    Liquid Light Emulsion on Acetate film

    Has anyone attempted this, and if successful, what subbing did they use? Does the emulsion adhere well (logically it should since it is the base of most films?), or am I wasting my time!

    Thanks for any advice/help.

    Rgds, Kal

    Kal;

    The transparent support used for all photo films has an inert subbing on it to prevent the emulsion from being repelled from the support, and at the same time not discolor from photo chemicals.

    Plain acetate will repel the emulsion and it will slide off the support but for example, Inkjet film will allow adhesion but causes a high orange dmin due to absorption of chemistry during process.

    The only source of proper support I know of is the Photographers Formulary, an APUG sponsor.

    Thanks PE. What type of support am I looking for at the Photographers Formulary? The idea is to cut this in to 4x5 sheets and put the emulsion on. I assume I would not have to sub this support? Or will I steel need some form of subbing. Thanks for your help. I will go and have a look at their web site. K

    Kal;

    The Formulary has it listed on their front page, last I looked. It is custom cut and subbed on one side only, which is the "good" side. Have it cut oversize so you can trim it to fit the proper holder.

    Hi PE..just found it! This is great!...I had no idea you ran workshops. Cool. By the way, is it possible to "pour"the emulsion on to this base, or does it have to be brushed on? My preference was for pouring if possible. Anyway. Off to buy some ;-))K

    Well, pouring onto acetate is probably not going to work. IDK, never tried it. The pour method is used for plates though and works well. Brushing works but leaves brush marks.

    Spraying works well if you have the viscosity adjusted correctly. I use a coating blade just like I did at Kodak.

    I had thought of putting the acetate on a glass plate and doing the pour? Let it cool and then allow it to dry vertically. Anyway, worth the experiment. The PF send the base in 50inch wide and foot lengths. So I ordered 2 ft worth so about 60 4x5 sheets worth. I was trying to get the SE-1 emulsion sent from Silverprint, but they don't post chemicals overseas

    Anyway, made me think about the best way to make my own emulsion. What do you recommend for somthing like this base...also would appreciate an idea of what EI's you get. I believe SE-1 is supposed to be ISO1 or something!

    Use the one here on APUG. It is AJ-12, I think. It is a Kodak formula and gives an ISO 3 - 6 emulsion.

    Hi Kal,

    It's always great to see someone else getting interested in emulsion making. Welcome to the club!

    I publish a website about emulsion making. thelightfarm.com. I just this morning posted a new section on coating Melenex. Timing is everything

    http://www.thelightfarm.com/Map/Film...s/MapTopic.htm

    In addition to the Melenex article, most aspects of handcrafted emulsion making are covered. The body of knowledge is steadily growing. Check back now and again.

    I hope you find information you can use. Good luck!

    Thanks for the link Denise, I put it in my favourites for reference!

    PE, Have I understood correctly that I can buy the A-12 from the APUG site? I looked and could not find where.

    Let me know, since if I can buy from APUG, I would much rather do that and contribue to the site
