through which the final image is viewed; this layer is not light sensitive. The second layer is a negative, which is made of a film base that contains silver halide grains, image dyes and spacer layers. The third layer is a foil pod containing the reagent that develops the film.

After pressing the shutter release and exposing the film to light, the camera ejects the film through the camera’s rollers, which breaks the foil pod of reagent and spreads the reagent over the film evenly. In the reagent lies white pigment, opacifying dyes, alkali and other active materials. This process can take less than a second.

The negative has three layers of light-sensitive silver halide grains as well as a timing layer which controls a layer of polymeric acid for image stabilization. Below each layer of silver halide is a dye developer layer. The dye developer layer under the blue-sensitive silver-halide is yellow which is the compliment of blue; the layer under the green-sensitive is magenta, which is the compliment of green and the layer under the red-sensitive layer is cyan, the compliment of red. When these dyes combine, they can recreate the colors of the original subject that was photographed.

When a picture is taken, light enters through the lens to reach the negative. If the light is white meaning that there are equal amounts of all three primary colors, it exposes all three layers of silver-halide. Blue light will only expose the blue-sensitive layer and the yellow layer acts as a filter, preventing the light from reaching the other layers; green light will only expose the green-sensitive layer and the magenta layer acts as a filter, preventing the light from reaching the red layer; red light exposes only the red-sensitive layer and black is created in the absence of color so it exposes none of the layers.

In the first of two development steps, the reagent quickly penetrates all the layers of the negative, ionizing and solubilizing the dye developers. The dye developer becomes trapped in the negative layers but in the unexposed areas, dye developers are free to migrate to the image-receiving layer. In exposed areas, blue light will cause the yellow dye to be trapped in the blue-sensitive layer; green light will cause the magenta dye developer to be trapped in the green-sensitive layer; red light will cause the cyan dye developer to be trapped in the red-sensitive layer. This first step is completed in less than 20 seconds.

In the second step, which is the remainder of the developing time, the dyes migrate through the emulsion and opacification layers where they will be viewed through the transparent sheet against the background made of white titanium dioxide. The opacifying dyes that were used to protect the negative from further exposure to light become colorless as the polymeric acid layer in the negative reduces the pH of the system, which activates when the reagent penetrates the timing layer. As the pH balance is reduced the image appears to ‘develop’ before your eyes but really, the image has already developed under the opacifyng layer and is now becoming visible.

The time from the film ejected from the camera to the completion of the development process is approximately 4 minutes but can vary (as much as ±2 minutes) depending on environmental conditions.

Digital photography? You wish to spend  a couple of hundred pounds on a camera that doesn’t even give you a picture in your hand until you’ve downloaded it to your computer and then printed it on your trash (or very expensive) color printer? Go ahead. But I’m sure I’m a lot more happier with my Polaroid 600 instant camera, with that oldskool polaroid 600 film. The prints are instant, which means that each picture is a unique artefact. Your photo is not a print of a negative which survives elsewhere; it is a really unique picture. And they are square, which is a lovely shape for a picture.

The polaroid 600 films are very overpriced, that’s really sad. There is some project called the impossible project that want’s to return the polaroid 600 film. Polaroid is also bringing back the polaroid instant camera with a funky new design, that also works on the oldskool polaroid 600 film! So I consider the polaroid 600 film will come back!

First of all get back in the time. On 21 February 1947, Edwin Land, the founder of Polaroid Corporation, demonstrated instant photography to the Optical Society of America. The first commercially-available instant camera, the Polaroid Land Camera Model 95, was in the stores before Christmas of the following year. The first films were sepia-tone; black-and-white Polaroid film was presented in 1950, but for color films we had to wait until 1963.

Since then, Polaroid has slowly honed its range of popular instant cameras. In 1977, the OneStep Land Camera was a big hit, and it held on for around four years which made the Polaroid OneSetp the biggest-selling camera of any type in the world. Throughout the 1990s, Polaroid have made 600 series cameras (that worked on polaroid 600 film) which have varied in outward appearance very slightly, but have a similar basic design.

Throughout its history, Polaroid has given some resources to photographer-artists in exchange for feedback about its products so they could improve them. The first of these, landscape photographer Ansel Adams, was hired by Edwin Land as a consultant in 1948. In his autobiography, Adams recalled that Land was “convinced that images can be as effective as words, and that every person has a latent ability to make effective contact with another through visual statements”.

Since each polaroid picture is very unique, people went to experiment with it. They experimented with their photographs, they used chemicals for it, but also a very intensive light or heat source and they used drugs for it also….
The ‘artist’s studio’ part of the Polaroid website tells you about some of this. There is also a nice book, Innovation/Imagination: 50 Years of Polaroid Photography (Abrams, 1999), for interested people to gaze at.

The new digital minded people can always scan their polaroids, so that they can be manipulate the polaroid with for example Photoshop and put it on the internet, or whatever. If you don’t have a scanner yourself, libraries, colleges and community centres have them, or reprographics shops will charge you an annoying but relatively small amount of money for scanning.

I went through my storage and found my old Polaroid camera that I used to love so much. I am going on a road trip through the east US and Canada and I want do a photo project with my Polaroid camera and my digital camera.
I want to get in touch with someone who would possibly be interested in supplying the Polaroid film because it is expensive and hard to find. They in return could get the photos for publicity. I want to bring Polaroid back!

This Video explains how sellers mislead buyer by making it look like they have tested their camera on Ebay before selling by putting a photo in the listing that the camera has taken. Not all sellers do this but it is extremely hard not to waste film and do this.
