Firstly, I'm guessing this refers to taking pics of buildings, and around the edges of the picture, the buildings appear to "lean" inwards. Kinda like this that I took a few weeks ago

I'm guessing this is caused due to the focal length being to low/at the lowest setting (is that the correct term?) The pic above was taken using a standard 18-55mm Nikon lens at a Focal Length of 18mm.

How is this corrected? Would I be right in assuming a Wide Angled lens would be more suited?

I'm not a pro, but keen to learn. I was hoping to have purchased a Wide Angled lens before our trip to the states, but didn't have the funds available.
 
Apply the lens profile in Lightroom is the easiest way to improve matters I know of.;)
 
Thanks. I need to use LR more, I do my editing in PS as I've used it for graphics etc for about 10 years.
 
you should have purchased your camera gear in the usa a lot cheaper than the uk
i think a tilt shift lens stops this type of distortion
 
Gimp these days and Painshop Pro for many years before it. However, for RAW editing LR wins.
 
holty: I bought enough over there, including 2 watches for me, and some Beats by Dre Studio 2

Seahorse: I remember the days of Gimp many moons ago - will definately give LR a try for RAW editing then - afterall, I have access to the full Adobe CC Suite at work, so need to make use of it ;)
 
buy your beats earphones in turkey for £7:50 pr best copies in the world and fantastic quality you can't tell the differance with the real ones
i normally bring some back and sell on make a small fortune
 
The buildings leaning inwards is more vertical perspective distortion than lens distortion.

But I think I see a slight downwards bowing of the bridge beams which is more a lens distortion.

LR can sort both of these with a single click.

Nikon software like view nx2 would fix the bridge beams but can't do vertical perspective distortion correction.

Any corrections like this will rob some pixels so always worth shooting wider than you think you need to.

Thank you - I didn't realise that this could be fixed post production. I thought it was something that would require a different lens

What exactly causes perspective distortion?

Obviously not too concerned with reproduction if you are using Beats, tbh, not exactly audiophile nirvana from what I read.
 
Not having the camera looking straight at the subject.

Looking up at a building from the base will cause it to taper in towards the top.

Can correct in PS too under filter =} lens corrections
 
If you are used to Photoshop then as above Lens Correction filter, or if shooting in RAW adjust it in Adobe Camera Raw :)
 
When you load your RAW file into PS, doesn't it first open in the ACR window to allow you to make initial adjustments before you actually open in the PS screen?
 
Yes it does. Wasn't sure if it was that initial loading programme you was referring to.

Thanks again
 
In some situations you wouldn't want to fully remove it anyway, the eye expects to see a tall building tapering when you look up at it for example.
The one above isn't really negatively impacted but can see why you might want to remove it. I think the inward lean almost accentuates the tallness in a way.
