Profound joy and disappointment in new FED: leak?

A crease will cause exposure mechanically, mechanical energy "exposing" the silver compound instead of light energy. The effect you see can only occur if the crease occurs before development. Once past the development portion of the processing cycle, a crease will be only a crease with no image darkening.

No, they are actual black and white and gray this time. Best scans I've gotten from Walgreens. Usually they have an odd cast, I suppose from well-used C-41 chemicals on the negs.

Keep in mind that the drugstore treats BW400CN as color film, including scanning. I would always convert those scans to true b&w (grayscale) although in this case, and on my monitor, the pinkish cast looks pretty good in some of the shots.
 
Thanks, battery. I am mildly red-green color blind, so maybe I cannot see a pinkish cast. Another board member thought it had a greenish cast. I'll take a look at conversion possibilities, since I have a brand-new laptop with 17.5-inch wonderful screen ...
 
I see. Well, the pinkish cast is very slight in this case. It's the same hue as in those mechanical defects (hole in boat negative #1, crease in shovel negative).

What I was trying to say is that a cast in drugstore scans (or prints, for that matter) from C-41 B&W does not mean that their developing chemistry is off. I scan my rolls of BW400CN at home and usually let the scanner run on full auto for a quick assessment first. This gives all kinds of different color casts on the same roll. Then I do real scans on the keepers, and the jury is still out as to scan straight to B&W, or scan as color and then convert to gray.
 
i've encountered all of the problems shown in the photos. another problem is the cloth shutter's opacity, which will degrade in time. luckily, a very skilled technician can fix all of these issues. these cameras are quite old, and that's the reason for the malfunctions.
 
Just in the few days I had the body, I kind of fell in love with it. The long-base rangefinder is a HUGE help in focusing. I can't figure how that crease got into the shovel frame, which was at the end of the roll, if the lab did not do it. Perhaps I did not have the spool loaded correctly ...
 
Paulfish,

It's normal for the curtain overlap to increase through the wind but there should be enough overlap at the start to give no light-leak. That suggests the curtains have been replaced and were not quite positioned correctly.
 
Paul, those were nice pics you took unfortunately marred by the shutter/leak problem. But I'm quite sure Yuri will get it sorted out. All the best!

The lab could still have done it. Its just that they would have to had damaged the roll while preparing it to load into the process or in loading it into the processor.

Its possible to fold over a portion of the film, causing marks like this, but usually double lines heavier toward the sprockets and aligned with the sprocket hole edges, by reverse winding the roll while attempting to retrieve the leader. This crease doesn't show the tell tale characteristics of this type of damage, but still could have been lab damage.
 
These Feds tend to show problems at 60. Mine did, & I believe I read the same on Jays website. I don't see the sticky shutter problem from any of your photos but they do look like a light leak & perhaps a possible hole in the curtain. Glad to read that it's gonna get a fix from Yuri. One good way to test the travel & speed of the curtains is to take both the lens & back off & hold in front of a TV. You can tell quite fast if the curtains are moving like their suppose to. Looks like you took some nice shots Paul.
cheers
