Why Did The Police Of London Not Use Colour Photographs?

Just because something is invented, doesn't mean it is mass produced or adopted.

>color photography was invented in 1861 so everyone should have been using it by 1888!

3D VR 4K camera is already invented so everybody should use it, Isn't it?

I shouldn't be replying, but what the fuck.

Colour photography wasn't nearly as convenient then as it is now.
Why don't security cameras shoot in 300fps 8k today? Because it's really fucking impractical.

Even once colour photography became ubiquitous, it still wasn't done all the time because it was expensive. Many film photographers would still shoot the bulk of their "messing about" in black and white because it was easier to develop and cheaper to do.
It was only really digital that put an end to that, because it took no additional effort of expense to record an image in colour.

Because it was more expensive and the police had budgets back then. This isn't even the only reason.

"colour photography was invented"
Not really.
It still required three identical slides taken with glass filters, and then to be projected with the same filters.

Out of curiosity, are you Singaporean? This usage of "isn't it" seems to be particular to that country.

The first practical large-scale application of color photography was actually by Sergey Prokudin-Gorsky starting from around 1905, where he went around taking photos of the Russian Empire in full color, but even with modern restoration techniques, there are a lot of alignment issues between color slides and the simple fact that stuff moved between frames.
Reminder that this was the time when you already had to stand still for several seconds just for one exposure, never mind three consecutive exposures, you can be sure he had a few helpers on had to quickly change the film and color filter as he shot.
Also this was likely a funded expedition by the Empire's top brass, photography itself was a very expensive endeavor to pursue in the old days even without the complications of color, so why would some filthy policemen have access to this technology?
