Auto Pv on H1

Tom Brown

Have just taken my first pix on an H1 with a P30 back.
As a Hassy novice have set the action to Pv to get the feel of the lovely machine.. The thumbnails are clear but when printed out via Photoshop on 5 x 7 paper there is a lot of pixelation. Would appreciate any guidance and apologize if this is very basic stuff.
