Via photoscala.de. The Impossible Project have now launched the sale of the ‘First-Flush-Edition’ of their new PX 600 Silver Shade instant film for Polaroid 600 instant cameras, four weeks after the first packs of PX 100 started shipping. The film is said to deploy ‘detailed monochrome characteristics’ as well as being ‘precise and sharp’. Packs with eight sheets ship for 18 €.
photoscala also have two PX 600 sample pictures, and they do indeed look very promising. (A lot better than the PX 100 samples discussed earlier!)
EDIT: ephotozine also have the news, in English.
