Start a mission in the space program that requires advanced equipment (i.e. a Scoop).
Run all tasks in the mission except taking photos. (Exemplary, because it's the most basic task that is already available from tech level 1 onwards).
Abandon the first vehicle, that has the mission assigned.
The simple tasks "take photo" remain on the map.
Check the mission on the map, all available vehicles from all tech levels should be selectable (all with a basic photo device mounted).
Select a basic vehicle (i.e. T1 Lander) and modify it - this will take you to the lab. (Select "Vehicle Details" -> "Modify Vehicle")
You are not able to launch the new vehicle directly from the lab, because equipment is missing. (Button "launch" is greyed out and does not work) Check requirements on the lower left of the screen.
It's not just a photo device (and of course power & antenna), but also all the initially required devices as scoop, apxs, etc.
