Was the insertion into the Mars orbit controlled by ground controllers or was it automatic?

You can't control it by ground controller since there is a 7 or 8 minute time lag. Automatic is the only option and has been for the past 50 or so years.
That's a question with unlimited answers.
The cameras have been taking photos all the time, more than have been sent back due to the limited bandwidth and priority of telemetry data than imaging data. This will continue.
The orbiters orbit is changing, getting closer, so later photos will be clearer and clearer, but due to reason above, it is hard to say when and what will be sent back and published. The photo published may not be the clearest that the camera has taken.
The following is the mission profile. The recent Mars photo was taken before point 2 (insertion maneuver). Any photon taken after point 2 can be clearer when the orbiter is at or close to perigee. Now the orbiter is travelling from point 2 to 4 on a 11 days period. So my guess is that either it has clearer photo already taken at point 2 but not sent back yet, or it will need 11 days to take clearer photo and sent back. So my answer to you is within the next 2 weeks if CNSA decides to release them.
someone guessed ~118.9m/s, compared with the insertion's 585.8m/s it is much smaller.
| My guessed burning point | ||
|---|---|---|
| 火星捕获制动 | ~ 585.8m/s | 2 |
| 改变倾角 （改到86.9度） | ~ 118.9m/s | 4 |
| 勘查轨道 （2Sol） | ~ 92.4m/s | orbital change maneuvers from blue to green |
| 脱离轨道 | ~ 10.0m/s | |
| 回到轨道 | ~ 10.0m/s |

The strange thing is there have been so many U.S. Mars probe missions and yet I've not seen real-life footage of any of these probes doing the braking maneuver while approaching Mars. China is doing it for the first time and already CNSA is showing the braking maneuver the next day.
Let's see if NASA will show us the footage of the braking maneuver of the Perseverance spacecraft while coming in to land on Mars in a week's time.

Maybe they didn’t carry as many cameras or the cameras weren’t activated yet during the braking process.
