    Re: 5x4 processing marks. Wetting agent?

    Thanks David. That sounds like a good idea. That should allow the wetting agent to reach the film evenly.

    Re: 5x4 processing marks. Wetting agent?

    Thanks Doremus.

    I think you may have spotted the problem/mistake, on my part.

    After the final wash, I was just adding a couple of drops of Photo Flo to the water in the Combi Plan tank, lifting...

    Re: 5x4 processing marks. Wetting agent?

    Thanks Ken. I use a Combi Plan tank. I loaded the sheets from a combination of sheets stored in an old film box and from the dark slides. There were marks on both. I think there were more marks on...

    Thanks John. I use Paterson film clips. There is only the point of the pin touching the film.

    It has happened on several sheets and always in the same place. I appears on the upper most corner when drying.

    5x4 processing marks. Wetting agent?

    Hi,

    I have an issue with processing marks on my Ilford FP4 5x4 sheet film. I appears to be like a greasy deposit on the emulsion side of the film. It does clean off, once the negative has dried,...

    Just to add. I bought the Fomapan 100 film in Half Plate and it fits the Fidelity holders perfectly.

    Thanks Andreios, that helps a lot. I can now order the film in the knowledge that it will fit my backs.

    Re: Fomapan 100 Half Plate size?

    Thanks for the quick reply.

    I trimmed some paper down to 6.5" x 4.75" and it does not fit the film holder. It does need to be 1mm smaller to fit in the slot. I am hoping that Foma make some...

    Fomapan 100 Half Plate size?

    Hi,

    I have some Fidelity Half Plate dark slides. They are labelled 6.5" x 4.75" - 12x16.5cm.

    I am looking at buying some film. Other than a special order for Ilford film, I can only find...

    Centre Filters - Schneider vs Rodendock

    I thought I would share this thread, in case someone is looking for a centre filter for a 90mm lens or is thinking that centre filters are all made equal!

    A while ago I purchased a Rodenstock...
  14. Re: Best center filter for Rodenstock Grandagon 90mm f4.5

    It may just be that these center filters are designed for use with 5x4 for these lenses. As I am shooting 5x7 and 6x17, I am using the edges of the image circle, where the addition of a center filter...
  15. Re: Best center filter for Rodenstock Grandagon 90mm f4.5

    Thanks. I will check out that auction site.

    My guess is that 3 stops may be just too much. I think 2 stops would be better. At the moment, I am also thinking that it may be a better idea to match...
  16. Best center filter for Rodenstock Grandagon 90mm f4.5

    Hi,

    I have a Rodenstock Grandagon 90mm f4.5 lens. I am using it to shoot 5x7 and 6x17. I tried it without a center filter but there was just too much light fall off. While this isn't an issue with...

    Schneider Angulon 210mm f6.8

    Hi,

    I'm looking for a Schneider Angulon 210mm f6.8 lens to go with a Canham JMC 10x8 camera. I already have a Fujinon 300 C lens and I'm looking for something a little wider. I was wondering if...

    You will have problems with continuous tone areas in CS4 too. The combined images will open in Photoshop as individual layers, so if one is too light or dark you can vary the brightness to some...

    Re: large format scanning and printing

    Hi Larry,

    Here is what I use and can highly recommend. To scan I use an Epson V750. This has a maximum negative size of 10x8 but it should be possible to scan a 11x14 negative in four sections and...

    Hi Pete,

    The only movement used was about 20 mm of rise on the front standard.

    If I try this again, I think i'll be a little more ambitious and maybe try it on 5x4 with a 90 mm lens. I'll put...

  27. Re: The power of Photoshop! 10x8 negatives stitched

    I see what you mean Vaughn. I'll try it soon. The pictures were taken with a Canham field camera and the Lens standard can't move far enough back. I've ordered a Canham metal field which might be...
  28. Re: The power of Photoshop! 10x8 negatives stitched

    I think they are a brilliant concept. I do own a Canon G10, so I may be tempted by a Gigapan day out if a friend will share the cost. I wonder how they would look printed out on a massive scale?

  30. Re: The power of Photoshop! 10x8 negatives stitched

    Hi Vaughn. I just rotated the camera on the tripod head, so this wouldn't have been around the lens axis. The first image is parallel to the beams. I still can't believe Photoshop sorted out all the...
  31. Re: The power of Photoshop! 10x8 negatives stitched

  32. Re: The power of Photoshop! 10x8 negatives stitched

    With hindsight, I think I could have achieved the same result with a 5x4 camera. The use of a 10x8 would only really be necessary if you wish to have a bill board size photograph!

    I think what this image illustrates is that Photoshop should be able to join any subject. I purposely chose this subject for its complexity and it worked a treat. It is essential that the camera is...

    Re: questions about metal 8x10 field cameras

    The two prints that I compared were 20x24. The difference may be less because I am scanning the negatives. The 10x8 scan needed no Unsharp Mask in Photoshop, where as the 5x4 needed a little. Two wet...

    Re: Nikkor 120mm f8 SW for 10x8?

    The Nikkor sounds like it will be a good investment for 10x8 film. Do you need a centre filter to ever out the light distribution across the film?
