Help using exiftool in terminal "no file specified"

[classicbs]

Hi there I'm sure this is a real simple fix and apologies for my complete nobleness.   I'm trying to use exiftool to reduce exposure on all the photos in a time-lapse sequence shot with ETTR.  I've worked out how to get the de flicker working in light room but I want to also batch reduce exposure.

On mac put all your images and xmps in one folder.
open up terminal, enter this, exiftool -Exposure2012+=+*.** /drag folder here containing cr2's and .xmp's

Where the *.** is enter the amount you want to set, eg 0.05, next to the number you have chosen, too the left is +, +=over expose for under add -

I tried this but I just get an error saying "no file specified"

Any ideas?
Any ideas?  Many thanks
