Profile notes

Shanghai GP3 100 is produced by Shanghai Jiancheng Technology Co. Ltd (SHJC) in China. Despite input data listing it as ISO 400 C41, it is a panchromatic BW negative film rated at ISO 100/21°. The emulsion is silver-rich with controlled grain, high contrast, deep blacks, and bright whites, suited for enlarging and scanning. Available in 35mm, 120, 220, and sheet formats. Standard BW chemistry applies. The film can be handled under deep red safelight, suggesting some orthochromatic character at lower wavelengths, though it is fully panchromatic.
