The petrifilm center is only 5cm in diameter. If the camera is 2MP, the focus distance to pixels wide are as follows:
5cm = 1200 pixels 10cm = 600 pixels 15cm = 400 pixels 20cm = 300 pixels.
We need to check what the minimum number of pixels is for accurate colony counting and that the camera has a macro mode capable of doing such close focusing.
