1. soft, contrast, motive. not much aircraft visible.
2. dark, contrast, horizon

Thanks for the answer. Are these problems fixable? I could use the Adobe photoshop or lightroom to fix them. I am worried of the first photo because part of the flaps are cropped.

Contrast, compression, cropping/ratio.

One more question, is this a dust spot? If not what is it?

No idea what you're looking at, but in any case it's your photo so you should know better than anyone else.

Just a few general editing queries,

A. How to spot compression problems and how to fix them ?

B. how to spot noise in photos and how to fix them?

Thanks

Without trying to be flippant, just looking at the image. Noise is obvious. 'Compression' at JP can mean various things, from actual compression (loss of detail because of small file size), to banding in the sky due to fine color gradients not being rendered well when converting to jpeg, to pixel smearing from small sensors/too much NR.

Would this remove compression? And, I do not get the crop/ration part considering its 16:9 ration aspect
Thanks.

Not sure what you mean by 'remove compression'. Compression can't be removed, only avoided in the first place.

290kb seems quite small for a 1280pix image.

This is a 1280pix image, and even with blue sky only as a background, the original file is 635kb - significantly more than 290kb.

This one is 1600pix, and 1.2mb. At 1280pix it's still 877kb

Compression is happening somewhere along the line in your processing.
