World Wet Plate Day 2024 – my plate

This year I had to shoot my plate for the WWPD very early, because I was booked the whole WWPD. So I shot this one some minutes after midnight. Happy World Wet Plate day everyone. The wet plate force is strong in that one! For more wet plates from the WWPD visit: https://www.wetplateday.org/

MayThe4th be with you “floating lens”

I did live stream it, here you can watch the recording

    DIY Ambrotype/Glass cleaning clamp for wet plate photographers

    Cleaning ambrotypes is a very tedious task. Especially when you want to prepare many plates. Thats why I wanted to get one of these glass clamps for cleaning. Most clamps I found online were not what I was looking for. Then I found the one Adam Savage made for Gary Oldman: https://youtu.be/4MVxJNawefM?si=sxB__Zr7kcl_g1rQ
    I guess lots of you guys did not know that mr. Oldman is also one of us who the path down the rabbit hole to work with the wet plate process.
    Inspired by the wonderful design of Adam Savage I started to design my own version that can be 3D printed. Even the wooden version of Adam Savage is much more beautiful, my printed design may be easier to clean. You can download the files for 3D printing from my Patreon page
    No membership is needed, but consider it if you want to support me. Or buy me a tea or PayPal me

    Darkroom ventilation and humidity control

    This topic sounds very simple but is probably more complicated than you thought. In this case I will explain the solution for my darkroom, but it could also be a solution for other cases.
    In this video I show you the construction (with a nice fail) process and the whole ventilation system including how I reduce humid air in my darkroom. Underneath I share some additional information to the video.

    As said in the video, if you work with chemicals like ether and alcohol, a mask alone is sometimes not enough. Because when there ar enough fumes in the room, your skin will absorb them and that way it could damage your liver. Thats the reason I always ventilated my pouring room in-between bigger wet plate sessions. When you ventilate typically with an open window, you will cool down or heat up the room (depending on the season), beside that you get for sure some dust into your rooms. Luckily my friend Wolfgang has a company ( https://www.leit-wolf.at ) who is specialised in how ventilations system and opened my eyes. Thanks a lot for that! Let’s start with the preparation. To make this ventilation system work, I needed some holes and for that I commissioned a company to do some core drilling.

    I marked the places for the ventilation pipes, so the company knows where to do the core drilling, so there are no electric wires in the way (sarcasm – see why in the video)
    to make the drilling as precise as possible for the ventilation system, I ordered the “shell installation kit WS 75 RSAP” https://www.maico-ventilatoren.com/en/products/details/p/shell-installation-kits-g61068/ws-75-rsap-p124746 this makes masking the holes very easy
    this monster of a core drilling machine made it possible to get fresh air into my darkroom.
    Because every hole needed to be drilled wet, they brought also vacuum machine that sucks all the dirt and water in. In any way you will get lots of dirt into your room, but they cleaned up very well.
    after all holes were drilled, I mounted the shell installation kit and glued the ventilation pipes into the wall. For sure not my most beautiful job, but at the end everything worked as expected.
    The next step was to mount the Ventilation unit on the wall. I chose the “Ventilation unit Maico WS 75 Powerbox H” because it has a heat recovery that reduces the cooldown of the rooms. There are also dust filters build in. Beside that it only consumes between 5,2 and 11,5 Watt. You can find lots of information about how to set it up (video and documentation) here: https://www.maico-ventilatoren.com/en/products/details/p/ventilation-units-g61071/ws-75-powerbox-h-p124754 – just click on Downloads/Videos. You can also switch the website to different languages.
    Here you can see the nearly finished ventilation system. The rectangular part near the floor is a silencer that makes the very silent ventilation system even more quiet.
    one of the last steps was the initial configuration of the ventilation system. Like moste things today, thes is pretty high tech as well and you only can set it up with a computer.
    The system comes with a control panel (https://www.maico-ventilatoren.com/en/products/details/p/control-panel-g61464/rls-g1-ws-p125256) that shows the status and also lets you control the unit. I bought a voc sensor for my unit ( https://www.maico-ventilatoren.com/en/products/details/p/sensors-g61463/ws-75-voc-p125253 ) This measures the volatile organic compounds in the air. It’s measured with ppm (parts per million). The higher the ppm, the more the air will circulate through the rooms. That means, if I pour some plates and the sensor “smells” the ether, the ventilation system turns up the power.
    outside I mounted the Combi-wall connections Duo KWS E (https://www.maico-ventilatoren.com/en/products/p/combination-wall-connections-g66762/duo-kws-e-p119350) This avoids that animals would use my ventilation system for some sleepy time. But it also avoids an “air short”.

    The finished ventilation system blows fresh air into my studio and sucks it through my darkroom and pouring room back outside. With that I have always fresh air in my workplace. My studio is a pretty new building, but the other parts are old and are more humid. While ventilating in the winter mostly “dry” air comes into the rooms and there is mostly no need for the dehumidifier to start. Only when the relative humidity is about 60% I start an automation that checks how much my photovoltaic power plant is genarating and if the sound generates enough energy, I start to dehumidify my darkroom

    But when is it save to ventilate? I learned a lot and thought I just check the humidity outside and inside. And if the relative humidity is lower outside, I thought its save to ventilate. But I was totally wrong, you have to calculate the absolute humidity with a calculator like that. https://www.omnicalculator.com/physics/absolute-humidity

    The absolute humidity is measured in g/m3 and it changes with the air temperature. Here are two examples:

    lets assume it’s winter and it has 8 degrees outside with 70% relative humidity for some funny reason. Even your relative humidity is lower than the outside, its save to ventilate if you want to get the humidity down.
    Now the relative humidity outside is much lower than inside, but the absolute humidity is because of the temperature much higher. If you want to reduce humidity in your room, that it would be the wrong time to ventilate. I am working with a friend of mine on a script that compares the absolute humidity from inside and outside and when it’s save to ventilate you can start an automation or get a notification. I will upload it here.
    It was lots of work (See also my other darkroom article https://blog.markus-hofstaetter.at/2023/12/my-new-easy-to-use-darkroom/ ) but now I am super happy with the solution. With the whole new darkroom finished I am like a little kit when I start to work there.

