This film is ideal for student work, casual photography, experimental photography, pinhole cameras, and Holga/Lomo-style expressive shooting.
Important! This black and white film should not be processed as a color film. Color processing uses a bleach step which will remove the image. Be sure your local lab develops it in black and white chemistry and does not subject it to a bleach process. Excellent mail-order processing for this film is available from 120PROCESSING.COM and Blue Moon Camera.
UPDATE: although most users express satisfaction with this film, some users report defects, in the form of background mottling, and it seems like many rolls have image artifacts related to the backing paper, which show up under enlargement in the form of faint rings or circles. I suspect these defects, which were not apparent when we first stocked this film, may be related to its age.
This will not be an issue for experimental photographers, or indeed for most students or casual photographers. It will not affect images enlarged to conventional snapshot sizes (for example, 4x6 inches).
However, if you are a serious art photographer, attemptiing to create high-quality, high-enlargement images, this outdated film will be risky for you.

This is a good quality, inexpensive black and white roll film made in China by the SMPIC Photosensitive Materials Factory of Shanghai, an industry leader with more than 40 years of experience in making photographic materials.
The parent company, SMPIC , was founded in 1973 and is currently joint venture partner in China with Polaroid and Fuji Xerox, making cameras and office machines, and is also a major producer of high-quality optical glass.
SMPIC makes their photosensitive films to very high standards of quality, easily the equal of the major international brands. Each boxed roll is heat-sealed in a paper-plastic laminate high-barrier wrap, and can safely be stored in a refrigerator or freezer without worrying about moisture damage.
I have tested several rolls, outdoors and under controlled lighting. My personal experience is that GP3-100 compares favorably with Kodak Plus-X and Ilford FP4-Plus. Anyone who has used Efke PL100 will be equally satisfied with GP3-100, and will appreciate GP3's heat-sealed, moisture-proof packaging, as opposed to the Efke unsealed wrapper.
If you are not trying to use this film for highly-enlargeable, high-quality fine-art photography (see the "Update" above), I have no hesitation in recommending this fine film, despite its low price. David Foy
