Where do seeing and hearing fit in the 4fs?

Or don't they?
Noticing a cool breeze on the skin, perhaps "cool, pleasant" (for example).
Noticing light through eyelids - ?
Are these sensations to be noted elsewhere?

I tend to note the effect that seeing and hearing seems to have on my thoughts and emotions. When seeing something that gets my interest I note 'interest' or some emotion may arise like 'desire' or 'aversion'. When hearing a bird sing I may note the mental image that comes to my mind 'imaging thought'. Some scents get noted as 'remembering thought' or 'nostalgic thought' and if I see some beautiful play of light on a surface I note 'appreciation of beauty'.

meekan,

I think the pure sensation of seeing is 1st foundation (pleasant image = 2nd).

Thanks, guys!
I've actually done both, i.e. Treated it as a bodily sensation, and also just noting the effect of it.
Haven't really understood which it is,
Traditional ms-noting, just note both, I guess...

I see (!) that there are different interpretations of this!
Hah!
