  1. Re: Troubleshooting, or What the Hell Is That?

    Much better, Ari! Well done!
  2. Re: Troubleshooting, or What the Hell Is That?

    Ari, the issue with the streaking on Lund plate material seems to be intermittent (batches vary?) and dependent on the materials used, how they are used (development times) and whether or not the...
  3. Re: Troubleshooting, or What the Hell Is That?

    I will not buy the trophy plate from Lund anymore. It introduces too many problems with streaks like what you're experiencing. That's why I asked if you were using the plates with the white backing....
  4. Re: Troubleshooting, or What the Hell Is That?

    Ari, how long does it take for you to submerge the plate in the silver bath? More than one second? A 4x5 plate should be submerged in one second from start to finish, as long as you are not...
  5. Re: Troubleshooting, or What the Hell Is That?

    Yep, I am not surprised that the marks you were getting were 90% the result of pour technique of the developer. Aim to get the whole plate covered within the first second of the pour, and worry less...
  6. Re: Coverage for Turner-Reich 12/21/28 Convertible Lenses?

    My sense is that these will almost cover 11X14, and have plenty of room for movements on 8x10, but this is just my impression from casual observations. Sharp? My copy has plenty of sharpness when...
  7. Re: Wet plate process not producing an image

    Excellent work!
  8. Re: Wet plate process not producing an image

    There's nothing wrong with your collodion pour technique. Those swirly marks are contaminated silver from a previous plate making their way onto the surface of the plate and developing out. You'll...
  9. Re: Wet plate process not producing an image

    That's what I thought. Glad to see you're getting results now! Awesome.
  10. Re: Wet plate process not producing an image

    Bright sunlight at what f-stop? If you're using f16 or smaller, the exposure could be up to ten seconds, possibly more. I suspect your exposures are not long enough. I made a glass collodion negative...

    By the way, there IS an August wet plate image sharing thread available now.

    Re: Wet Plate image sharing, August 2020

    90% of the wet plate work I do these days is negatives, so I treat them much the same as I do with regular negatives: scan and make some adjustments in Lightroom to massage contrast, add some...

    Re: Wet Plate image sharing, August 2020

    Randy,
    I have a repurposed Styrofoam cooler I keep all my collodion in, and its outside in the laundry room/back shed. It doesn't get exposed to a lot of light, but it gets quite warm out there. On...

    Wet Plate image sharing, August 2020

    Its a new month. And this is the first plate I've done in weeks. Exposure was correct on the first try, much to my surprise.

    5X7 inch collodion negative (on glass), made with my moth-eaten Burke &...

    Re: Longest Wet Plate Exposure Times

    I think my longest was about 12 minutes. It CAN be done, if you know how to do it. Obviously you aren't going to be able to do this if the temperature is 95F.

    There is mention of this in some of...

    Ari,
    I don't believe your technical problems (as evidenced above) have anything to do with unwanted material in your silver bath, unless you are really, horribly sloppy with technique (which I...
  19. Re: Chroma Wet Plate Holders - Standard/custom sizes

    But what material are they made of?? If 3D printed, PLA should be avoided because it deforms too easily in warm conditions. I hope you're not using PLA.

  22. Re: How do I achieve this look? Lens or movement?

    Agreed. This is much more a lighting question and not so much about a particular lens. I believe that on 8x10 Polaroid you could use any one of at least a dozen lenses (aperture wide open) that would...

    OK, that's great! I'm glad you are using the right tools to make correct adjustments. Well done.
    You don't need to filter anymore. If the bath reads 1.074, then you are good to start making plates....

    Re: Cloudy silver bath, is it usable?

    Yes, the cloudiness is almost certainly the result of too little AgNO3 in the bath to reach equilibrium.

    Re: Cloudy silver bath, is it usable?

    Ethan,
    When you added more AgNO3, did you measure the specific gravity of the bath to get it adjusted to the correct SG? Do you have a hydrometer to make these measurements? Did you measure the SG...

    If you have Coffer's manual, its in there: page 40 has the base formula, and page 42 has the warm weather modification notes. Publishing the recipes here may be a violation of JC's copyright.

    Maybe I've just been lucky, but I have not had issues like this with my Petzval lenses. WYSIWYG is how they've worked for me.

    Yes, they do so intermittently.
