Printing Dpi vs MP count
In the constant hunt for higher megapixel cameras and high quality prints (suitable for a photography exhibition in my case) at what point is do we just get on with doing what we do best, that is taking photos I like many photographers want good quality prints but being new to enlarging photos beyond 30x40cm Im trying to establish when is enough MP really ..enough.
When printing an image onto high quality photo paper using a printer such as (example only) Epson Stylus Pro 9890 (or similar) at what size does the megapixel count become more or less important. My images consist of cityscape and landscape (day & night) with the occasional portrait so detail is important, but at what point is the printer unable to produce more detail from a given file?
Print size example (100cm w x approx 70cm h)
100cm wide print using a 24MP DX camera eg D7100
100cm wide print using a 24MP FX camera eg D600
100cm wide print using a 36MP FX camera eg D800
