Camera: 3d printed Large Format (4×5) camera with homemade bellows
Film: Cat Labs BW
This was my second test with trichromy photography. I took three photos, one with a red filter, another with green, and another with blue. Then developed the black and white film and scanned them. Then combined them back with the filters re-applied and tried to match the photos back.
With black and white film there are a lot of intricacies to be aware of. For example, the filters may have different density ratings so they will not be exposed the exact same even with the exact settings on the camera. This causes brighter and darker areas to skew towards the colors that the filters that let in more or less light.
Movement in frame is an intentional part with the modern usage because seeing the same leaf in 3 separate colors can be interesting (see top right). Matching the photos themselves is difficult so you have to pick static point of reference (here I chose the tree trunk).
Lastly, the file size is enormous. Scanned in, each frame is more than 1.2 gb. So adjustments take time and patience.
This is one of my favorite pictures even if the colors aren’t accurate on the leaves (these filters were off a little from true rgb, I do have new ones that are supposedly exact to try out). It was a bit of work, and from taking to processing, to scanning, to compiling, and to finally uploading took some time as well.
