Are you a health-worker who needs to send an image of an observation from under the lens of a microscope and have a diagnosis confirmed by a reference centre?
There is no need for a computer, nor access to a broadband internet connection! Neither is there a need for sophisticated photographic equipment or tricky, expensive adaptors and dedicated extensions.
You don't need to waste time or money looking for any of these!
All you need is a mobile-phone with an integrated camera and the capability to send MMS. Such access to a mobile network with this capability is rapidly becoming available in every corner of the world, including the most remote areas in disadvantaged countries.
Simply place the lens of your integrated mobile-phone camera on the ocular of the microscope and take the picture - then send it via text or email.
The idea is free - just try it out.
