Disastrous Consequences (solved: fog with Intrepid lensboard)
So, I'm new to LF and I just got my Intrepid 4x5 and an assortment of lenses including my main lens - Nikon 90mm. Went backpacking. Processed the film and found that everything shot with that lens came out horribly wrong. I guess it needs to be serviced or replaced. Ever seen anything like this? I made a couple exposures with my Rodenstock 150 and that came out beautifully. Any idea what could be wrong?

Re: Disasterous Consequences
EIther your Nikon 90 mm is not a wide angle lens,or you are missing an element. I suspect it is not a WA. Does the ID on the lens indicat WA?
Re: Disasterous Consequences
What is your lensboard made out of?

No, not really. Sorry.
OTOH, you got your first lesson in LF -- the ground glass does not lie. It took me a lot longer than my first trip to fully, viscerally, understand that. Once I latched hold of that concept I wasted a whole lot less film, and my "winners" became a much higher percentage of my shots.
You done good. Stuff like this is how we learn.
Re: Disasterous Consequences
Which filter did you put on it? I ask because there's not too bad image in the corners.
A picture of the lens on its board would be helpful. Side views, so we can read the ID etc. on the front of the barrel.
Re: Disasterous Consequences
Did it look like that on the ground glass?
Re: Disasterous Consequences
They look just like pictures taken with my Holga!

If it’s not the lens it does look like some light leak... almost like the lens board is not totally light proof...?
Re: Disasterous Consequences
Put the lens on the camera, shutter closed, point it at a bright light, remove the camera back and see where the light leak is. It appears to be all around the lens, with the rear element blocking the circle in the middle from getting fully exposed to the light leak. Perhaps you re-purposed a lens board that had holes drilled for mounting a flange with screws?

Re: Disasterous Consequences
Here are a couple pics. Could this not actually be a wide angle lens? Could it have simply been that the lens was loose on the lens board? I sure appreciate your response. Attachment 208376Attachment 208377Attachment 208380
Re: Disasterous Consequences
On the various pictures that came out with the same defects I used a couple different filters. Orange and a polarizer separately.
