I was very happy to get some prints on A3 paper for the first time . The picture was taken with my Olympis Omd em5 mkii with the M Zuiko 14-150 mm . I was pretty amazed of the details on the printing. 16 Mpx are more than enough.
The next step will be to do it myself with my modest photo printer Epson Expression Photo XP-960 and using my new monitor ( BenQ BL2420PT, Écran 24 inch, Résolution QHD 2560 x 1440, 100% sRGB, IPS). I have a x-rite i1 display pro calibration device that i will use to calibrate my screen.
