  • Not a screener, also not very sure, but I'd say if you are not so confident about your own luck (like me myself), then just give up any photo taken in weather conditions without direct sunlight. But anyway this is worth trying. In my opinion maybe a brighter one with this contrast would seem better, but please notice that I don't have much experience either. Just a reference for you. Also waiting for a screener.
    Regards!...

  • Hello! I wonder if these ones are acceptable or fixable. If there's contrast issue, how should I fix? Thanks!...

    Not a sceener, but I would say:

    1.The photo is badly compressed, leading to the poor quality. Not sure what software you are using to process photos, but I recommend Photoshop, choosing the highest quality when re-saving as a JPG.
    2.The vignette is caused by your lens generally. When using a big aperture (e.g. F2., or using the long side (200mm in your case) of a lens which is not SO good, this would happen. You could use PS to reduce them, but the easiest way to avoid it is to use a smaller aperture (F8 or so), a smaller frame (APS-C instead of Full) and a shorter focal lenth initially when you are taking a photo.
    3.Not knowing your particular case, but please remember to choose 'military' and 'helicopter' while uploading.

    Hope the above would help. Regards.

    I guess I will use another runway like this.
    Also, for the two museum planes, I'm not sure if they could be accepted, as they were taken in 2013(a long time ago isn't it). And if possible, can they be regarded as hot? I had some difficulty determining the latter's reg in the database....

  • Indeed! I've got a 70-200 already, and I often need F2.8, so I'm not considering 24-105 right now.
    As for the brand, I heard that SIGMA produces sharper photos than TAMRON, not knowing if it's true. Do you have any ideas?
    Thanks for your reply!...

  • Well I guess this is a common case. It only appears on the photo page. As you can see, in your profile you don't really have one badge like this. Many 'Air Force 1' badge are 'awarded' to those that don't have a reg. So just let it stay there

  • Well indeed I'm planning for nearby photographs, like on the ramp when I'm taking a flight, or for an airport overview. I know that this would not be so popular in this field, so just having a try. lol
    Anyway thank you very much for your attention and reply. I will try other photography forums....

    How to choose a 24-70 lens?

    Hi there,

    Recently I have been considering to get a 24-70mm or so. As I don't have much money, I couldn't get one NIKKOR (which costs nearly 14 thousand CNY). Now I have no idea about which one is better, TAMRON or SIGMA. So could you give me some shopping advice? Any reply would be appreciated.

    Thanks!

  • Okay, I've tried to have the small prop fixed, like this:

    Also, I have no idea if the runway photo could be fixed. Hope you could tell me if it should be given up.
    Thanks!...

  • It's getting a bit tricky...
    I've changed to another, for which I made the right edge of the central beam exactly straight. I guess this would be better.
    For the prop I don't know whether the contrast is too much or too little, but anyway I had a try.
    Also, would there be any possibility for this runway photo to be accepted?
    Regards!...

  • I thoought this was just what I did lol
    Anyway I've added some CW rotation, having this one. Would you mind giving some opinions?
    The another was formally rejected due to underexposed. I've also adjusted. Hope you could also see if this could work.
    By the way, may I bother you to help find the S/N of the latter (B-103A)? Th einformation website which we Chinese could access was broken days ago.
    Thanks!...

  • Well... If so, how can I tell that the horizon is leveled when there isn't any line matching? After all, one line is matching the grids in my photo right now.
    Also, this is exactly what my drone has originally captured. If you've ever had a DJI drone you would know that it would level the picture automatically.
    No offense, appreciative for your reply as well, but I still think this is correct. So may I ask you how to judge the horizon please? Thanks!...

  • Hello! I wonder if this is wrongly rejected. https://www.jetphotos.com/viewqueued_b.php?id=10603278
    You can see that the focal lenth is very short (24mm or so), which leads to the lines on the left qnd right side being not vertical. However, the one in the middle, next to the prop, is exactly vertical. So could anyone reconsider this rejection, or give me some suggestions on adjusting the horizon in situations like this?
    Thanks!
