Last week there were some nice clouds. Today just a hazy clear blue sky. Hopefully there will be some clouds this coming week.

Our Texas outlook is the same. Maybe time to look for dust clouds, insect clouds, clouds in my coffee, etc.

I saw this too late. So unfortunately I have no time to send in a proper contribution.

But when I am at home again I can still contribute a cloud picture by Oskar Barnack himself! That is a picture of a cloudy negative stored in protective paper.

In 2023 in the Leitz Museum Archive in Wetzlar I could look through the remaining Oskar Barnack negatives. It struck me that one negative was almost completely filled with clouds. Why would Barnack have made this composition?

My working hypothesis is that he self-sensitised a regular colour blind cine negative film so as to make it sensitive to the colours yellow and green. This procedure was used by Leitz for micro-photography as well. One can infer that Oskar Barnack experimented in the same way with 35mm cine negative film for his Ur-Leica.

In this way he could use a yellow filter so as to darken the blue sky and bring out the clouds. This negative could then be used to print clouds in prints from cloudless colour blind negatives.

In contemporary photo magazines one can find such recommendations. 'How to create clouds?' was one of those evergreen subjects.

Back home again I found the clouds negative by Oskar Barnack.
This negative is on a filmstrip with three other negatives.
It is indeed covered in protective paper.

For this Barnack challenge I have only selected the negative with the clouds.
So I left out the negatives on the left and on the right of the filmstrip.

On the next page I present the negative as photographed in the Archive of the Leitz Museum in Wetzlar.
The protective paper is clearly visible.
For the second picture I inverted the image in photoshop so as to give an impression of what the print may have looked like.

It is my impression that Oskar Barnack did not aim at an independent composition.
He rather used the opportunity of his colour sensitive film to fill this negatives with clouds.
In this way he could use parts of this clouds-negative for inserting clouds in other pictures.
This was a normal procedure in the days that most photographic emulsions were still colour blind.

The left-out negatives give me the impression that the filmstrip is from a series of pictures that Oskar Barnack took in 1917 in the Black Forest.
One of these pictures even suggest that he used an Agfa Fliegerfilm in the Ur-Leica.
This Agfa Fliegerfilm was produced for a new generation of German aerial reconnaissance cameras. 

This is a big subject.
I will come back to this in my posting on 100 years Null-Serie.

Here is the complete filmstrip.
The picture on the right is reproduced in Theo Kisselbach (1955), Das Leica Buch.
