I 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?
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.
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.
usecase: a photo exhibition that wants to show pictures in HDR = An HDR print setup (i.e. paper + appropriately controlled lighting).
Haven't you ever been to a photo exhibition ?
