    here’s another fun thing I tried recently, comparing dying autumn leaves in visible and infrared light. Love how both are vibrant in their own rights, especially the lakes edge in IR, the second photo #photography #infrared

    A lakes coastline with a bunch of autumn coloured trees. They range from a dark green to a muddy yellow and a dark but vibrant red. The sky is grey the water muddy green. An overall green and dark scene
    The same scene, the coastline with trees and buildings behind them trees. The water is bright cyan this time, the trees bright pink, cramy white and beige yellow. All with very different densities and textures. The sky is cloudy but bright. A very vibrant and happy scene. Everything is much more visible than in visible light
    A very tall tree in autumn, it is bright yellow to red, with a bit more green leaves at the bottom. A person is walking beneath the tree
    The same scene, but the tree is now pale, bright pink towards the bottom, creme beige at the top. A very different vibe. One can see the gradient of leaf death forming from bottom to top. A person is walking beneath the tree

    It’s neat how the IR lake-photo is much clearer and much more readable in terms of tree differentiation. I can 100% see how this can be useful in agriculture/forest management and heath monitoring. I wonder what other wavelength(s) would be interesting here.

    You can in the second set of photos also clearly see how dead the leaves are, the more IR they reflect, the more pink they are, the more healthy they should still be. The bottom ones on the tree are much more pink than the upper leaves

    I wish a split lens existed, that allows for two cameras to capture the exact same frame. That way you could have one record IR, the other regular footage.

    By the magic of post-processing and auto masking you could record an insane dream world, where your actors or some items are their normal colours, while the surrounding is IR.

    Would be especially cool on video

    @Purple oooh, yes!! I thought about modding a 3CCD camera from RGB to polarisation. I wonder how easy it would be to make it a 3x3 CCD camera (as in replace the monochrome old CCDs with modern RGB Bayer ones, they come in the same size), you would have the opportunity for up to 9 channels!

    @janamarie @Purple also wonder how it would look if one adds the ir info to the visible for a wider spectral range and then squashes it into the visible.
