In terms of the best effect size, if the developed photos can be placed at 3. 1× 2.4m, if they are developed, they can be placed at15.2×10.1m.

But with my practical experience, I can do anything bigger.

However, it should be noted that the actual effect has a lot to do with the camera. A small DC12 million pixels must at least divide the above value by three.

I calculated it according to the digital SLR in APS-C format. If you change it to Canon G9, there should be no problem with 10 inch. If it is bigger, details such as highlight overflow will be obvious.
