<p>Craig I purchased 1 roll of it (for almost nothing) for the sole purpose of testing my camera. I do not intend on withdrawing my support for quality film manufacturers in order to shoot rubbish like Shanghai GP3.<br> Thanks John for your help.</p>

<p>Hi guys, I just shot a roll of a cheap Chinese 120 film called Shanghai GP3 ASA 100 (expired, not sure how long ago) to test out my Mamiya RB67 for light leaks. I developed the film in Ilford ID-11 for 14 minutes, 20 degrees c and a ratio of 1+1. The negatives came out pretty poorly (poor contrast, grain)but the main concern is the backing paper from the film is visible in the negatives! I am confused as to why it is appearing. Is it because the film is too old? Here are some of the scans (low res to test) and a picture of the film backing paper.<br /> If you have any ideas/suggestions please post below!<br /> Thanks!<img src="http://i.imgur.com/HyeL1RB.jpg" alt="" width="1661" height="1114" /><br /> <img src="http://i.imgur.com/00Xbj8q.jpg" alt="" width="1661" height="1114" /></p> <p><img src="http://i.imgur.com/h2GgnTN.jpg" alt="" width="540" height="960" /></p>

<p>Thanks! It is Gp3</p>

<p>I need help identifying the film below. It's a black and white 120 film, that's all I know.<br> <img src="http://i.imgur.com/yxGRFrL.jpg" alt="" width="720" height="960" /></p> <p><img src="http://i.imgur.com/ZZ6VguV.jpg" alt="" width="720" height="960" /></p> <p><img src="http://i.imgur.com/p6Ro2zE.jpg" alt="" width="720" height="960" /></p> <p><img src="http://i.imgur.com/k7QbSog.jpg" alt="" width="720" height="960" /></p>
