I took this image at a local museum - the same one the teacup photo came from.  I thought this hallway was pretty interesting, so took a shot.

 

D5500

18-55mm lens @ 18mm

1/30 sec@ f/8.0

ISO 360

 

 

I handheld my camera for this shot.  The original was a little tilted, so I had to rotate it a bit, but while the bricks in the floor seem straight, the ceiling tiles look tilted, and I'm not sure what the reason might be, or what I can do about it.  This is an HDR image I created from bracketed shots - I'm not sure if that would have any effect on that.  I also have used the lens profile in Lightroom.

 

I guess I have a couple of questions:

  -What causes the tilting ceiling but straight floor?

  -How is the composition?

  -What could I have done to improve the image(both with the camera and post processing)?

 

I realized when I got home and started looking at the image that I was not centered in the hallway, but instead was off center to the left.  I did try to crop to adjust for that, but there is clearly only so much I could do in those regards, unless I do some complicated(beyond my capabilities to look good) transformations in PS.

 

Thanks for looking!

The reason for the converging lines in the ceiling and floor is keystoning because you were not centered. It is the same effect that makes a building look like it is leaning back when you tilt the camera so the sensor plane is no longer perpendicular to the z-axis. It is corrected the same way in LR or PS, only on the other axis.

I will have to explore that functionality. Is it lens correction I'm looking for in LR or is it called something else?

Thanks.

I don't know what the panel is called in an english install. It is the one below lens correction.

Check out the editing exercise from last week (I think). I have a screenshot of this tab showing how to use the "Guided" method to correct this.

You are right, it was last week. It is here. The panel is called Transform.
