We have a minilab here at a walking distance and the owner have a new Rolleiflex and very interested in my Rollei 35s. I took my EPP slides to him and he said it is impossible to scan them with Gretag Minilab and he said it was impossible to scan slides with flattop scanner.

Is he right ? Dont Gretag Macbeth Minilabs scan positives ? Or he doesnt know english and read the machines commands ?
