Perspective distortion..

Is there anything I can do to correct the vertical distortion at the rear tower?

I've used the distortion and correction tools in LR but this then puts the front tower out.

thanks

Something in Photoshop? I forget what it's called. I'm sure there's something like free transform that gives you a grid to manipulate how you'd need to.

Thanks I found this after what you suggested http://www.photoshopessentials.com/basics/free-transform/

Three are 2 ways.
The best, but most expensive so least used approach, is to buy a perspective correcting lens. Nikon sells these as PC lenses, canon as TS. This way you make the correction in the lens and so the sensor records the maximum detail.

The most commonly used approach is just to,use the perspective correction and distortion controls in light room or photoshop. It works well but does mean your image is stretched a little reducing detail and enlarging image defects like chromatic aberration. I suggest you use this but if architecture (or landscapes) is really something you get into then look at buying a PC lens.

I will do. Thanks

Certainly a lot cheaper. On a cropped sensor, that going to pan out 38mm :/

You could try the DXO Viewpoint software.
It is specifically for perspective issues. I've used it once or twice and it does seem to have more control than LR tools.

There is a demo version.

I tried this, any better?

Only problem is that the top of the tower is nearer the edge now..

yep will give that ago this weekend.. it just needs a bit of breathing space at the top.

How does the image look otherwise? I'm looking at including in my LRPS panel.