    I hope this was helpful for you guys as well.

    My new easy to use Darkroom

    After moth of renovating my Darkroom, I am finally finished with it and can show you what I did to make my life easier.

    One of the main things in a darkroom is the sink. I looked for age to get a fitting one, but couldn’t find any. But my good friend Lois knows somebody who knows somebody and with that I got a custom made sink that was a lifesaver. Thanks a lot for that!

    Fitting everything in a small space is making everything more easy.
    Another thing that made my life easier is the Darkroom Winch that you can get here: https://www.borutpeterlin.com/shop/hardware/darkroom-winch/ This saves so much time, because otherwise I would be standing there for hours rocking trays.
    Beside rocking trays, washing prints and plates is another thing that has to be done, thats why I build this watering system out of plumber pipes from the diy marked. I am sure you can find yourself similar parts near you. I only had to drill holes into the pipe and find some kind of holder for it.
    I just had to get an old stop watch for my darkroom and this one from Junghans fits just perfectly in there.
    Dangerous chemicals need to be locked up, thats why I use an NFC lock with my stainless steel cabinet (links to the lock and 3d print files can be found at the end of my article)
    Red light, yellow light, bright light, dark light – all these scenarios are possible with my Philips hue system that I use in my darkroom. Just with the click of a button I change to whatever color I need and I also build a protection cover, so nobody accidentally changes from red to white. You will find all prints on my thingiverse: http://thingiverse.com/mhaustria
    Humidity and temperature can have an impact of your work and also can have an impact of the darkroom. With this sensor I can easily read the values and can create automation because of it. More about that in my second darkroom video that focuses mainly on ventilation and how to save money with that.

    Here are all the links to the tools I used, consider buying that stuff locally as well.

    my portrait at one of the most beautiful places in Austria

    One of the most beautiful places in Austria – During poppy flower season there is a beautiful place to visit here in Austria. The Mohndorf (poppy seed village) in Armschlag. At exactly that place our „Menschenbilderausstellung“ (human pictures exhibition) was exhibited with one of my inspired series portrait. I love that place. Beautiful scenery, good food and a wonderful exhibition.

    Should you buy a scratched lens?

    This topic brings often lots of emotion up. And honestly I was struggling myself buying lenses with scratches for some time. I still do. Thats why I wanted to take a closer look into this topic . Gary https://www.instagram.com/garygeezerphotoart/ sent me a scratched lens some time ago and therefore made this video possible. Thanks a lot for that!

    This old Ross projection lens got lots of fungi and scratches all over the glass

    But this is not the first scratched lens that I got, I bought a used canon 24mm lens a while ago from a shop for very little money. I knew already that the little scratches will not affect the image, but I still had a bad feeling. After Some years I can assure you, that all images that I shot with it looked great

    my scratched canon 24mm lens – no issue at all to work with it

    You still are not sure if you should get a scratched lens for a good price? Then have a look at my video, where I show how I shoot the plates with a scratched lens. I discuss this topic with a fellow wet plate artist who is also a specialist in renovation of historic photographic equipment: Denis of wetplatedreams.com Denis started recently a YouTube channel where he spreads his knowledge of historic lenses.

    As promised I posted the hires scans of the plates underneath. One plate is shot with the old Ross projection lens and one is shot with this very new Zeiss Epic projection lens.

    This projection lens is as clean as it gets

    Can you guess which plate was shot with the scratched lens? Click on the highres crops to see them in full resolution. You can use the chapters of the video to chump to the part where I explain what plate was shot with the scratched lens.


    Shooting wet plates with this projection lenses can be very tough, because the dof is very thin. I also think that one of the lenses had some chromatic aberration. That means, that the blue light is focusing on a different distance than the visible light. This is sometimes also called chemical blurring or chemical miss focus with the wet collodion process, because the wet collodion process sees only some parts of the UV light spectrum (about 420 to 490nm).
    I can only focus on the light I can see with my eyes, but some lenses focus because of the chromatic aberration the limages for wet plates on a different spot. Thats how a miss focus can happen. But you can see how extremely sharp both lenses performed anyway. To judge the sharpness for image A, have a look at the top and the right side of the cropped scan.

    Even I knew what was the plate that was shot with the scratched lens, and I still mixed them up and was convinced I was right when I showed it to my intern, shows how similar the plates are. This was another point that went to the scratched lens. Scratches and fungus mostly cover only a small percentage of the lens and thats the reason it won’t affect the image that much as you would think.

    If you want to support me and get deeper into topics like that, you always can book a workshop or join our Patreon team. Or just book a portrait session . Check also my Instagram channel for latest news: https://www.instagram.com/mhaustria/

    So what does that mean, should you buy scratched lenses? From our perspective, you definitely can buy scratched lenses. You will save money and still get the same results. It only affects the value. As always, it depends how big the damage of the lens is. More about that in my video. If you buy lenses as an investment, you probably will look for a mint lens, but here you have to put lots more money on the table.
    At the end, it all depends on your needs.
