Can You Use 600 Film In Sx-70 Onestep Camera

Originally Polaroid SX-seventy and Polaroid 600 film had different chemical makeups to set them autonomously. A user may have chosen one over the other based on need or application. Specifically, many people loved SX-lxx for it'due south gelatin base components that allowed for post-exposure manipulation of the photo. Since production was restarted in 2008 by the Impossible Project (who would go on to become the Polaroid you know today), the chemical makeup of 600 and SX-70 film is at present largely the aforementioned, leaving a slight variance in film speed as ane of the remaining differences.

SX-70 has always been a bit more demanding than 600 film. Being slower speed film (SX-70'southward 160ISO vs 600'southward 640ISO) information technology requires external flashes or a longer exposure time which can result in burry images if taken without a tripod. Every bit a faster picture, 600 responds meliorate in depression-lighting conditions and may not require a wink or perfectly steady mitt. With SX-seventy'south defining features removed, many people are outset to explore 600 film — and all of its advantages — every bit an alternative option to fuel their SX-lxx cameras.

Because information technology's really all nigh the cameras. While the SX-70 flick stock may not be the same as it once was, the cameras meant to shoot it are still some of the finest devices in the world of instant photography. Even after nearly 50 years, Polaroid's SX-70 folding cameras offering fantabulous focusing, unique depth of field and exposure control unmatched past other instant camera models. Except for the increasingly rare SLR 680 and 690, these features weren't seen in the 600 camera line, which makes converting a photographic camera from SX-70 to 600 an attractive proposition. It combines the best of both worlds — 600's flexibility with the enhanced features of a folding SX-70 camera.

Tin can I shoot 600 pic in my SX-70 without a conversion?

Y'all can, but it's non the optimal experience. The simplest fashion by far is to just use a neutral density (ND) filter. These tin be found online for about $xv and are installed direct on top of a film pack. The problem with ND filters is that they merely change the film's sensitivity simply do nada to the camera'south shutter speed. Every bit a result, the camera volition yet perform poorly in depression lighting scenarios without a tripod or a wink, and you may end up disappointed with blurry photos of your most precious moments. There are besides ND filters bachelor that are installed over the lens of an SX-lxx photographic camera. These will take the aforementioned outcome every bit the ND filters higher up — information technology will alter the film sensitivity just not the shutter speed, resulting in the potential for blurry images in low-light.

Another conversion that sometimes comes up is the electric middle filter 600 conversion (the electrical eye is the sensor to the correct of the lens when you're looking at the camera). It'south more of a hack than a true conversion, executed by removing the original electric eye filter in the photographic camera and replacing it with a completely articulate filter or nix at all (which nosotros recommend never doing as it profoundly increases the chance debris, moisture or other contaminants will detect a manner inside your photographic camera). The idea backside it is that messing with the center and then cranking the exposure punch will play tricks the photographic camera into a faster shutter speed more appropriate for 600 picture show. Unfortunately information technology can be both highly inaccurate, due to variances in old photograph diodes, and as well compromise, or completely remove, the power to calibrate for dissimilar lighting situations with the exposure dial.

How Retrospekt'due south 600 conversions work

So what makes Retrospekt'due south 600 conversion unlike from anyone else's? We certainly can't say nosotros've had the opportunity to review what anybody out in the world is doing in regards to SX-seventy to 600 conversion services. However, we tin can say what nosotros know most our procedure and what sets it autonomously.

At its core, our process relies on recalibrating how the camera reads light. On the surface the conversion process itself is not super difficult — assuming one has all the right parts, knows how to accept apart and reassemble a camera and possesses practiced soldering skills. However, all cameras historic period differently. No 2 are exactly alike and, with decades of history behind them, the condition of their internal parts can vary dramatically from camera to camera. Most important of these parts is the light sensitive photodiode which controls the exposure. Since the conversion to 600 moving-picture show requires changes to the camera's hard-coded circuitry, it is essential to know how the photodiode is currently performance in each specific camera at the time the conversion is made. We can't solely rely on Polaroid'due south specifications from what it was supposed to be in the 70s. To practise this correctly, the advisable exam equipment needs to be available for the technician.

To solve this trouble, nosotros accept developed our own proprietary examination equipment that allows us to get the exact hardwired parameters even if they have been altered due to oxidation of the photodiode. We then map these numeric values against conversion tables and matrices we have created with years of data compiled from over x,000 SX-70 cameras. In this regard, the data and feel nosotros have to describe from is simply unmatched.

Without this equipment or data, someone performing a similar service has to rely largely on guess and cheque work. An aligning is made, a motion-picture show is taken, the photo develops and is analyzed, and the whole process starts once again. This process continues repeatedly until the last image is dialed in to adequate standards. Unfortunately, the constraints of fourth dimension and movie price may crusade those using this approximate and check method to pass off close-enough as a fully-calibrated final production. The guess and check method as well brings with information technology two other potential pitfalls: exam pic quality and personal subjectivity. Every batch of pic from Polaroid is slightly different. While nearly of the fourth dimension the variance should be negligible, this method could potentially cause a photographic camera to be calibrated to an exposure balance that isn't completely neutral. It's besides of import to take subjectivity out of the equation. If we only had an in-person verification, then outcomes could change from technician to technician based on preference rather than on numeric and visual parameters.

Some of these variables may be okay if you are doing the piece of work yourself and you have the time and don't mind spending the coin for film to burn down through when testing. However, if you pay a company to do this work, you lot want to know your camera isn't being calibrated based on one person's idea of a proper, middle-of-the-line exposure.

As part of our procedure, nosotros do both. We trust our equipment to go united states of america to where we need to exist, simply nosotros always brand certain everything is working with a last film test verified past our technicians.

Tin I shoot both 600 and SX-70 flick later on the conversion?

People often ask, "is your SX-seventy to 600 conversion service a permanent conversion or will the camera be able to switch betwixt 600 and SX-70." The short answer is no, the conversion is a change to the camera'southward difficult-coded photo sensor. Information technology's a semi-permanent service (it'll terminal indefinitely unless you lot have it converted back) requiring the photographic camera to be taken apart past a camera technician who volition swap some circuits then utilise proprietary timing equipment to alter the shutter speed of the camera to accurately shoot 600 picture show.

Why is converting to 600 better than using filters?

Just put, filters make 600 film deport like SX-70 movie, conversion makes SX-70 cameras comport like 600 cameras. While filters only change the motion picture sensitivity, the hard-coded 600 conversion changes the exposure characteristics while returning the camera's default exposure to a neutral baseline. This allows the user to engage the photographic camera in more than complimentary form, hand held utilize without every bit much dependence on a tripod or flash bars.

In my personal stance, the best photos I take seen with the folding SLR cameras are when the photographer takes advantage of ambience light and avoids wink bars, which tend to blacken the background and minimize the beautiful depth of field one would otherwise have with ambient lighting only (this is 1 of the key features that set SX-lxx folding cameras apart from about all production 600 models). There is certainly something beautiful and mannerly virtually setting up a camera on a tripod and composing a photograph just correct, but with iv ambrosial nieces to photograph all the time I desire something handheld and simple. Because of that, my 600 converted sonar folding camera volition remain my tried and true choice.

Interested in photographic camera conversion? Nosotros offer a stand-lone SX-lxx to 600 conversion service for Polaroid folding cameras. For cameras needing a lilliputian more beloved, we also have a total repair/refurbish service to convert your photographic camera to 600 while making other repairs that can bring even non-functional cameras back to working order.
