    777

    I read that 777 developer do smooth the edges of silver clusters. Is this a special case or do D76 , HC110 , D23 do this ?

    Typically the more sulfite solvent action, the less sharp the edges of the silver grains are. It depends on quite a few variables, including developer activity, sulfite content etc. D76 and D23 are of this type of developer (solvent developer). D76 is more active than D23 so the solvent effect is not quite as great. HC110 is a solvent developer but a little different. The dilution can have a significant effect though. If you dilute D76 or D23 you get less solvent effect.

    Regarding 777, well, it is a special case only in the sense nobody is 100% sure what the formula is, and, at least partially because of that, some people believe it to have magical powers.

    You order it from Bluegrass in Kentucky. No online ordering.

    I think there's a sort of waiting list at this time. They're probably waiting to get enough orders to mix fresh.

    A few things you should know about this developer.

    1. It is used as a deep tank replenished developer.
    2. It is expensive and the minumum size makes several gallons.
    3. It contains paraphenylenediamine which is toxic and a known carcinogen. At the very least this chemical can cause severe dermatitis and is a cross-sensitizer.
    4. AFAIK, there is no known MSDS for it and so you are operating blind as to its health risks.
    5. You may have truble getting it shipped internationally.

    You may ask why without a MSDS people know it contains PPD. The give away is the very distinctive smell of the developer.

    I would ask how they are allowed to sell it without an MSDS. It wouldn't be allowed here.

    Isn't PPD mostly dangerous in powder form? Is it dangerous in liquid form also? From what I understand it's also used in hair dye.

    When you buy the kits From Bluegrass, it comes in powder form, so you must use extreme caution and care when you mix it, so that NO dust of PPD is inhaled.

    My quest for info about 777 led me to a tiny little book by Morris Germain and his formula for Germain Finegrain, which had 7g Metol,7g PPD,70g Sodium Sulfite and 7g of Glycin.. It's been my first choice for all films for about six years now.
