    p.s. In case anyone has missed it, emulsion101 is more than Ian's website, it is a silver gelatin emulsion forum he established.
    Hi Denise,

    Yes, I have chosen to forgo chasing an income for a bit, instead concentrating upon converting my earnings into silver halides ( a remarkably quick process!)
    Cooked up some bromide last weekend, hoping to sulfur it and coat film this weekend.

    I hope some of the people who have participated in this forum over the years will decide to jump in and learn a Craft that almost literally has no creative boundaries.

    Happy Holidays to All,

    Thank you. I will definitely tune in. And Happy Holy Days to you, too!

    Looking forward to this! Will be a help to a lot of people. Are you going to cover Silver Gelatin Paper or just plates?

    Hi hermit,

    Glad you're interested! I recognize you as a collodion guy. I hope you find dry plate enough easier, safer, and more flexible that you'll join the gelatin crew. Beauty, of course, is in the eye of the beholder, and as beautiful as a number of processes are, I don't think anything compares to silver in gelatin.

    The tutorials will cover papers and negatives (both dry plate and film). I have imagined that silver gelatin is as much a part of the public school system as reading, writing, and arithmetic. We've all been through pre-school and kindergarten where we've looked at pictures and are aware of the general breadth of the subject.

    The tutorials start in "1st grade" and will spiral up and through increasingly complex recipes and techniques. I'm going to try to hit a speed that everyone participating real time will have plenty of time to keep up. We'll see how all this goes as it gets more complex. I have high hopes it's going to be great. In a year or so, when everyone "graduates high school", and I know better how to do this thing from the web, I hope we can go on to bi-packs, tri-packs, near-pano film, and an autochrome-type film. Fingers crossed and face forward into the wind!

    Panchromatic emulsion?

    Denise,

    In your most recent posting on your silver gelatin tutorial, you mention "near-pano film, and an autochrome-type film." By this, I assume that you mean some sort of panchromatic emulsion? PhotoEngineer (if you are reading this), will you deal with panchromatic emulsions in your March workshop at the GEH?

    Thanks,
    Charlie Palmer

    Charles;

    Making a red sensitive emulsion and then blending with a green emulsion and a blue emulsion is a good way to do it. Make a blue under amber or red safelight. Make a green under red safelight. Make a red under green safelight. Then you blend all 3 1:1:1.

    BUT, with a panchromatic sensitizer and one emulsion, you essentially have to use IR goggles to do any useful work. This is pretty tough and can be expensive. BTDT.

    In the GEH course, we may discuss it, (and the above is part of that) but we do not intend, at this time, to go further than discussion and perhaps an ortho emulsion. Besides, pan dyes are not easy to get and are very very expensive.

    BTW, his is not covered in the book. It is a possible topic for V2 of that type of work. Hermit above may find my book interesting if he is interested in silver gelatin. I am interested to know if there should be a V2.

    Charles,

    Yes to near-panchromatic. "Pano" was a typo (Actually, a brain hiccup. For the longest time when I was a teenager learning photography, I thought it was panochromatic film. That still slips out, just like my Minnesota accent, at the oddest times -- and I haven't lived in Minnesota since about the time I was learning photography. )

    As Ron says, the chemistry for (true) pan film is expensive. And IR goggles are just a bridge too far for this girl. In truth, I don't personally see the need for true panchromatic film. Ilford and others make the stuff brilliantly. I want to build materials that can't be bought, and the ones that catch my fancy (like tri-packs and autochrome, and heaven help me, 16mm movie film) can be approximated with near-pan film. I have the basic recipe almost to where I want it. Still has a higher base fog than I like, and reversal is hit-and-miss. That recipe and its children will be at the front of my research schedule this coming year, sharing time with the tutorials.

    A question about the photographic gelatin. I searched for that on Photographer's Formulary but couldn't find it. Is this what we need to buy?

    http://stores.photoformulary.com/-st...%29/Detail.bok

    Also how much of the potassium chloride and photographic gelatin should we buy?
    Thanks,
