I have took the above photo many times but have not found a way to be able to get a correct horizon without the bollards looking out. Or getting the bollards straight in photo and then getting an uneven horizon. Can anyone offer a soplution please.

It's known in the trade as 'perspective'.
You could try expanding the right hand side of the photograph.

It's not about what kit I've got, its about having the knowledge to use it to maximum potential.

This sort of thing is quite common and usually the result of using a wide angle lens at an off-square angle, ie., pointing up or pointing down. As a consequence you will never line up the two parts of the image. The only solution is to judge by eye what looks right, even though something may well be out of true.

Don't forget that lots of modern zoom lenses are not rectilinear either, so they bend straight lines, especially near the edges.

A possible solution is to use Photoshop Transform>Distort to "correct" the image as you seee fit.
Best regards, John

Or you could "stitch" the two halves together!

Lightroom's Horizontal perspective control will sort that easily.

Although to be honest why should the bollards be horizontal? The second pic looks fine to me.

Thanks guys for the feed back this shot has frustrated me many times. I dont have a copy of photoshop yet but may be able to work something out in Serif.

suggest you shoot it with the 10-17 fisheye.
Fired many shots. Didn't kill anything.

Have you tried shooting from further along the path (to the right) and making sure the camera is perpendicular to the street. Other than that a bit of skew should sort it out. I think Serif has a skew function, or you could try freeware like GIMP. (Why buy software these days when people make it available for free!)

I just had a play, and by using the free transform and distort functions in PSE 8 it took about 2mins to do.

Sorry that I'm a little late coming in on this but would like to assure you that Serif (presumably a version of PhotoPlus) is well up to the job. I had a quick play last night with PhotoPlus X3 and following technique worked well

1) Open image
2) Create duplicate layer
3) Add a layer mask to this layer
4) Select the new layer
5) Activate "mesh warp" tool and pull the bottom corners of the image very slightly to the left until the bollards and house are vertical
6) Make background layer invisible by clicking "eye" icon
7) Select black as the foreground painting colour and paint out everything in the image that you want to to remain unaltered, making it transparent. I erased everything down to the top of the house.
8 ) Click the "eye" again to make the original layer visible.

Job done. The advantage of using layers is that this leaves the original image unaltered and nothing's lost if you mess up.

Hope this helps

You could also try http://pixlr.com which is free, online, and pretty impressive!
