So I took this picture the other night from behind my house and about 30 meters up. Overall I am very happy with quality of images thus far. I had a Polarpro ND 16 filter shot at f2.8 1/25 s and ISO 190. Cropped, tweaked saturation, noise, sharpen color and exposure levels. Probably not suitable for professional uses but I did not buy a professional drone. Have you been happy with quality of your shots on the P4?
