About 1 minute into this documentary on NASA's 1960s days,
there is a shot of a Gemini capsule in space.

https://youtu.be/Rx5rwivpdEU

or a still iamge at
https://ychef.files.bbci.co.uk/976x549/p02mrr3x.jpg

How were such fopotage/photographs taken without any umbilicals showing
between the capsule and the point of view of camera?

I know there were at least 2 missions with an Agena rocket docking. But
if the footage was taken by uncrewed Agena before or after docking, how
would it have gotten back to Earth. I can understand the video being
broadcast over airwaves to ground, but wouldn't pictures require the
film go back to Earth to be developped?

You do know that you can use Google to do an image search?

Thanks, I had pulled up the list of Gemini missions and didn't see that
there have been 2 Gemini in space at same time. The last 2 missions were
attempts to demonstrate docking with Agena, so I didn't think that
previous missions would have had multiple ships up at same time.

Was Gemini-6 and 7 the last time the USA had 2 manned ships of its own
in space at same time?

A most excellent documentary on early days of NASA and life of the
average astronaut :-)

The opening sequence in that one had NASA footage of early space, which
inluded a view of a Gemini from aafar, and that was not "Hollywood"
since back in the 1960s, they didn't have CGI to create such images, so
that got me cruous on how this was shot.

Crew Dragon has already done this.

https://en.wikipedia.org/wiki/SpaceX_Dragon_2#Crew_Dragon_flights

https://en.wikipedia.org/wiki/SpaceX_Crew-1
Crew-1 undocked from ISS on 1 May 2021

https://en.wikipedia.org/wiki/SpaceX_Crew-2
Crew-2 docked to ISS on 24 April 2021

So, there was about a week of overlap between them at ISS. Soyuz
usually does much the same when Russia rotates crew.

No, Apollo 9, 10, 11, 12, 14, 15, 16 and 17 all had two manned ships operating at the same time. If you consider the ISS as a US ship, then all of the shuttle flights to it plus the recent SpaceX missions would count.

I was thinking in the context where there had been discussions about
NASA would have had issues having 2 shuttles operational at same time in
orbit (radio comms, telemetry etc).

When a Dragon is docked on station, does it go to sleep and depend on a
data connection to station for any communications, or does its radio
remain active and SpaceX still control/monitor it 24/7 ?

Only SpaceX knows the answer to that question.

But, I'd imagine that Dragon would not be completely powered down simply
because you wouldn't want to chance that it wouldn't power back up in an
emergency. And if that's the case, I'd imagine that SpaceX would be
monitoring it 24/7.

But if a ship is docked to station, it is possible its own radios are
powered down and it is connected to the world via the ISS's comms
infrastructure.

Even if SpaceX developped a command/control protocol that gives each
ship its ID, allowing it to send commands to a specific ship when many
are in the air, there is the issue of ground station and TDRS network.

Each SpaceX ship needs to exist as its own routable entity so commands
from Hawthorne know which ground station and TDRS satellite to use to
reach that one ship.

Obviously, Shuttle and ISS were independantly routable, but were each
orbiter independnt from the others or were there all considered the same
ship from point of view of ground stations and TDRS?

And back in Gemini days, did both ships transmit telemetry constantly,
and if so, how did they co-exist without crushing each other's
transmissions?

Why would you assume telemetry would use a single frequency? Their are thousands of spacecraft in orbit from dozens of countries.
