The Polaroid SX-70 uses SX-70 film, an integral instant film known for its unique low ISO and development process. This classic film type, resurrected by the Impossible Project (now Polaroid BV), is specifically designed for the SX-70 camera’s internal mechanics and exposure requirements.
Understanding SX-70 Film
The Polaroid SX-70 camera, a marvel of engineering introduced in the early 1970s, relied on a revolutionary type of instant film: SX-70 film. This film is not just any instant film; it’s a carefully calibrated emulsion and chemical system designed to work flawlessly with the camera’s light meter, development mechanism, and optical system. Its defining characteristic is its relatively low ISO rating, resulting in images with a distinct aesthetic. The self-developing aspect meant that each shot was a complete package, with the chemicals necessary for processing contained within the film pack itself. This eliminated the need for messy developing processes and darkrooms, ushering in a new era of accessible and instant photography.
The Resurgence of SX-70 Film
For a period, after Polaroid discontinued production of SX-70 film, its future looked bleak. However, enthusiasts refused to let this iconic film die. The Impossible Project, later rebranded as Polaroid BV, stepped in to recreate and improve the SX-70 film formula. This resurrection not only saved the SX-70 camera from obsolescence but also reignited interest in instant photography as a whole. Polaroid BV’s commitment to preserving the legacy of instant film ensures that photographers can continue to experience the unique charm and creative possibilities offered by the SX-70 camera and its dedicated film. The current SX-70 film formula boasts improved color rendition and stability compared to earlier iterations, addressing some of the initial challenges faced during the Impossible Project era.
Working with SX-70 Film
Shooting with SX-70 film requires a certain understanding of its characteristics. Its low ISO makes it more sensitive to bright lighting conditions. Often, using natural light during the day produces the best results. Overexposure can easily wash out the image. Understanding your SX-70 camera’s light/darken wheel is crucial. A common practice is to begin by adjusting the wheel slightly toward the darken setting, then adjusting as needed to achieve a balanced exposure. Patience is key during the development process, as the image gradually appears over several minutes. Shielding the developing image from direct light during this period also helps to ensure optimal color and contrast. The unique, somewhat unpredictable nature of the film contributes to the distinctive aesthetic that has made the SX-70 camera so beloved.
FAQs: Diving Deeper into SX-70 Film
Here are some frequently asked questions to further expand your knowledge of SX-70 film and its use with the Polaroid SX-70 camera.
H3 What is the ISO of SX-70 film?
SX-70 film has a relatively low ISO of 160. This low sensitivity makes it ideal for well-lit environments but challenging in low-light situations.
H3 Can I use 600 film in an SX-70?
No, you cannot directly use 600 film in an SX-70 camera without modification. 600 film has a higher ISO and requires a different voltage. Using it directly will result in severe overexposure. However, you can use a neutral density filter specifically designed for this purpose, placed over the lens to reduce the amount of light entering the camera, effectively “tricking” it into thinking it’s shooting with SX-70 film. Alternatively, you can modify the camera itself to accept 600 film voltage, but this is not recommended unless you are experienced with electronics.
H3 What are the differences between SX-70 film and 600 film?
The primary difference is the ISO rating. SX-70 film is rated at ISO 160, while 600 film is rated at ISO 640. This means 600 film is significantly more sensitive to light. 600 film cartridges also incorporate a larger battery, designed for cameras that do not power the motor with the film pack like the SX-70 does.
H3 How long does it take for SX-70 film to develop?
SX-70 film typically takes 10-15 minutes to fully develop at room temperature (around 70°F or 21°C). Development time can be longer in colder temperatures.
H3 How should I store SX-70 film?
It’s best to store SX-70 film in a cool, dark, and dry place before use. Refrigeration is acceptable, but avoid freezing the film. Always allow the film to reach room temperature before loading it into the camera.
H3 What are common problems when shooting with SX-70 film?
Common issues include: overexposure in bright light, under-exposure in low light, color casts (often due to temperature or age of the film), and uneven development. Understanding your camera’s light/darken wheel and light conditions is key.
H3 Where can I buy SX-70 film?
SX-70 film is available from Polaroid BV directly, as well as from many photography retailers, both online and in brick-and-mortar stores. Major retailers like Amazon and B&H Photo Video also carry it.
H3 How many photos are in a pack of SX-70 film?
A standard pack of SX-70 film contains 8 photos.
H3 Can I use expired SX-70 film?
While you can use expired SX-70 film, expect unpredictable results. Colors may be faded or distorted, and the image may be significantly degraded. Expired film should be stored carefully, and compensating for the age with exposure settings might improve the results, though it is never guaranteed.
H3 What is the best way to protect my SX-70 photos as they develop?
Shielding the photo from direct sunlight during development is essential to achieve optimal results. A dark slide, or even just placing the picture face-down on a flat surface, can help.
H3 What is the typical cost of a pack of SX-70 film?
The cost of SX-70 film varies depending on the retailer and any ongoing promotions. Currently, you can expect to pay around $20-30 per pack of 8 photos.
H3 Does SX-70 film come in color and black and white?
Yes, Polaroid BV currently offers both color and black and white versions of SX-70 film. Each provides a different aesthetic and allows for creative experimentation.
By understanding the nuances of SX-70 film and practicing good shooting habits, you can unlock the full potential of the Polaroid SX-70 camera and create stunning instant photographs. The magic of instant photography lies not just in the immediacy of the results, but in the unique character and imperfections that make each SX-70 image truly one-of-a-kind. The legacy of this iconic film and camera continues to thrive, inspiring photographers of all levels to embrace the art of instant creation.
