100 year-old camera’s photo of my garden

So, using the recently acquired “plate holders” to hold the photographic paper in the back of my, now modified, Boots Half Plate Mahogany camera, I have taken and processed some successful pictures.

Taking the exposure using my iphone and the “Lux” app and judging the ISO of the paper to be 25, I made 3 exposures of the paper at f32 for 4s (as Lux indicated) and also, 8 and 16 seconds. As 8 seconds was the most successful. Seeing as the app had suggested 4s as the correct exposure, I will assume now the ISO equivalent of the paper is 50 and work on that basis for the next tests.

I developed the paper and got three well focussed images with a full tonal range.

The images produced are of course negative images. These I then scanned in to the computer and through photoshop inverted the tonal range to give the black and white image you see here.


The dynamic range is too great and I understand “flashing” the paper before use can help reduce this. That’s the next experiment.
