Newbie Question. Query #1 I am doing the Mike Matas Life Poster. When I go to the Page Set-up of Iphoto, the measurement is in centimeters (cm). How do I change the paper size and margin to inches? I tried searching the iphoto help and I could not find it. Query #2 a) Mike Matas instructed saving the Life Poster to PDF and converting it to TIFF (for transfer back to Iphoto). b) Also, he instructed to open in Photoshop at 200 dpi. May I ask the gurus why the two items above? That is why the need to save to PDF then to TIFF and why 200 dpi? Appreciate it. P.S. - Had a fun time doing this but there were some kinks. After changing the pics to 4x3 dvd, some pictures when already laid out in the Poster (cum contact print) were not right - sometimes in portrait and sometimes with space.
