How did you determine exposure time? there was no flash. iso is 2 to 3 i suppose. .most books talk about 25 to 60 seconds. Im stymied when it comes to exposure.
@quinnjacobson 9 сағат бұрын
Exposure is based on light (type and strength), optics (aperture), and the age of your collodion. I've covered all of this extensively in Chemical Pictures.

In reference to the Becker quote I mentioned about Stephen's painting called "In the Teeth of Time." Timestamp: 59:24 "What are we to make of a creation in which the routine activity is for organisms to be tearing others apart with teeth of all types-biting, grinding flesh, plant stalks, bones between molars, pushing the pulp greedily down the gullet with delight, incorporating its essence into one's own organization, and then excreting with foul stench and gasses the residue. Everyone reaching out to incorporate others who are edible to him. The mosquitoes bloating themselves on blood, the maggots, the killerbees attacking with a fury and demonism, sharks continuing to tear and swallow while their own innards are being torn out-not to mention the daily dismemberment and slaughter in "natural" accidents of all types: the earthquake buries alive 70 thousand bodies in Peru, automobiles make a pyramid heap of over 50 thousand a year in the U.S. alone, a tidal wave washes over a quarter of a million in the Indian Ocean. Creation is a nightmare spectacular taking place on a planet that has been soaked for hundreds of millions of years in the blood of all its creatures. The soberest conclusion that we could make about what has actually been taking place on the planet for about three billion years is that it is being turned into a vast pit of fertilizer." Ernest Becker The Denial of Death

These are really great inspiring videos, I have the ebook and Ive made a few tintypes but the lack of a proper darkroom is inhibiting the process. Walking from the bathroom/darkroom the sensitized plate invariably drips on the floor and the silver stains are impossible to remove. Tips? Also Im thinking that a portable darkroom may be the way to go, so how small an enclosure can you get away with? Many thanks 🙏

Thank you for the kind words. Silver stains: KCN will remove them. Yes, I use a portable dark-box - they can be quite small as long as your plates aren't too big. I make Whole Plate images in mine, plenty of room. If you search my channel, I'm sure you can find it. You can also use an Eskimo tent or a film tent - I think Ilford makes one.

Hi Vanessa, don't worry, nothing bad will happen to pour back into the "pouring bottle". If you use a separate "drain bottle" you maintain the solvents in the "poor bottle". Also, if you're outside, and you get debris on the plate (fly, dust, etc.) you can easily remove that from the "drain bottle". You will lose solvents (evaporation) and you can reconstitute that drain bottle so it's like new.

Hi Quinn, thnx for your videos and the book. After months of reading and preparing I’m almost ready to start with my first plate. One thing I’m not sure about: after preparing the silver bath with a glass plate with collodion, the bath is ready. Does that mean it’s light sensitive? Do I need to store it in an amber coloured bottle and only work with it in safelight, or am I overthinking it and can I store it in a clear glass bottle and fill my silver tank in daylight?
@quinnjacobson 2 жыл бұрын
Hello, Monique, thank you for your support (buying my book). Congratulations! You're going to really enjoy it! No, the silver bath is fine stored in clear glass or good plastic. No need for amber or dark bottles. It's only sensitive to light if there is some kind of organic material in it. I would recommend storing it in a cooler, or your darkroom. But you can work with it in light, no problem, and store it in a clear bottle. I store mine in clear glass bottles.

Hello, Vanessa, the pH plays a role in how much silver is decomposed on the plate (double decomposition). The more acidic, the less silver, the more basic, more silver.

Dear Quinn, No idea if you would read this since this is such an old video. But I seem to have a particular problem with dirt and dust in my tank. I filter my silver before and after every session, I've sunned and did maintenance so the silver is perfectly fine. But everytime that I begin a new session I pour the silver nitrate in to my tank, and my first plate looks horrible. If I then filter the silver again out of the tank and back into the bottle => and then pour back into the tank : problem solved, everythings clean and works like a charm. Now I've been trying to solve this issue but can't find a solution. Is it dirt and dust that sets in the silver nitrate tank? I've tried cleaning it with distilled water and before a session, didn't help. I've tried using paper towels to dry it after cleaning and I've tried not drying it with paper towels -- but the same problem keeps on happenening. (and the solution is always the same: filter back out of the tank and pour back into the tank). Any idea how to find the source of this issue and how to resolve it? Many thanks and thanks again for your literature and videos! Cheers, Wouter

I am using a poeboy collodion (Cadmium bromide is not available in South Korea ) The picture is still blurry or the contrast is poor. I'm not sure if it's a silver nitrate issue or a developer issue. Collodion was definitely well made. The developer made it well by adding iron sulfate, acetic acid and ethanol. But the picture is blurry. I am doing an ambro type. Is it a problem with silver nitrate? Specific gravity is exactly 1.07. If the pH of silver nitrate is about 5~6, can the picture be blurry or the contrast is weak?

After watching this particular show I thought it would be fun to make some Collodio- Chloride prints so I made up some emulsion yesterday and left it to rest overnight. This morning I noticed that the emulsion was obviously more opaque at the bottom third of the amber bottle. There doesn't seem to be any cotton precipitate just somewhat thicker liquid. I gently did a few roll and turn motions, like a slower version of processing with a daylight tank, and the emulsion seems more evenly distributed. Is this a normal thing or has something gone wrong? I left the emulsion spinning on my stirrer for 5 minutes after the last of the AgNO3 was introduced.
