How to determine if an image is a night shot/sunrise/sunset?

[AaroS]

How can I accurately determine when there is enough of the orange-red glow and when there is not? I don't wanna get rejections that could have been fixed with literally one click of the mouse.

Thanks!

Better forget about the color aspect. Keep an eye for long shadows and fuselages very well lit from top to bottom, without a shadowy half. Also sometimes very well lit main landing gear. All the above indicate a sun positioned adequately low in the horizon.

Thanks! I understand what you are saying but I'm not sure if long shadows and well lit fuselages apply to all images.

For example this image

It was confirmed as a night shot by a screener but I don't think the shadows are that long nor do I think the landing gear is well lit. The fusalage also has this clear darker area.

The screener is more than correct.

Long shadows: obviously there. Shadows are almost horizontal. Even the winglet shows its shadow on the fuselage. Α "long shadow" is practically a shadow deployed more horizontally than vertically, below the wing and tail.
Main landing gear: obviously well lit. You can even see clearly the "inner" wheel.
Fuselage shadows: only at the belly, not at the sides.

Agreed. ……..BUT……

When I was a screener, in the absence of any other reasons to reject I would have ticked nightshot, told the photographer what I had done and why and accepted the image. That’s good business practice. It puts a perfectly acceptable image into the database, keeps a user happy, and teaches that user a little lesson to be acted upon next time around.

This image falls smack on the “is it….isn’t it” line when deciding on night shot and as such deserves some leeway and help.
