Many people want their Polaroid SX-70 camera (Introduction of SX-70) can use Polaroid 600 film or the PX680 / PZ600 film from the IMPOSSIBLE project store. However, as the iso/ASA of the 600 film is different (600 vs 100) from the SX-70 time zero film (or the IMPOSSIBLE project PX-70 PUSH!). If we use the 600 film directly on the Polaroid SX-70 camera, the pictures will be over-exposed. Therefore, we have to do modification to convert the SX-70 camera to uptake 600 film

There are many ways to convert the Polaroid SX-70 camera, but all methods are based on the same principle – to reduce the light intensity reaching the film. Some people would change the photocell of the light meter, some people may apply filters on the integral film. However, the simplest (and the reversible) way is to attach a ND (neutral density) filter on the lens. In future, if you would like to use back the original SX-70 (or PX-70) films, you just need to remove the filter. Very easy

This kind of ND filter is very common, you can easily find it on web (e.g. eBay) or camera shops

Usually, it is an 1-stop ND filter with a sticker, what you have to do is just stick the ND filter to the front part of the lens

Unfolding the SX-70. If you are using SX-70 SONAR OneStep with auto-focus function, please change to manual focus mode

Dial the focusing dial to make the lens move forward to the front end

Simply attach the ND filter to your SX-70. However, as SX-70 is a SLR, so the light reaching the viewfinder will be reduced as well. It is the drawback of this method
