i tried to search but overwhelmed by the search results. thus, i created a thread. hope it benefits other too
1) what's the max size a 3Megapixel photo can print?
2) anyone got a table which can show the max size different image resolution can print up to?
3) is it true that digital photos printing at lab means cropping due to the 3:2 ratio?
4) for photo, the "4" in 4R means 4" width or 4" length?
