I.S.O. ,,, international standards organization
ya know,, this i.s.o. thing has been a thorn in my side ever since i got my first digital camera.
now jump ahead to the digital age,,
no film at all,
so no silver particle differences
but still an I.S.O. setting,,, hmmmmm, are we being manipulated here??? frikin big brother,, ha
anyway,, i.s.o now days is simply an image degradation button, and is only a tool to use when light is low, tho one should be using a tripod when light is low
keep the i.s.o. at it's lowest setting, and leave it there, if one is the least bit serious. one should feel guilty every single time one uses it.
i will point out the absolutely legitimate creative purposes of the i.s.o. setting as well. nuff said about that right there
i maybe should have been much more elegant in my explanation but i have this thorn in my side, and it bloody hurts,,
