:: things i like :: impossible px shade
If you use impossible film, you have to shield it from the light for at least the first 4 minutes for the image to appear. Sometimes, I forget or I can't get the image into my camera bag fast enough and I'll lose the image. <super loud sigh> Then, I found out that they invented the Impossible PX Shade. It slips into your SX-70 front slot and blocks every image from the sun. Brilliant!
