What do you mean by "untouched" scans?

The scan is delivered untouched from the scanner, meaning that it is not prepared for any particular output. There is no post production work such as spotting, touch up, color correction or sizing. There will undoubtedly be imperfections in the scan that an end user might need or want to improve, but the quality of the scanning is quite good nonetheless. You may want to use Photoshop, Photoshop Elements, or another such photo manipulation software to improve your output results.
