Hi guys,
As you will see in the pic below the vertical lines of the
building are distorted. I'm very inexperienced and am still just using auto with my Pro1. Any tips you can offer to sort this out would be much appreciated:)

It just looks like typical lense distortion to me, put it on the 1st zoom setting and take it again :) ...

Distortion come mainly from view point. not the lens.

If you point the camera even a little upwards you will get converging verticals (as they call it).
You have two choices ...
One... hold the camera exactly level. ( dont point it up)
Two...Correct it later in Photoshop or other programme.

This is something we all have to face up to.

If you like I can correct the verticals in your picture and post the result.

I think there is a lense correction plugin built into Photoshop ! ...

I have corrected the verticals brightened it a little and added a bit of sharpening.
I have not corrected for lens distortion as I dont have the camera data for this.
I usually use a PTLens plug in in photoshop for that..
Though as I thought it has very little lens distortion.

Wow, that looks heaps better Terry. Thanks to both of you for your helo :)
It's no problem to take more pix of the church as it's just up the road.
Can you explain a bit about the plug ins you both mention please.

If this info helps, I have Photoshop Elements 2 on the pc but have not used it as PhotoImpression has fulfilled my needs Ok up till now.

I have not used photoshop elements 2 as I use photoshop CS2.

I am not sure if the PTLens will work with it or not but you can find it here
http://www.epaperpress.com/ptlens/
But you can use it as a stand alone programme.it is very easy to use.
(I have checked on the site and they do a set of profiles for the pro1, which do the job automatically.)

It will not correct for converging verticles you need to use photoshop for that.In CS2 you do the following. may be the same in elements)
select the picture( control+A)
Edit...Transform...Perspective.

You can then pull the sides to correct the perspective

Sometimes the distortion is not equal, then you can go...
Edit... Transform... Distort

This lets you pull all sides unequally to sort things out ( I used that on your picture.)

It is worth spending time on learning photoshop, there are some good books giving useful tutorials. with out some guidance it can be all a bit much.

Enjoy your photography

it is not one I would use as it is global rather then specific to an actual camera lens combination.

PTLens take account of the variation of distortion over the whole field and at every Zoom setting, from the exif data, quite automatically.
It can also correct for colour fringing and vignetting caused by the lens.
