I lov ethis one the best - your horizon is straight, and the branch frames it really nicely :)

Perfect - 10/10

It took a little work with Photoshop Elements to get that horizon straight, plus shooting at 45mm with a 17-70 lens There's a good deal of barrel distortion at the widest 17mm setting, and that's why the horizons look curved in many of the other shots.

I realised the distortion would be coming frm the 17mm - there is a way to fix this though i'll look it up in my photoshop book and le tyou know - and see if you can find the smae thing in elements.

Getting those horizons straight can be a right royal pain in the ass sometimes. No matter how hard I try to get them straight in the camera, my shots are ALWAYS sloped upwards from left to right. Some are really bad.

I'm wondering if it's something to do with my balance or lack of it.

I really did like the framing on this one though - really made it.

I have some other tips for you which I'll pop in an email to you tomorrow when Im more awake :)

Cheers
Robyn

Sometimes, I understand, the sensor in the camera can be ever so slightly tilted when it is installed. Some fellow Pentax users have returned their cameras to Pentax for adjustment for this reason.

One way to tell is to mount the camera on a tripod using a level to make sure it's straight, then photograph the horizon. If there's a tilt (not distortion) then the problem is likely in the camera.

Of course, sometimes just pressing the shutter button causes the camera to tilt noticeably. Using a remote release fixes this. (But who takes grabshots with a remote?)

Later. I just looked at Photoshop Elements, and it has a nifty "Correct Camera Distortion" filter that I never noticed, for my attention was so intent on other features of the program.

I'll give it a go with all the sunset photos on this blog.
