I am still a newbie and sold my FinePix S3000for a Canon EOS 300D. I am still learning a lot but I am stuck at the moment.

I took a picture of my house with the 18.00-55.00mm lens and with the following settings:

Shutter Speed 1/125 sec
Aperture f/8.0
Iso: 100
Focal Length: 18.0 mm

If you look at the right side of the building you see a blue line and i see that in a lot of pitures i take.

Can Somebody maybe tell me what I am doing wrong?

Thanks - Sean

I loaded the picture into PSP7 and enlarged it. What I see in the circled area is aliasing (or is it anti-aliasing?) It is basically a stair step pattern created because the line is not perfectly vertical. I suspect it would not be noticable in a larger, uncompressed image. Jpeg compression and resizing for the web have probably emphasized the problem.

Thanks for that. When I printed the photos of i couldn't notice it. Here is a crop version of picture. I also forgot to mention that ishot the photoin raw format.

But thanks anyway. I just wanted somebody else's opinion on that.

Thanks A Million

it looks like purple fringing that happens sometimes in photos on the edge of bright areas.

As the earlier comment mentioned, it's probably purple fringing, aka chromatic aberration. I've read comments in reviews that say the 18-55 zoom lens displays more of it than it should. Buy a better lens and it will probably be reduced.
