Heinkel, the idea is good, but:
1 - Actually you press the STRAT button and know almost everything about the status of the selected base.
2 - Even disabling STRAT info, bases do not need more than few minutes to be restored, So, while you are returning with the film the situation may change drastically.
A more simple idea may be as follows:
STRAT info is dissabled by default for all enemy bases as well as factory/HQ info. But you may go to these places, "take some pictures" and then the strat info for that base/factory/HQ is enabled for a period of time based on the ammount of pictures taken, and you get some perks for the recon mission.
For example, recon planes may take a "picture" per minute, and each picture adds 10 mins to the total time STRAT info is going to be enabled for that place. So, if you fly over enemy HQ and keep there taking pictures for 10 mins (taking 10 "pictures"), once you land at a friendly base, strat info about the enemy HQ will be availabe for the next 100 minutes.
