Good morning Flexers,
I’d like to recommend an MIT video on YouTube by the great Grant Sanderson. Here is a link
He talks through image manipulation using the Julia programming language (which ia available on the Pi but I would suggest something more powerful) .
So if you want to manipulate images from your microscope, say, to change colours, resolution, look at edges, I’d watch the video. I’m impressed enough with the simplicity of Julia to learn it after watching this video.
