Requested Aspect Ratio
By default, requested camera images are cropped to highlight the most relevant parts of the camera's field of view (see GetCameraImage). As a result, portrait aspect ratio image requests (e.g., 240x320) are not recommended, since they tend to result in images with useful content missing from the left and/or right edges. Instead, a landscape aspect ratio of 3:2 (e.g., 360x240) is recommended.
