I can see maybe stepping back on the contrast a little bit not too sure on the horizon issues. It's a tight shot but looking in the background everything is pretty vertical. Maybe a tad clockwise?

Thanks!

Yes, a tad clockwise. Make the nearest corner of the cab and the third vertical bar from the right in the cantilever vertical.

Re contrast, increase exposure and your contrast issues will go away. Same problem as here a day or two ago, the one where Mitch showed the screen grab with the histogram. The histogram is your friend.

Turn it clockwise till the signal mast is plumb, kick up the contrast and darken it a tad.

You might have to adjust the saturation down a bit too.

Next, you need to use the distortion tool to pull the upper right corner up until the horizontal part of the signal is more parallel with the top of the frame, and then pull then entire shot up so the engine looks right again (pulling on the corner will compress the image slightly).

Sorry, Billy Bob, but that is wrong. For this shot, level with something in the middle of the image first, and then correct distortion. The right side of the image still looks funky with the way you did it. Unless this is a tighter crop of a much larger view, he's going to lose a lot with the proper distortion correction.

You're right, that is probably the better way to do it, but good luck explaining what part of the background to use and why.

And he is going to loose a bunch either way you do it because he cropped it so close.

That is something I figured out on the night shoot of the street cars last week - if you are shooting up close with a wide angle, back out the crop and give yourself plenty of room to pull the corners.

The composition out of the camera looks funky, but when you process it, the dead space goes away by correcting for the optic distortion.

He could have used that knowledge here, to keep the tops of the signals in the frame.

Course, if he is good with PhotoShop, he can fill in the missing parts with the clone tool to keep the sign tops.

Or accept the presence of distortion in a wide angle shot and follow the sage advice in post #2 ...

He can use the verticals in the middle of the signal bridge to level it and then tweak the verticals on the sides from there.

How much cropping was done to this image? Becuse my guess is that if the other issues are fixed, that the next rejection will be for the shot being way too tight.

I would agree with that if the distortion was more balanced through out the image, but I only see it on the signal mast..

My first question is the same as Joe's. How tight is the original frame? Do you have a little more to work with?

The contrast is the easy part. Leveling will be nasty but can be done.

The distortion fix is going to be the toughy.

Cool aphorism, Bro.

But I do not feel we're asking for perfection, only adequacy.

As far as "Art" is concerned, I concur.

However, not in this instance.

Hey guys thanks for all of the responses! This is as backed-out as things can get as I shot it extremely tight to begin with! The bridge I was standing on is tucked right up to the signals and there is a harsh tree line to the left, which unfortunately was the lit side. I'll try playing around with the leveling and distortion and see what I can come up with based on everyone's recommendations. Hopefully not too much photo surgery will be required to retain the full signal bridge.

Worse comes to worst that signal bridge isn't going anywhere and I can always try again!

Thanks again guys!

Davis

Looks like you need a wider lens.

Use a wider lens.

What lens did you use and at what mm?

EXIF shows 18mm on a D40, so likely the 18mm was the limiting factor.

Janusz has got it! 18 on a D40.

Talking

Is a D40 a full frame camera, or a cropped sensor?

Because if the sensor is less than full frame, the actual focal length is going to be much more than 18 mm.

Holl, my statement that "likely 18mm was the limiting factor" was intended to convey that this is cropped sensor, as the common kit lens for those goes down to 18. Not as clearly as I would have liked.

Whoa chief, not questioning the accuracy of your explanation.

I am unfamiliar with NIKON equipment and I doubt the OP knows about the cropping issue which is why I brought it up.
