    Thx dlowwa
    Every day a new experience... or should I say : damn ?
    This lit "percentage" just caught me off guard. Imagine that I went purposely for a spot UNDER the plane to take the photo... damn, damn & damn
    thanks for the time and help

    Don't know where to report it... so

    Photo https://www.jetphotos.com/photo/9334436 is incorrectly registered as CS-TOA - A340... where is should be CS-TUA - A330 Neo

    Hi dlowwa

    After some months in this hobby, I thought I had learn a couple of things, but unfortunately I keep having rejections like: center, dark, rotation and even softness.

    My confidence is really low nowadays, I'm convinced I've the best photo in the world.. and then it's rejected. So I'm back again to basics, which means I'll bother you with some reviews, I'm sorry for that..

    Can you please then review these ? thx

    1-2, 4-5 are all poorly centered, and have a couple of soft areas.
    3 is very soft and also compressed

    Thx dlowwa

    Usually I center the image by centering the plane in the central square
    However for this kind of angle (that I usually don't use) ... by centering it, based in the central square ..it doesn't look good, you as just mentioned.
    So what are the rules of engagement for this kind of angles ? center based on "envelope zone" of the plane ? or center based on the mass center of the plane

    Any one of these is ok

    #1 center of mass center
    #2 envelope center
    #3 center based on central square (original photo)

    /rgds
    thx

    Personal preference of course, but if you're hoping to get it accepted here, #2 would be the way to go.

    ok.

    #Personal preference of course,
    ah... there's no personal preferences here... acceptance is the goal

    Hi dlowwa

    I've this photo https://www.jetphotos.com/photo/9336517 , which don't show up in FR.
    Is this because of that specific angle/framing isn't allowed in FR ?

    thx for your time and help

    Hi dlowwa

    Can you give me some guidance on this rejection : https://www.jetphotos.com/viewqueued_b.php?id=7359336

    1) Dark: Is there any practical method to identify a dark photo ? any histogram that shows that ? what's the line between personal preferences and a "scientific approach" ?
    2) Similarly photo :

    This photo was taken
    a) when the planning was in a landing attitude
    b) from a position below the plane
    c) in a 90
    d) in the beginning of the runway
    e) different days, time of the day and backgrounds

    the other which may have been considered as similarly : https://www.jetphotos.com/photo/9269991

    a) was taken when the plane was in a take off attitude
    b) from a position above the plane
    c) in the end of the runway
    d) from a angle behind the plane
    e) different days, time of the day and backgrounds

    what make these photos similarly ?

    You have an empty area on the right side of the histogram : "scientifically" underexposed...




    +1/4 Stop would probably fix it...

    Indeed, the gap on the right edge clearly shows underexposure.

    Same side, same stage of flight. Similar guidelines were updated a few years ago, you might want to review them.

    Thx zomeu, dlowwa. Ah.. finally a "scientific" way to measure/identify darkness. Just great. thx.


    #Same side, same stage of flight. Similar guidelines were updated a few years ago, you might want to review them.

    I've review the rules :

    2.6 Similar

    Means that you have a similar photo already in the database. Please upload only your best photos, try to be creative. Similar refers to:
    - a photo taken from the same sequence the same day e. landing, taxiing, ramp parking or take off
    or
    - same registration, similar angle or composition or same background taken on different dates.
    - Close up views and full or partial views of an a/c taken at the same angle, are generally considered similar.

    If a new upload is of a significantly better quality, we may consider accepting it.

    We will only accept a certain number of cockpit or window shots taken in the same aircraft (normally no more than two).
    #Same side, same stage of flight.
    What I should consider as "same stage of the flight" ?

    One is landing, the other is taking off
    One is accelerating, the other is decelerating
    One is level, the other is 30 up

    In the air vs. on the ground. Both are in the air = similar.

    Thx dlowwa. Putted this way, there's no margin for debate. Reading the guidelines, I would never saw them as restrict as this. But rules are rules and things are what they are.
    thx again for your time and help

    1. soft, centering
    2-5 borderline soft, but no major issues

    Thx dlowwa. Well, it looks , the "soft" plague just land on my photos and I can't get rid of it.
    Can you help me understand it ? is it a HW or SW problem ?
    I'm including an original out off the camera file. is it soft already at origin ?

    thanks for your time and help

    Yeah, that's pretty soft. Still, at nearly 5000pix, you should be able to hide it well enough when sizing down to 1280 or so.

    Here's something I consider decently sharp, straight out of the camera, only cropped to show more of the aircraft:
