Hi Olivier,

I think the first picture is not able to get accepted here even with more sharpening. The back of the fuselage is way to blurry and the front of the fuselage is also not very sharp.

In my opinion the second picture could be accepted if you sharpen a bit. It depends on your editing program but you can sharpen a picture with nearly every editing program.

What apature have you used?
Both look to me if it is way to open, esspecialy on the second picture where the inner left engine is sharp and the pic becomes softer outside.

Dear Screeners!

I have a rejected photo on the following link: https://www.jetphotos.com/viewqueued_b.php?id=6152447
Really sorry, but I don't understand the second opinion. What does it mean : JPG compression artefacts? What can I do in the future to avoid this problem?
