Hello, Is it possible to use hypo check with an alkaline fixer such as TF4 or TF3? In such case, would it work the same as with an acid fixed? Is it recommended? Thank you all

Thanks a lot Bob! I'll keep using my lead bags : ) I started to worry about X rays after reading an interview of Sebastiao Salgado, in which he said that he was no longer shootting film because gate x-ray machines where damaging his exposed film. Apparently, the fogging was so severe that the images were unusable. "Unsusable" to his standards might be just that the film contrast decreases. Years ago I have been haunted by that... Some time ago I decided to resign and just not worry anymore...

Hello. Some weeks ago I made an experiment with the X ray machine of a small airport (it seemed like a brand new machine, unlike those old machines with supposedly ultra powerful x ray radiation). After I had passed my luggage with my exposed film in a Film Shield 20 xpf lead bag, I took my rolls out of the lead bag and asked the X-ray machine operator if I could run a small experiment. I was able to do that because 1) the airport was almost empty and 2) the lead bag had created suspicion when I passed through the X-ray machine for the first time. (Since I own the lead bag, it has ALWAYS created suspicions among the x-ray machine operators). So, I grabbed my keys, I threw them into the lead bag and I passed it all through the x-ray machine again... Do you know what happened? I could watch my keys in the x-ray machine screen, inside the lead bag. They were opaque, but the conclusion is that the x-ray machine did could see through the Film Shield 20 xpf lead bag. Second conclusion? The Film Shield 20 xpf lead bag is worthless and, as far as I know, it is one of the thickest lead bags in the market.

I suggest you to NEVER use Youxin Ye's services. He is a good person, but he is an amateur after all. He accidentally removed the coating of some Leica lenses I sent him (repairing those lenses ended up being terribly expensive because of Youxin's inexpertise). In addition, he does not know very well which lubricants to use. IMHO he is an amateur and thus he can cause terrible damage without even being aware of it. DAG or Sherry Krauter are much more expensive, but you don't want to gamble with expensive lenses or bodies.
