  1. Re: Please help me identify the source of this light leak on my negatives.

    My basement is the only place in my house I can black out. But i isn't light leak free until night with all lights on the floor above turned off. It's definitely not dark enough for film during the...
  2. Re: Please help me identify the source of this light leak on my negatives.

    So I was wrong about everything. It was the Paterson dark bag. Turns out it actually isn't that dark. Was pretty apparent when I stuck my head in it near the light where I work. This would explain...
  3. Re: Please help me identify the source of this light leak on my negatives.

    Probably not. I'm not sure if radon gas would cause film to fog, but I got my basement tested for that and it would have effected roll film in my changing bag if it even could be a cause. I would...
  4. Re: Fujinon EX 135mm enlarging lens not fitting 53mm lens board.

    I ended up getting the lens board with retaining ring from Custom Photo Tools and its great! Looking at my order confirmation I got the following: "Lensboard 4 x 4" for Beseler enlargers 53mm - with...
  5. Re: Please help me identify the source of this light leak on my negatives.

    I think I found the issue! TL;DR I think its stray light when loading the film holders.

    I went out to shoot yesterday morning with film holders loaded up with HP5+ and FP4+. For each scene I took...
  6. Re: Please help me identify the source of this light leak on my negatives.

    When I take the fresh film out of the box, I keep in in that cardboard folder its in. The notch side of the film and the adjacent boarders would be a bit more exposed I suppose. When loading the film...
  7. Re: Please help me identify the source of this light leak on my negatives.

    Okay everyone, I did some more testing and it has just left me with more questions than answers. Without going into all the details I think I can rule out bad film holders as the issue. I also think...
  8. Re: Please help me identify the source of this light leak on my negatives.

    I suppose you are right about the nature of the sheet with the deliberate light leak. I wonder if I pulled the film holder away from the other edge if it would look closer to the results I am...
  9. Re: Please help me identify the source of this light leak on my negatives.

    1) Film is loaded in my blacked out basement, at night, with all lights and light sources off in the basement and the floor above. It is the darkest place I have ever been. My test of developing the...
  10. Re: Please help me identify the source of this light leak on my negatives.

    I've checked the bellows using a bright light source in a dark room. I've also refitted them to the camera and everything seems fine. I would not think a light leak from the bellows would fog the...
  11. Re: Please help me identify the source of this light leak on my negatives.

    I thought that too regarding the box of film. However, this issue has survived through two boxes of HP5+ and occurred once again after running these tests. The film I am using should be fine.
  12. Please help me identify the source of this light leak on my negatives.

    Problem: Most of my hp5 4x5 negatives are fogged. The side of the film with the notch codes will be darker than the other side and it forms a bit of a gradient. The fog is present in the film rebate...
  13. Re: Opinion: Would a 90mm f8 or f6.8 lens be too dark for dawn and dusk landscape?

    Prefocusing the day before is not really an option for me with how I plan my trips (short couple hour trips for now). Shining a light on my subject at night sounds pretty amusing but may actually...
  14. Opinion: Would a 90mm f8 or f6.8 lens be too dark for dawn and dusk landscape?

    I'm starting to move over to large format to medium format landscape photography. I almost exclusively shoot black and white with the end goal of producing a silver gelatin print (up to 16x20"). My...

    Re: Unique/ lesser known portrait lenses

    I definitely agree on getting a lens with a working shutter and I'm not interested in barrel lenses. I guess I don't want much fuss.

    I was eyeballing some of the Kodak Ektar lenses like the 10"...

    Unique/ lesser known portrait lenses

    Occasionally deviating from landscape photography I like to try portraits when the opportunity presents itself. I'm pretty new to 4x5 and I currently am running a budget setup of a Calumet cc400...

    RA-4/color darkroom printing in 2021

    I'm going to try to ask this question without sounding like I'm trying to start an argument. Its something I've been curious about for a while but I couldn't find an answer to without making a post. ...
  18. Re: Fujinon EX 135mm enlarging lens not fitting 53mm lens board.

    Thanks for the caution. If this is the route I'm taking I'll be sure to wear eye protection and go slowly.
  19. Re: Fujinon EX 135mm enlarging lens not fitting 53mm lens board.

    Do you think a Dremel with a sanding attachment might work? I've been meaning to get a Dremel like tool for a while. Not sure if the sanding bit will work on metal.
  20. Fujinon EX 135mm enlarging lens not fitting 53mm lens board.

    Hi,

    This is my first post to this forum so I hope I am putting this in the right place.

    I am working on expanding my darkroom to accommodate 4x5 enlargements. I purchased a Fujinon ex 135mm...
