Confused as to why this photo was rejected for "Technical Issue"

@RALPH_L is correct with the underexposure. You want to avoid losing too much contrast, but you need to lighten-up the shadows. At the same time, parts of the picture are in plain sunlight. You lose detail there too.

@George_F is right that the chromatic aberration needs to be addressed. And then you have a high noise level in the shadow areas.

And this something should be edited out:

Hello @zedlyfe , the photo is underexposed. It needs to be sharpened, cropped and the trees and timbers need to be straightened.

I think this composition works better without the sky included and cropped a bit.  I think with the exposure and depth of field issues sorted out, I think this would be a decent image.  I can't comment on the commercial viability though, that's best left to the experts.

I spotted two things that may have led to it not being accepted on technical grounds.

The front part of the bridge wasn't in focus, I'm guessing because it was shot at f/4 at 48mm and the depth of field wasn't large enough to cover the entire bridge.  The dark areas of the bridge were underexposed enough that there wasn't much shadow detail in there and it introduced a lot of noise when pulling up those shadows.

There were some chromatic abberations in the trees at the top of the photo.

I also think the photo would benefit from some sharpening when viewing at 50%-100%.

I hope that helps!

Reading all the other posts here, looks like "Technical Issue" could also be synonomous with "this is a bad photo." However, I don't think thats the case with this one.
