@robz just to let you know this wasn't "inverted" (not sure what you mean)...I would have thought the refraction would be upside down, but not in this lens ball. aside from cropping, this is sooc
@granagringa Now that is interesting! It must have something to do with the focal length of the curvesand the positions of the object and the image - it would be a great physics question for a senior class!! I assumed you had turned the whole photo upside down - probably because of the positions of the blurred yellows and greens in the background. Thanks for you response - as I said - most interesting. Cheers Rob
@robz if that senior class figures it out...let me know!! I wasn't sure ifvyou meant color inversion, left-right, or upside down...but still don't know why it works....hmmm
@granagringa Now that's getting doubly tricky! What a good lens diagram that would make!! I'm afraid I don't know enough about camera lens and their focal lengths to be able to make any sensible answer - but it could be an explanation - a double inversion. How cool!
