as a beginner i am still amazed at the properties binos add to our eyes! more than magnification and light gathering today i noticed another phenomenon.
it is lowish light, grey and raining yet still enough that a backlit bird 20 metres away in tree tops can be identified, in this case, as greenfinch using 8x25.
however, the window i am looking through is covered in rain drops and in the bino view i see none. not even a blur but perhaps a slight general fade or overall very faint grey. i am not even sure that is related as the day is dull.
so how does this happen, the bins cant ignore what is there but they see through the drops which to the eye are bright black and white. the focus wont pull back to them as they are too close to the bins but how does it 'ignore' them when they are physically present! or does the eye do the adjustment?
