Re: GX7 image resolution

No, dpi (dot pre inch) or better described in digital world, ppi (pixel per inch), is something you instruct your printer to or print a hard copy of image. So, if at a printing resolution of 300 ppi, a 3000 x 3000 (9Mp image) can print out a 10" x 10" hard copy without any enlargement. Of course if you print at 100 ppi, you can get a 30" x 30" printout. When a printout of 300 ppi can look good at certain distance, at the same distance a 100 ppi print out would look less well resolved. That is the only difference between different resolution of printing.

However, it has nothing to do with the output from you camera. Of course you can capture a lower resolution image out of the camera (e.g. 3:2 mode, or S size etc). However it will just limit the headroom of how you can use the image, e.g. print large, view on a higher resolution screen, to crop etc.
