As our High Street is now

Pete it might be just the scan but when saw this I assumed that this was probably the same film is in your two pictures and yet instantly this one looked less grainy and when I checked it was indeed a different film. You haven't specified what it is other than just an "Australian Sunny 16 400 film" but it does look less grainy. Almost surprisingly less grainy given the speed has only dropped by a stop

YES -- it is 'newer' than the Fuji Press 800 and it did come out less grainy . My YouTube Mate Roger Lowe was sent it but he does not shoot 'Colour' only B&W so he sent it to me together with a Japanese 'Home Market' Fuji 200 with identical Cassette Pot . I went onto the web-site of the Australian Company that sell the 'Sunny 16' HILVALE.COM.AU and it was very interesting but their Prices for FILM there are horrendous !

Thanks Pete. Yes I think our Aussie friends have a genuine gripe about prices that they are asked to pay in OZ
