alt Hacker NewsI have a question: how can I print HDR? Is there any HDR printer + paper + display lighting setup?
My hypothesis are the following:
- Increase display lighting to increase peak white point + use a black ink able to absorb more light (can Vantablack-style pigments be made into ink?) => increase dynamic range of a printable picture
- Alternatively, have the display lighting include visible light + invisible UV light, and have the printed picture include an invisible layer of UV ink that shines white : the pattern printed in invisible UV-ink would be the "gain map" to increase the peak brightness past incident visible light into HDR range.
What do you folks think?

You would need a very strong light surrounded by a darkish environent. I don't see a point in "HDR Paper" if you need to place it under a special light.
Use projection mapping, instead of lighting the photo uniformly, use a projector and project a copy of the image onto the photo, thus you get detailed control over how much light the parts of the image receive.
Alternatively, use transparent film and a bright backlight.
