Filters were rendered largely useless by photoshop and off-cam flash. They're good for protecting your lens though

This literally didn't help me at all. u think I didn't try google first.
What I am trying to figure out is what NM does does it mean how much light it let's pass through or it makes u have to take longer shots cause there tondark blah blah blah

i'm joking mate chill try on any shop whit online support...

nm is nanometers, which is wave length of light, each is hiding and showing different items on picture and IR filter is filter, which shows infrared (not visible) part of picture, here is example of IR and normal pic of same subject (found it for you online):








my friend, I have argue with you about this, there is still 2 very important filters you can't substitute by any PS filter try to guess what filters I'm talking about

only filter i use is a polarizing
ND's grad/normal are good at times

exactly these 2 cannot be substituted by postproduction
