After the photo was taken, the image is cropped to the bee hive frame. Now it's time to investigate its quality.
You can zoom an pan to determine if sharpness and lightning are acceptable.
Note: Using a flash-light might lead to insufficient quality due to inhomogeneous illumination.
If the image is too blurred or the tray has not been centred in the frame you just make another photograph. Otherwise proceed with the counting & estimation process.
