From left to right:
NC500 NC400 Shanghai(Shenguang)400
Comparing Shanghai's emulsion with NC series,I think It's NC400 that re-pack by JC Film Co Ltd.
Anyway,this film is $0.4 more expensive than Shanghai.
InovisCoat's film cartridges are recycling so in this way,Shanghai's expense is acceptable because JC Film use new cartridges.Under NC400's sticker,it's a cartridge made in China that had been sold with 5207 film.That 5219 sticker is designed by me,as to imitate Portra.They share same cartridge design.
JC Film had produced new cartridges but flaws in manufacturing processes are everywhere.I don't mind them,anyway.
Additionally,in my point of view,NCs' and Shanghai's designs may be not perfect enough,a practical cartridge should like Kodak's,whose info can be see from the window of cameras' back.
