Finally taken the plunge and bought a digital SLR... and realised how little I know! First question - when I transfer pictures to my laptop, they go across at 72 PPI, no matter how I do it. The pictures are huge - 48" x 32", but at this low resolution... or have I got it all wrong? I know when I transfer file from my old Ixus, they used to be 180 or 300 PPI. Am I doing someting wrong?
