    are the strong defined black letters the reason of the overprocessing ?
    or are the strong primary colors the reason ?
    No, same reason as before - editing halos visible around fuselage. Much easier to see equalized:

    #1 - strong editing halos Click image for larger version.

    ah... no wonder I coudln't identify/notice : (halos, overprocessing) ... I was trying to see them at "naked eye" in the original photo.
    While this equalized view is where I should be using to look for the problem.

    So, for the other issues : (borderline, contrast, compression ) is there any other view/tool/report that can/should be used to identify them ?
    Is there any automated workflow to analyze the quality of a photo ?

    thx

    No, the problem is easy to see with the naked eye. I posted the equalized versions simply because you seemed to be having issues seeing them yourself, or even understanding what I was talking about.

    #I posted the equalized versions simply because you seemed to be having issues seeing them yourself, or even understanding what I was talking about.
    You are 100% correct on both

    There are halos and halos.... and I coudln't see these "small" color depressions in the sky...
    Then the word "overprocessed" just lead me to look at oversharpen ...

    I need now a training course on the Airport's XRay security scanner system...

    So let's see if I can start to use the equalize function to post acceptable photos.

    1) this clearly shows halos and the borderline problems ..correct ?
    2) in this case the borderline is the problem ... correct ?
    3,4,5 ) these photos looks ok, regarding halos and borderline.. correct ?

    thx again for your time and patience... (I hope) I'll get there one of these days

    Only the first one is really obvious, but again, the equalized versions are not what will be screened. The halos need to be visible on the uploaded version to actually be an issue.

    #The halos need to be visible on the uploaded version to actually be an issue.
    I understand, my problem is realy to see them at naked eye... maybe now with the help of the equalized function I can train the eye a bit.
    However, I believe that the best solution, is to not create them to start with.... so I'm applying a (halos) bullet proof processing... that does not create halos

    So let's see if I have learned anything.

    Can you please review these ? thx

    Hi dlowwa
    continuing my dawn series, can you please have a look at these ?
    and additional, can you comment on, if I should continue on this path ?
    shooting in low light is a challenge for sure... but the end result isn't always understood or even make any sense.
    If isn't a specially situation then a shoot like the 1) with plenty of light is always prefered , right ?

    thanks again for your time and help

    Whatever your personal preference is. I like soft evening light (as you can tell by the majority of my uploads during the summer months), but different people have different preferences.

    Thx dlowwa

    Your photos from Vancouver, looks great. The shot angle (almost in front ) and the angle of the sun, does create a very clear and live photo.
    I'm also assuming that the evening light in vancouver isn't as warm/yellish than in a warm climate.
    Anyway, a good photo is always a good photo, independent of geo coordinates.

    #but different people have different preferences.
    For sure, I may say that I like brigther and strong colors... but I'm not even there for the moment.
    For the moment I'm just trying to test things: spots places, angles, lights, distances... lens

    Today, for instance... photos 1,2 were shot in the morning ... and 3,4,5 where taken at dawn ... 5) was just 10 minutes before sunset.
    For 5) I tried to "remove/correct" a litle bit the yellish on it.. and I've change the ISO from 100 to 200 in order to keep f/8 & 800/sec

    Just because, yesterday I've missed the same due :
    1) to close, the 50mm lens cut it..
    2) to soft : f/6.3 and 250/sec

    as such can you please review them ?

    thanks again for your time and help

    ah.. living in a sunshine country, I thing there's no point in keep taken darken photos.
    But planes keep arriving at strange hours... so . And in this particularly situation, I believe I've taken a sequence of 5 sharpen photos, so if they can be recouverable.... the better,

    But more than one single photo, I'm struggling a bit with this evening light & dark results. If it's almost night... there's no point in hidden/faking it right?

    Image 5) (unedited) we see that it's almost sunset.... and that the plane receive the total light still available. Is that ok at it is ?
    While the 4 other images have then receive "some ligth processing"...

    As such can you help me here undertstanding the rules of engagement for low light ?

    Are then any of these acceptable ?

    thanks again for your time and help

    Exposure looks fine on this set. They are all the same sequence, so select just one if you would like more feedback.

    #Exposure looks fine on this set
    Ok.

    #They are all the same sequence, so select just one if you would like more feedback.

    I'll select the last one but with a twist ... opening another door for experiments : closeups/crop photos.

    Can you please comment on these ? thx
