To control your camera successfully, Arsenal changes certain camera settings during shooting.
Persistent setting changes
When taking photos in manual mode or in smart mode, changes made to ISO, aperture, shutter, exposure compensation, and mode (either manually or through the smart mode) will persist after disconnecting from Arsenal. This is intended behavior; the thought here is that these settings will need to be reviewed/changed the next time you use your camera with or without Arsenal.
Temporary setting changes
When taking shots in Smart mode, Arsenal also toggles a few settings to 'on' before a shot, and toggles them 'off' after each shot. These settings are: metering mode, white balance, camera exposure bracketing, picture style, and hdrmode.
Potential issue when temporary settings persist
Sometimes, if Arsenal is disconnected from your camera during a shot, the toggled settings may remain since Arsenal is not able to "untoggle" them. The Arsenal team is working on a fix for this where as soon as the camera is reconnected to Arsenal, it will properly restore camera settings if this has not already happened.
If you experience this problem in the meantime, please contact our support team and we'll help you sort it out. If the situation is urgent, resetting your camera settings (to either the default state or your preferred settings) is a reliable solution.
