    Beautiful to see this picture.

    For illumination; also try standing at the window of the classroom and look outdoors (without directly pointing the foldscope to the sun – because that’s too bright). By using different light illumination – you will be able to understand how light illumination impacts image resolution.

    Welcome to the foldscope community.

    Cheers
