Re: resolution dpi ppi
[quote="tinkering":2odwwclj]If I raise the ppi from 200 to 300 it appears to make the image size smaller. Is that an OK way to raise the resolution if the reduced image size is acceptable?[/quote:2odwwclj] It IS making the image smaller, and yes, if you're happy with the reduced size then this is ok. You're not actually [i:2odwwclj]adding[/i:2odwwclj] resolution when you change this number - you're just 'redistributing' it. To actually add resolution you need to check the box that says "Resample Image" in the Image Size dialog - there will be some quality loss if you do this, however.
