Can I take pictures with ultraviolet light?

Photography with ultraviolet light source is called ultraviolet photography.

Its recorded spectral range is 120-380 nm.

For mid-ultraviolet photography with a wavelength of 20-380 nm,

Ordinary photosensitive film or dry plate can be used,

While for sectional photography with a wavelength shorter than 200 nm,

Special B photosensitive material with gelatin content less than 0. 1% is needed.

When shooting, use a special timely glass lens.

And an ultraviolet filter is attached to the front of the lens,

Prevent visible light from interfering with ultraviolet images.

Or directly irradiate that subject with an ultraviolet light source,

Expose photosensitive film. After processing,

This photographic method is often used in medicine, archaeology, bacteriology research and judicial expertise.

There are two kinds of ultraviolet photography, direct ultraviolet photography and ultraviolet fluorescence photography.
