Well, I have made quite a few cyanotypes which require a lot of UV radiation for exposure.

They are very nice, albeit blue, and can be toned to yield other colors.

So, on to the other things. Do you want speed? Do you want to use it in-camera? Do you want to capture the image roughly as the eye would see it? These are things that Silver Halide does for us, so we need to find another method for giving us an all round imaging material, and not just a single purpose imaging material.
