burger tray light seals
Went to the local super market, bought some really nice beef burgers in a black plastic tray. Went home cut up plastic tray and made a copy of Hasselblad light seal. Found a suitable piece of foam strip cut to size, completed fitting new diy seal. Ate burgers, nice! 9 months on, light seal still nice and tight on dark slide, no light leaks.

I personally do not think the fogging here reached the film through the DS light trap! This effect is easily caused by "fumble fingers" when loading or unloading.
It would be much easier diagnose if you had posted the negative strips them selves.
I'll be interested to hear if you solve these leaks. It's that second picture you posted with the leak on the bottom right that interests me. I had something similar recently, happening in the exact same place consistently, but leaks also occurred towards the center of the bottom of the frame. I'll attach a sample of a close crop. Oddly, there was on a few frames a dark line too running along the bottom of the frame (you can barely see it in this attachment).
The first thing I did when I saw it was go outside and test the 4 backs I used. Shot rolls with the lens cap on in strong sun. Two displayed classic leaking when the slide was taken in and out in open sun. But I was not able to recreate the bleeding on the bottom of the frame. Huh, right? Anyway, I'm replacing foam on them to be sure.
Then shoot keeping track of rolls to backs. So if occurs again, to see if I can catch the bad back.
Anyway, let me know if you come up with any solution.
Sorry, for not replying to the questions earlier.
Charlie, is right when he said that the leaks could be from my fumbling when loading the film. The second and third test rolls from the back are perfect and show no signs at all of light leaking through. So far so good.
Since the new light seals I ordered have arrived I proceeded to have the seals changed. Anyway, I already sold this kit to a friend last week and informd him of the light leaks in mt first test roll, but the subsequent rolls are fine and I have already changed the light seal myself, just in case.
I sold the 500cm as I managed to get a relatively good deal on a like new 503cw set. The new kit has a minty 503cw body, wlf, 80mm cfe lens, 2 A12 back, 150mm CF lens. All come with boxes and manual. This 503cw set costs me about usd2300. The seller said he was the original owner (with receipt as proof) for about a year+ only and has shot about 20 rolls only.

Well, there you go. Loading a Hasselblad film magazine for the first time can be an, shall we say, interesting undertaking. There are lots of ways to screw up. After a couple of tries it gets to be automatic, like driving a standard shift car. I'm betting money that you had some difficulty.

Just pull enough to fit the tab into the take up spool.
What you also do not (!) want to do is flap the film about after locking the guide clip.
The guide clip is not meant to hold the film. Just to pull it down a bit, so it doesn't snag when you put the insert into the magazine.
So do not (!) follow that part of the instruction, but do it right instead:
- after sliding the leader underneath the guide clip, pull enough of the leader to fit the tab to the take up spool,
- turn the take up spool until the start mark appears opposite the triangle, pulling the film through as you go,
- turn the magazine's lock key to engage the guide clip, and drop the insert into the shell
and go on from there.
This guy does that part better (but note the "Oops! It's kinda loose."!).
But he doesn't have a clue about the function of the guide clip, and hence forgets to lock it down before putting the insert into the shell.

Want to know how to properly load a Hasselblad back? Go here. If you find it useful, send the guy the couple of bucks he asks for the service of having all these manuals on line and available 24x7. From the looks of it, half the folks putting these videos out there have not ever read the darned manual.
You can also find manuals here, and not be asked a couple of bucks.
Thanks for the pointers guys... I think it was beginner's error on my part. As I said before, the 2nd and 3rd rolls from the back were fine even before I installed the new seals. And so far I have taken more than 10 rolls with the same back without much problems. But thanks for the reminders on what to look out for. Appreciate it.
