Easy to develop
Great for portraits

UVP X is a premixed salted collodion used for tintypes, ambrotypes, and glass negatives. It is formulated with two iodide salts and two bromide salts. It’s a cadmium-based formula that ages slowly, so you will have consistent results over a long period of time. Stored in a cool dark place, this collodion will maintain good working properties for 6-12 months.

UVP X is specifically formulated with a slightly higher bromide ratio, which aids in achieving good tonal range in portraits. Also, it is easy to see the image during development, which helps achieve the most from the collodion. It’s the fastest of the super stable formulas (Lea Formula 3, UVP-4, UVP-X).

    Fast and stable

    Posted by Brent on Apr 5th 2021

    I love this collodion. I used a bottle for approximately 90 days last summer and saw only minor increase in exposure time. It’s one of the fastest collodion I’ve ever used. Thanks

    Great collodion

    Posted by Liz on Mar 29th 2021

    UVP X collodion is great! Super fast with great contrast, my new favorite formula. I was exclusively shooting OWH before and I'm getting much better exposure times now, though I notice my plates are scratching a little easier in the wash (but fine once dried).

    My favorite

    Posted by Laura on Jan 22nd 2021

    This stuff is actually great! I mixed my own chemistry for many years but I know prefer this blend. It is consistent and does not lose speed so quickly so I feel confident enough to buy larger bottles. I use it for studio portraiture work and even after 2-3 months I can still use 1- 2400 ws light with a modifier ( Beauty Dish or Softbox) and a reflector to get well lit photos. Often I will use 2-3 lights as well depending on what I am going for.

    UVP X (aka unicorn blood)

    Posted by Andy P on Jan 11th 2021

    UVP-X is some form of magic unicorn blood. I’ve split a 500ml bottle into 2 smaller bottles. One I kept out in my studio under the lab hood and used as a test bottle for 12 months. The other I kept in my chemical fridge for the same time and left sealed. After 12 months the X left in my studio showed only minor signs of speed loss and a noticeable amount of contrast gain. The refrigerated bottle shows no signs of death 16 months after delivery. Speed has gone down by MAYBE 1/3 of a stop. Amazing stuff and a great place to do business with
