Thank you for the reference, I didn't even know there was such a thing as ultraviolet film. A few months ago I had to have an X-ray of my back, so the radiologist brought in a portable X-ray machine, and a thick plate as the target; it goes under me. So, they take the image and it shows up immediately on the display and stored to the machine's memory card. They can even use digital cameras to take X-rays.
It was the best example I could think of. I got thinking about it,and I remembered those long exposure freeway images.
Which is similar to what I said:
As photography improves more effects that used to require a studio and expensive equipment, then moves to portable professional equipment, then to consumer equipment. (This applies to other industries too,)
For example, there are two steps up from HD Video (1080p). The next is 2.7K, which I think is about double the resolution, then 4K which is quadruple. How much is a 4K camera? About a hundred bucks. For a few hundred more, you can buy a phone with an 8K camera. Both Samsung (Android) and iPhone offer phones that shoot video in 8K. Most TV sets aren't even available above 4K.
These cameras (2.7K, 4K, 8K) also take extremely high resolution pictures, in 7-8 digit pixel counts. For most people, the resolution on the inexpensive cameras meet or exceed what you could get on a multi-thousand-dollar SLR only a few years ago (which is why high-end cameras today are DSLR.)
