I can only hope that you employ sealed plastic bags to place your lenses in after such endeavors full of silicon dioxide desiccant packets (and sealed) to hope to extricate the moisture from the inner workings of your lenses. Gut check.Early Morning, Shepard State Park - Gautier, Mississippi
Summers in Mississippi bring lots of rain, and consequently lots of humidity. When I take my lenses out first thing, they instantly fog up from the humidity compared to my car. I wipe them down and get to shooting. I've often thought it would be interesting to see how they image with the fogged glass. This time, I guess the inside surface was also very foggy or re-fogged and so I got my test, unintentionally. I like the result.

We no longer have lens technicians that can clean fungus formation from the inner workings of large format lens and recolluminate these lenses to optimal performance so it is all on us to avoid this issue. I can't tell you how many lenses i acquired in the used market and sent to John at Focal Point when they were still in business to remove fungus from the inner workings of models lenses that were a result of high humidity conditions these optics were used in without consideration of these risk variables.
I live in the deep south. The humidity is just life. It got a quick wipe from my t-shirt after this photo and then went back on the shelf when I got home. I've never had issues, and this just happens for a few minutes when acclimating to the environment after getting out of an air conditioned car.
You can espouse all of the personal minimal effects from humidity in your specific situation you want. But the fact remains that the correlation between humidity and the inner surfaces of lenses sets up a less than desirable condition for the possible initiation of fungus that is not a good situation for an expensive plasma or for that matter any lens. Under magnification it was amazing to me to see the initial stages of the formation of fungus that does not register to the naked eye. Only when the condition grows and amplifies to what I call "observable" does the photographer accept the fact that they have a problem. By then the condition is in the severe stage and the adverse effects on image quality are undeniable.
I live in the Rockies where humidity is really not an issue. When I traveled to Hawaii recently I kept all of my lenses in a sealed quart Zip Lock bag with 6 small SO2 desiccant bags in each lens bag specifically for this issue to draw moisture out of a designed limited area. Why? The seals on lenses between the optical components are not sealed to humidity. We as photographers need to own this physical reality and own it as well as mitigate it. The question that needs to be asked and answered deals with a physical reality in the world we live in.
It is easy for humidity to get into the inner workings of a lens. Why? Moisture seeks dry places to hang out. Getting the moisture out of a lens is not going to happen on its own therefore the smart move is to keep lenses protected from these conditions when they are not in "use" and using desiccants in these sealed bags as SOP after the images from these lenses have been made.

Great picture, Reinhold! Nice gradient of light on the rock.
First, hi everybody and thank you for your kind words! My english isn't very good. So please don't be angry if I don't write so extensively or make mistakes. But I am very interested in your opinion about my pictures!
