The Helga is a rather rudimentary camera. My question: If the labor of 
developing and printing is the same for negatives produced by a better camera 
of the same film format, why not spend a few bucks for the better camera, 
albeit a good used one. More will come on the market at even less cost as the 
public becomes victim of the digital craze.

Shannon  The first word that caught my eye was the word Holga.  First thing I 
would check is the negative itself to see if the ring is on the negative as 
well.  If you are unsure, the next step would be to try and contact print the 
negative and see if they rings appear there.  A contact print eliminates almost 
all if not all the other variables you were concerned about.  Are they still 
there?

Holgas are famous for things like light leaks, lens flare, and I think I 
remember something about internal flocking problems but that may be the Kiev's. 
 Before you question your technique too much, Id rule out the camera as the 
problem first.

The other word that caught my eye was Doughnuts.  Hmmmm $1 to Homer Simpson.  
Personally I am partical to Krispy Kremes.

Yet another weird mystery in the darkroom....

Today I noticed that there are these light-colored donuts right in 
the center of the prints I was making yesterday. They are Holga 
panoramas, so I was printing a five inch strip of 120 film by laying 
it on the glass negative carrier that's for 8x10 negatives. It has 
frosted glass, I guess to prevent newton rings or something. But now 
there are these other kinds of rings!

I was using the 135mm enlarging lens, which appeared to cover the 
negative fine. I had it stopped way down to f/32 though, because the 
head had to be so close to the print to make it only 12" long.

The head is a diffusion head.

Is it possible that this frosted glass is creating this problem? I 
have used it before and never noticed it before.

Another clue: I cleaned the frosted glass with Windex before 
printing. I think I got it all dry. But it's possible it was 
slightly dampish when I was printing. I printed three negative 
strips, and all three sets of prints have this strange anomaly on 
them.

You can see the phenomenon here:

My partner said I should just say it was a picture of nuclear winter 
in Houston.
