Everyone,

I recently received an email that I need some assistance in responding to.

Here's the inquiry:
I'm sowrking as a volunteer in Swaziland with Dr. Pons at Good Shepherd Eye Clinic, building up a Diabetes Retinopathy Screening service.. We are looking for how to find a pc-software to being able to change a fundus image to red-free.
We all know it's very helpful to look at the images in different wavelengths so if you please can give us any idea.

Your web page is very good and helpful by the way.

Realistically if the file was captured in a raw format, and was captured using the red free wavelengths, then in theory you could use an image editing software. Converting the image to black and white initially would help, but putting it to B&W while keeping the image in an RGB format you could turn off the R layer and have simply the GB layers, but really, that may not be quite the same still.
