It features a traditional cubic-grain silver-rich emulsion with fine grain, high contrast, and excellent sharpness — suitable for street, portrait, and landscape photography.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between the 24 and 36 exposure versions?\u003c\/strong\u003e\u003cbr\u003eA: The emulsion is identical — the only difference is the number of frames per roll. The 24-exposure roll is shorter and suits photographers who prefer to develop more frequently, shoot in shorter sessions, or want a lighter load when travelling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can Shanghai GP3 100 35mm be pushed?\u003c\/strong\u003e\u003cbr\u003eA: Yes. GP3 100 pushes reliably to ISO 200 (+1 stop) and ISO 400 (+2 stops) with extended development. It can also be pulled to ISO 50 for reduced contrast in bright light. Refer to the Massive Dev Chart for specific developer times.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What developers work best with GP3 100 35mm?\u003c\/strong\u003e\u003cbr\u003eA: GP3 100 works well with D-76 (1:1) for balanced grain and tonality, HC-110 (Dilution B) for sharpness and speed, Rodinal (1:50) for acutance and classic grain, and ID-11 for fine grain. Stand development in Rodinal (1:100, 60 min) is also popular.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is Shanghai GP3 100 still being made?\u003c\/strong\u003e\u003cbr\u003eA: Yes.
