It was scanned by a lab, not myself.
That doesn't mean it's been well scanned. I had a roll of 35mm developed and scanned by Peak Imaging, which is one of the best specialist labs in the UK, and found I could do a far better job myself on my Epson V500, but manually scanning each image is very time consuming, and so can the subsequent processing be if there are any dust spots or scratches.
Peak Imaging's scanning isn't cheap, either. It's superior to what you will get from a High Street lab.
