Quality problems

7. Blurry, very noisy - you would have needed to use a tripod, wide aperture and low ISO to shoot this scene effectively 

8. Same as above and hotel name needs to be removed 

9. Same as no. 7 and boat name needs to be removed 

10. Noise and blur, leaning verticals and many blownout spots. You would have needed to shoot bracketed images and blend them to avoid those blownout areas.

There are many pictures and the reason is probably similar. Please restrict your uploads to one to three pictures.

Nice night views, and I would not qualify the images as under exposed, either the contrary: Some seem to be overexposed. The pictures have an extremely high noise level, due to the high ISO (for such a camera). You need to pay attention to business names and other identifiable items.

5.1 Overexposed, noise, multiple IP violations: ship names, business logos.

3: over exposure, noise, not very sharp, colour clipping

1.4: Noise, blown out highlights, IP issues.

5: You have several IP related issues: ship names, business logos or similar… Noise is the main technical issue, together with complete blown out areas.

6.1: very noisy. (at 100%)

ISO 1130 is for your Drone too much. 

Photo 4.jpg needs sharpening. The shadows are underexposed and the highlights are overexposed. The sky is noisy. There may also be model release problems if the persons are identifiable when the photo is made brighter.

Photo 5.1.jpg The shadows are underexposed and the highlights are overexposed. The sky is noisy. There must be property releases for all boat identifications or they need to be removed.

Hi,

my guess would be underexposed and blurry.
Also take a look at these infos
