    Re: Dichromate bleaching and redevelopment

    I wonder if perhaps I'm leaving the print in the bleach too long... I only have it in there a minute or so, but it really seems to bleach out fast.

    Re: Dichromate bleaching and redevelopment

    Thanks, Michael. I'll try it again when I have fresh developer made up.

    Dichromate bleaching and redevelopment

    So... I read in Tim Rudman's Master Printing Course (page 74) about bleaching prints and redeveloping as a method of intensification. I thought I give it a try, especially since it said something...

    Nope.

    I frame my 16x20s in a 28"x32" frame and would have no problem going bigger. It depends on how it will look in the wall space you plan on hanging it. White space around a picture always enhances...

    Re: Resin Versus Fiber Base

    I print only 8x10s and 16x20s. I always do 8x10s first to get a feel for what contrast filter to use and what manipulations are required. They are always RC prints.

    All my 16x20s are fiber and...

    Re: Sheet film handling

    Good question. Back when I was doing transparency film, I would just take a stack of film holders down to the lab and pick up the empty holders and processed film four hours later. Them were the...

    Re: Uneven 4x5 development w/old Jobo tank

    Here is a scan of one of the problem negatives. The "fogging" is on the right side and clearly lines up with the features of the reels.

    Re: Uneven 4x5 development w/old Jobo tank

    I'm using the 2336 tank with 2021 reels, so there are no plastic wedges. The wedges were for the 2509 reels.

    Also, I'm using a unicolor base which does switch directions, but I don't know how...

    Re: Uneven 4x5 development w/old Jobo tank

    Yeah, I just can't find a light leak, so it would seem like it HAS to be a kind of fogging. But, it sure looks like a light leak. There is actually dark streaks on the unexposed part of the film...

    Re: Uneven 4x5 development w/old Jobo tank

    I will check out HC-110. My experience with Xtol is limited to my current testing of several different developers (including Pyros). I haven't settled on anything yet, but hope to soon. I don't...

    Re: Uneven 4x5 development w/old Jobo tank

    I'd rather not have to go that route since I like to do one-shot developer which means I'd be throwing a 1.5 liters away every time I develop film.

    Also, the most film I've had in the tank at once...

    Do you mean you are using the 2509 reels with the 2336 tank? I can get the newer reels on ebay, so that might be an interesting option.

    Well, now I feel guilty for starting a thread and THEN finding so many related threads on the topic.

    From what I gather, the newer 2509N reels have pieces that secure the ends of the sheets in...

    Hmmm... Guess I should have done a better search before posting a separate thread about my problem with uneven development using this very tank and reel...

    Uneven 4x5 development w/old Jobo tank

    I just started processing 4x5 B&W in an old Jobo tank that uses 2021 reels. These actually predate the 2509N reels that seem so common on ebay, but they are similar. They take 3 shhets on each side...

    I started the thread. It's about the effects of refridgerating chemicals. It's not about how to be a better parent. Your comment was not a subtle suggestion or a comment. It was preaching as if...

    And I suppose you're next going to tell us that we shouldn't let our kids play with those plastic bags that come from the dry cleaners... ;-)

    Thanks for the info. I'm not a big fan of mixing my own chemicals, but I will read your article on digitaltruth.

    Re: Pyrocat HD vs MC

    OK, thanks to all for the comments. I decided to place an order for the MC in glycol so I can compare it to the HD. I can understand someone wanting to stick with a developer they're familiar and...
  20. Re: Refridgerating chemicals: Does it make them last longer?

    Good idea. You know, I've often wondered about letting the water I use for developers stand for a while before mixing it. I use filtered water, but I suspect it has a lot of tiny air bubbles it it...
  21. Re: Refridgerating chemicals: Does it make them last longer?

    I like the marble idea, even for plastic bottles. I noticed B&H only has the gallon size air-evac bottles in stock these days. You have to go elsewhere for the 1/2 gal and quart size.

  22. Re: Refridgerating chemicals: Does it make them last longer?

    I could try something smaller. It's just that I plan to mix up five 1-liter bottles of the stock.

    How long would it take for the crystals to form? Is it something that might take an extended...

    Pyrocat HD vs MC

    I've decided to give Pyrocat a try. I noticed the two versions on Photographer's Formulary, but am not clear about the benefit of each.

    From what I gather after looking around on here, MC is an...
  24. Re: Refridgerating chemicals: Does it make them last longer?

    I'm talking about having to mix 5 liters of Xtol stock at a time and using it kinda slowly (I'm not a prolific shooter). The data sheet on xtol is a little ambiguous about shelf life, apparently...
  25. Re: Refridgerating chemicals: Does it make them last longer?

    I have a dedicated refer for film. It has a lot of extra space for chemicals, though.
  26. Re: Refridgerating chemicals: Does it make them last longer?

    Uh-oh... From what I've read, Xtol is a phenidone/ascorbic acid developer. Guess I could put a liter of it in the refer and see if anything precipitates out. It would be visible, wouldn't it?
