Hi I have a Canon 400D camera. I take photos on the large quality setting as I need to print into A3 size photos. When I bring up my pictures on photoshop the "image size" details are:
Width 2892 pixels
Height 3888 pixels
Width 91.44 cm
Height 137.16 cm
Resolution 72

I thought that in order to print good quality photos, the resolution needs to be somewhere near 300!
Can I change the resolution to 300 and reduce the document size to an A3 document size? Will that reduce the quality of my image?

Alternatively, can I just print it straight from the camera with resolution 72?
