How do I run a shell script via AppleScript?

Question

Seems obvious, "do shell script" but that doesn't work for me.
I have an Automator app which runs a shell script, I'd like to take that into an AppleScript. My AS doesn't run the shell script. Perhaps "do shell script' is expecting the script to be located elsewhere? The rest of my AS runs fine, but the shell script doesn't.
repeat with i from 1 to count of items in exportFolder
  do shell script
          "exiftool -overwrite_original -Photoshop:CopyrightFlag='True'"
  done
end repeat
As I say this works within an Automator app, what changes do I need to make it work in AppleScript?
Thanks!

What is 'exportFolder'? Where is it defined?
Thanks, 'exportFolder' is defined earlier in the script. The purpose of the script - which is run from within Aperture - is to rename the selected images, export them (to the 'exportFolder'), reset the version name and, using ExifTool, add metadata which Aperture does not write to exported JPEGs.
I have a version of this which works in Automator but I couldn't see any clues there on setting the path to ExifTool.
Here's the full (modified) script. Currently it returns an error
Result:
error "No file specified" number 1
so I now need to understand if I can use 'exportFolder' (defined at the start) to tell Finder which folder to use.
-- Creating filenames by making Version Name  from the IPTC Headline and Filename (with hypens where spaces exist). The Aperture Version Name is used to create the file's name on export. Once exported the Aperture Version Name is reset to its original.
tell application "System Events"
          set exportFolder to (choose folder with prompt "Choose an export folder")
end tell
tell application "Aperture"
          set theSel to (get selection)
          if theSel is {} then
                    error "Please select an image or two!."
          else
                    repeat with theImg in theSel
  -- Creating a new Aperture Version Name which will become the exported file's filename.
                              tell theImg
                                        set headline to (get value of IPTC tag "Headline" of theImg)
                                        set AppleScript's text item delimiters to " "
                                        set theTextItems to text items of headline
                                        set AppleScript's text item delimiters to "-"
                                        set headline to theTextItems as string
                                        set AppleScript's text item delimiters to {""}
                                        set objectName to (get value of IPTC tag "ObjectName" of theImg)
                                        set newVersion to (headline & "-" & objectName) as string
                                        set name of theImg to newVersion
                              end tell
                    end repeat
  -- Exporting the files as JPEGs to chosen folder/Project Name using the Version Name as a filename
                    export theSel using export setting "JPEG - Original Size" to exportFolder
  -- Resetting the Aperture Version Name back to filename using IPTC Title (which should be the file's filename without suffex).
                    repeat with theImg in theSel
                              tell theImg
                                        set title to (get value of IPTC tag "ObjectName" of theImg)
                                        set name of theImg to title
                              end tell
                    end repeat
          end if
end tell
