Read the following context and answer the question.
Context: However , I was playing around with the resolution settings on my scanner program and wanted to do a little more . So the .zip below actually contains individual , higher res scans ( Set at 300 dpi instead of the usual 200 ) . I also added AdellxRozalin scenes from both the battle ( Chapters 1 - 3 ) and the one 's you 'll be seeing below ( Chapters 6 - 7 ) . Of course , if you wanted lower res scans , I do n't mind going back and re - scanning them .
Question: What may be the reason they were playing around with the settings ?
Answer:


They were using trial and error to learn how to use the scanner .
