AP EXCLUSIVE: Mass production of new instant film designed to be used on Polaroid?s most popular consumer cameras, the 600-series, has been put on hold, it has been revealed.

Earlier this week Dutch firm Impossible BV announced the launch of new black & white films for use in traditional Polaroid cameras.

The firm stated that a ?limited? edition of the new PX 100 and PX 600 Silver Shade films will go on sale from tomorrow, via the Impossible website, priced ?18 per pack.

In a change of plan the company has since told Amateur Photographer that only the PX 100 version will go on sale tomorrow.

PX 100 is designed for Polaroid SX-70 cameras, while PX 600 is made to be compatible with 600 series models (pictured).

The film is eventually due to go on sale at John Lewis stores in the UK and The Photographers? Gallery in central London where a ?launch event? will take place on 27 March. Colour film is expected to be available this summer.

However, it seems Polaroid 600-series camera owners will have to wait for compatible film to become available.

Impossible Project spokeswoman Marlene Kelnreiter today told us that ‘unexpected demand’ for PX 100 has forced the firm to delay production of PX 600.

?The PX 600 is not available yet as we currently need all our capacities to produce PX 100 Silver Shade films.?

She added: ?As soon as we have produced enough PX 100, we will start mass production of the PX 600 Silver Shade.?

Kelnreiter told us she expects production of PX 600 to start in ‘mid-April’.

PX 600 Silver Shade will carry an ASA [film speed] of 600.

Photographers can use PX 100 film but exposure will result in ?very dark images,? explains the manufacturer on its website.

Kelnreiter said the firm has received a ?surprising amount of pre-orders? for the PX 100 film.

News of the instant film revival came two years after Polaroid announced it was shutting down its film manufacturing plants in the United States.
