Lately, I’ve been experimenting with filter stacks that pass UV, blue and green. It is interesting that both methods can result in quite similar images. I just want to show an example today. Within the next several weeks I’m planning to elaborate more on the topic.
Ranunculus ficaria, Bensheim 9 March 2014.
Camera: Panasonic Lumix broadband modified, with the EL-Nikkor 80mm/f5.6.
Visible light image (Filter: Schott BG40, 2mm)
UV image (Filter: Baader-U)
Bee-colours (Filter: Schott UG-5 + S8612, both 2mm), UV-flash
Bee-colours with channel swapping (blue->green, green->red, red->blue):
Image without any filters:
That's it for today. I will be posting more images and documentation on the method within the next several weeks.
