The Studio Q Show LIVE! Chemical Pictures Wet Plate Collodion

[@robertallnutt3717]

Thank you for sharing your knowledge and giving us the opportunity to learn about collodion photography. I ordered your book

[@quinnjacobson]

Thank you! Send me an email and I'll get you a link to the Vimeo Workshop Video Series. wetplate at gmail dot com

[@AMENDEZE]

Super great!! Thanks!!

[@ShaneB666]

I just ordered your book then this pops up in my feed, the power of the internet.....

[@quinnjacobson]

Many thanks!!

[@hellofoto]

Wow! What a wonderful teacher, and a kind gentleman. Thank you very much for sharing your knowledge!

[@quinnjacobson]

Thank you. I appreciate your kind words.

[@blazerbarrel2]

Thanks ! Just starting this process. I do 20x24 silver negs and want to get to making wet plate positives. I read your book over and over and will start with 8x10 and use trays for the baths.

[@quinnjacobson]

Thank you for the support!

[@RogerHyam]

Thanks for this. I learn something every time!

[@quinnjacobson]

Roger, thank you for your support! I appreciate hearing there's value in these.

Saw this by replay, good stuff as always. My main quality issue is limiting my variables, especially outdoor light under trees (no studio). Now to move my commercially bottled collision into a clear bottle to better judge its color. Ciao

[@quinnjacobson]

Thanks, Don! Outdoor light is difficult because you are constantly "chasing the light:". In a matter of a few minutes (pouring the plate, sensitizing, etc. cloud cover, time of year, etc.). Once you nail it, there's nothing better! Thank you for your support!

I'm tripping. I have not been using a pour off bottle for my collodion. How bad is this? I mix smaller batches but I don't know if that would make any difference. What type of issues might I see by pouring my pour off back into my pour bottle. Now I'm scared I have ruined all my mixed collodion. 😔

[@quinnjacobson]

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, From your perfekt tutorials I understood, that one intend to overexpose - and actually my exposuretime in this German wintertime tend to 40-50 sec (with studiolights - UV lamps included). Could you talk a little about your setup - especially about the light - so that 5 - 10 sec are realistic? Thank you very much - and please go ahead. Your tutorials are so helpful!!! Cheers Bernd

[@davidcarpenter542]

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]

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.

Love that rotating doorway. For us in the UK does any body know what denatured alcohol is? Is it something like mentholated spirits, I asked in the chemist and they had never heard of denatured alcohol.

[@quinnjacobson]

Darkroom doors are the best! Yes, denatured alcohol contains additives to prevent consumption. Methylated Spirits (MEK) are/is denatured.

[@argentum_on_glass]

hi Jacob, always again I'm unsure what alcohol i should use as most of them are denaturated...will this work ? Ethyl Alcohol (ETHANOL) 96% 2 bottles of 250 ml each Do not drink, Only for external uses. Composition: ethyl alcohol 96% v/v Partially denatured with cetrimide of 0.25 to 0.3% m/V.

[@quinnjacobson]

This is denatured. I would be hesitant to use that but it will probably work. It contains cetrimide, an antiseptic. And it is 1% stronger than I recommend - 95% should be the volume of ethanol and 5% water - no additives. Try a small batch and see if it works. It probably will.

[@argentum_on_glass]

@@quinnjacobson the one i use at the moment is also a 96% one but i only got 1 Liter and looking for a bigger tank like 5-10L :) of course for a decent price. (in europe) :) thanks for your Answer Jacob
