In the lower left hand side of the bird photo there is some funky yellow thing going on. I get a lot of pictures of sand or dust, like the beach picture, in them rejected. It seems the inspectors don't really look at the content. Sand is grainy. The 3rd picture, I have no idea.

Ich denke:

Bild 1 (Boot) da sind die Plastikkisten Scharf, der Mann
daneben nicht. (F2,8)???

Bild 2 der Vogel ist zu sehr scharfgezeichnet.

Bild 3 da fehlt die Schärfe (Focus???)

Mit freundlichen Grüßen Knipsersiggi

I think:
Picture 1 (boat) there are the plastic boxes sharp, the man next to not. (F2.8) ???
Picture 2 the bird is too sharp.
Image 3 is missing the sharpness (Focus ???)
Sincerely, Knipsersiggi

Zoom in to 100% on each picture. Does the entire image, especially in the blues and browns, look grainy? Can you see pixelation, grain in the shadows? If so that is noise and for this subject not acceptable. The bird is over-processed, too sharp and that is what caused the noise in that shot.
