Post-screening HBZER

Sun Oct 06, 2019 5:26 pm

Hello,

I'm new on Airliners.net and I've uploaded 2 photos and they have been rejected.

In first this picture for underexposed, quality and distance
https://www.airliners.net/user/photo-co ... to/5686547

Then this picture for underexposed, quality and not just in frame
https://www.airliners.net/user/photo-co ... to/5686543

For the quality It's probably because I've uploaded a reduced size (1887x1258 px instead of 5291x3527px). I've use this format on flickr to avoid a photo theft on social medias and If I've right this size is accepted by airliners.net.

For underexposition I use a scrren correctly calibrated in brightness and color and for me the exposition is globally correct, maybe too lot of shadows on the belly of the A380 ? To increase chance of acceptance I can increase the exposition level.

For the "not just in frame", I think it's because I've cut a wheel on the right side and for this I can't do anything.

Can you tell me how I can improve these pictures ?

Thank you in advance.

Edit : I've forgot, the second picture was rejected too for distance (too close ?) and soft.

The base quality doesn't seem as poor as we often see, but I strongly recommend you to properly read this thread before uploading:

Thank you so much for this link, I will read it carefully. But I don't know how to improve quality, any idea ? Maybe for the moment I want to improve the other points.

The quality isn't super bad and there doesn't seem to be anything wrong with your equipment. The Easyjet looks sharp, but needs post-processing/better in-camera photo taking.
the A380 looks a bit blurry, but that can be expected for such a photo and doesn't necessarily reflect on the quality of your gear.

I've identified two problems. During Take-off or landing Airplanes are a little bit blurry, it's very visible on the nose. I'm using a shutter speed of 1/500 and I'm using a 70-300 in APS-C (105-450 Full Frame equivalent), maybe an higher speed like 1/1000 or 1/2000 can avoid blurry effect ? But I need to decrease depth of field (open to f/5.6 instead of f/9). In a second time, I can use a monopod to increase stability during shooting.

The second problem come from Lightroom exportation, I'm losing a lot of detail and quality. I'm using now only DxO Photolab for development, much better.

I recommend using a faster shutter speed than 1/500th of a second for airplanes taking off or landing especially when using a long focal length. A guideline for shutter speeds in relationship to the focal length is to use the inverse. I.e. if you're using a 300 mm lens, then you need at least a 1/300th sec shutter speed for a hand held shot of a stationary subject. On an APC, I would make that 1/450th. For a subject that is in fast motion, you'd need at least 1/1000th of a second (IMO) to assure no motion blur. As for aperture, I consistently shoot at f/5.6 or wider when the subject is at distance where the depth of field is not that shallow even at long focal lengths. this assumes shooting on a bright sunny day using an ISO of 200.

If you're having blur at the edges (e.g. nose, and/or tail), it could be lens aberration as well. Higher quality lenses tend be sharp across the entire frame.

Hope this helps.

I am able to see the image. Unfortunately, the image is underexposed, low contrast, soft and noisy. Quality is just not there for an a.net acceptance.
