    Hi,

    I've just spotted reference to the 'taco' method for developing sheet film on 'another thread'. I've seen this mentioned quite a few times in passing on APUG, but haven't found a clear explanation as to what it is.

    I think I know what a taco is - but I'm not sure how folding a film in half, stuffing it with mince, cheese and chillies and bunging it in the oven will help.

    Can anyone explain this one to me?

    Thanks.

    "Taco deevelopment" is merely gently folding a sheet of cut film, so as not to crease it, putting a rubber band on to hold the shape then placing in a daylight tank meant for two or more reels of film for processing. This allows developing up to four sheets at a time. The shape of the cut film resembles a taco inside the tank. This can be done in a plastic two reel tank, but will not work in a stainless steel tank as it isn't tall enough.

    Rick is right, and I remember there was a Jobo insert for sheet films and papers that could hold five or six sheets rolled like that in a large rotary tube.

    But there is another alternative:

    5 onions
    2 bell peppers
    5 Piri Piri fruit
    12 small tomatoes
    1 cup jalapeno peppers
    1 cup sugar
    1 cup vinegar
    1 cup vegetable oil
    1 cup water
    4 tablespoons salt
    4 tablespoons black pepper

    Chop all ingredients and simmer for 3 hours. Use a blender to make a nice sauce.

    Put a lot of this sauce on a taco and enjoy the meal.

    I 'm sure with this taco you will develop a heartburn. :wink:

    I did a blog post a little while back about how I do the taco method. It uses a lot of chemistry but I'm happy with the results.

    Now I need to make some taco sauce :smile:

    Thanks for the replies guys,

    But please tell me, what is a piri piri fruit?

    Can I get one of these from my local photochemical supllier? :-o

    Mince for the shadows, cheese and chillies for the highlites. Oven bunging(?) ensures complete development. Not sure about the piri piri, but I'm guessing some sort of catalyst.

    No problem. Never let it be said that I hadn't done the least I could.

    Or, use a Kodak taco tank. Here is the insert:

    Piri piri is a small, extremely spicy sort of chili peppers. They have up to 175,000 SHU (Scoville heat units) - normal Jalapeno has 2,500-8,000 only.

    For 'push development' use Naga Viper pepper, stock solution, it has almost 1.4 million :whistling: I think you don't get this from a photochemical supplier, ask an arms dealer.

    One of the advantages of this method is that the films will agitate themselves while trying desparately to escape from the tank.

    I thought these only existed in legends and eBay auctions.
