There isnt a lot of different between gloomy
conditions and in the dark color wise,

SO why don;t the military use such a system
rather than rely on image intensifiers.

Essentially because the smartphone technique is
so recent and it remains to be seen if it will in fact
be used by the military much more in future.

So nothing is avaible now at this present moment is there.

Thats less clear. They clearly are rather secretive about
what they use, for a reason, and dont have any reason
for true color night vision. Heat sensitive is what they
need because its impossible to stop the humans
being visible from the higher body temperatures etc.

The current military stuff has in fact been around for
decades now and is primarily physical technology
rather than the dramatic computer assisted tech
that smartphones use with so much computer power
available in the top of the range smartphones.

So nothing is avaible now at this present moment is there.

Record's stuck.

Perhaps T i m is willing to spend over a grand on a single camera.

He hasnt been clear about what he wants it for.

Why arenlt the wildlife programmes
you see on TV at night in full colour ?

Basically because it can be more useful in that
situation to have IR illumination triggered by
the movement of the animal when you are
often counting a particular type of animal
and all you need to do is work out which
type of animal it is and you mostly dont
need color images to do that.

Easier to count & identify them if you can see them in colour.

Thats bull**** with the color, particularly with the nocturnal stuff.

There might just be a reason why the most
colorful birds and fish mostly arent nocturnal.

They mostly arent used to just count the number
of say lesser spotted ring tailed nocturnal lemurs
which have a distinctive red blaze on their backs etc.
You're just counting say beavers and not domestic
cats etc or koalas or possums etc and all you need
to see is if its got a tail etc.

I doubt T i m is looking for lesser
spotted ring tailed nocturnal lemurs.

Duh.

He's more likely to be looking for Brexiteers.
But only he knows what he wants.

And is being very secretive about it.

Bet he's a pervert or a gutless streaker or a terrorist.

just a much lower level of the colors when there
isnt any IR illumination, just a long exposure or
adding multiple frames electronically.

That's who they take pictures of the deep space to show
distant stars and galaxes. But there is light out there to see.

Not with black holes. Thats why they are called that, stupid.

There's harwkins radaition coming from black holes

But even you should have noticed that that isnt visible.

and you can with the correct equipment, skill
and knowledge photograph a black hole.

Only dur to the lack of anything visible from there, stupid.
