    Back to the drawing board...

    I notice I had Noise Reduction active on camera. (from a previous Via Láctea session..)
    The rest is/was standard
    - ISO 100, RAW, f8..f11
    - Aperture priority mode
    - Spot metter and focus

    In the meantime I've changed lens from zoom 55-200 ... to Fix 50mm
    Changed also software and resize method.
    Resize RAW to TIFF 1280x720 (no compressed) , work on it and then export to jpeg
    I can see an improvement in the jpeg quality... I barely can see the difference between the tiff and jpeg files.

    Changed also the view point, now closer to planes ..
    and strange enough the in flight photos look as good as the stationary ones.

    The hour of the day was different ... just after noon ..and not afternoon.
    Today was a bit hotter , so some heat gaze for distant planes... that's why I move closer to them.

    So here's the results for your comments.

    thanks for your time and help

    Softness and heat haze evident. Also some light editing halos. You can send me one of the RAW files if you'd like me to do a better edit, but if the heat haze is as bad as you say, might not be possible to get a good enough edit for here.

    Thx dlowwa

    Appreciate your feedback. Lots of possible issues/corrections.
    Back to the drawing board then. Lab material is available: Every day 500+ planes land/takeoff here... so, there still a chance I can get a sharp photo

    Thx again for your time and help.

    Well, it looks nothing can be saved here

    Let me try to understand the results

    SOFT could be :
    1) out of focus
    2) not good lens
    3) not good camera
    4) overall bad processing

    COMPRESSION could be:
    1) wrong jpeg compression options
    2) wrong software
    3) bad processsing also

    offcourse also bad photographer skills...

    So it looks I have a potential HW problem and/or a potential SW problem.

    HW just implies a new camera/lens...a no go at this moment.
    SW... could be solved
    Skills... well, who knows with time.

    As such, I need one more favour from you in order to decide my next steps.

    I'm including 3 files
    1) An original 24Mb RAW file. ( I couldn't load this 30Mb RAW file... ).
    So I've converted it to tiff and upload it here : www.flickr.com/photos/ajmm/43030731454
    .. and original 6000x4000 resolution
    2) A croped version in JPG format
    3) ..and a resize/croped versions in JPG format.

    Is there a change you can look at them and see if the original file is good enough....
    ..and therefore what is failling is the resize and or processing work ?

    ..or if the original file isn't good enough and therefore I should focus my hoobies somewhere else

    thanks again for your time help (and) patience

    In this case, it actually helps that you posted the wrong size first. From those images, I can see that they are quite soft as well, and the whole frame, so that means focus error is not the main issue. Camera itself has little to do with sharpness, and since these are not processed, processing is not the issue either. That leaves lens softness as the likely culprit, though the exif has been stripped, so I can't tell if the settings have contributed to the problem.

    The full size images area also highly compressed, so somewhere along the line, either in camera or in processing, you've compressed the files.

    As for the uncropped images you've linked; also somewhat compressed, but not terribly, and still quite soft. Looks like it's a combination of lens softness and slight mis-focus, since the background looks a bit sharper than the aircraft. Try stopping down next time to f/9-10 as this should help reduce the lens & focusing problems. If you're working with RAW files (.nef), then also change your save settings when importing/converting to jpeg to make sure the quality is set at maximum, and that should alleviate the compression issues.

    The newer upload-sized edits look better, but still have issues with color/contrast, and compression.

    Sorry, didn't knew about the size limitation for pre-screening.

    Here's then a subset of them with (hopefully) the correct size 1280x720.
