Rejected for quality issues. Experienced contributors advice welcomed.

SAM is missing blacks according to the histogram:

All the other pictures are underexposed.

All pictures are missing detail and are full of artefacts, like missing detail, washed out colours, sharpening artefacts, remaining noise artefacts, because of the ineffective noise suppression, compression artefacts.

All in all, the issues are typical for small sensor cameras. Even that your camera does not exactly fit in the category of the high resolution, small sensor phone cameras. If possible, shoot raw and edit carefully and try to avoid difficult light situations and your pictures may get usable.

IMG_4171-4172_pano_pk.jpg - no detail in the shadows and noisy sky

crookedslide_IMG_6706_pk.jpg - zoom in between 100-200% and you'll see that there is a lack of detail and soft focus in the tree line

SAM_1757_water_pk.jpg - soft focus throughout 

Hi @Peter5E6F,

The first file is underexposed and with chromatic noise.

The second file is also underexposed and details are lost.

The third photo is underexposed.

The fourth photo is underexposed and with chromatic noise.

You can find some beneficial tip at this link that will help you identify most issues.

Best wishes

Underexposed, lack of sufficient detail.  Unfortunately, none of these would produce high quality prints.
