Olympus c7000

I have a problem that I hope someone can solve for me. I just bought this camera to use for taking shots of houses for a real estate guide. The pictures are coming out with swirls and curved lines in the roof and sides of the homes. I have noticed some of the local magazines have actually printed shots of homes with these same distortions. I also noticed the curved lines appear in my Olympus manual on a shot of 2 skyscrapers however the text under the shot addresses lighting differences between the sky and the buildings and ignores the distortion in the buildings. (?!?) Does anyone know what this problem is and how I can fix it? I've tried shots in jpeg, tiff and raw, they appear in all 3 formats.

Any help would be greatly appreciated.

Thanks,
Anita

Why don't you post a sample? This sounds like a problem that Olympus may need to address. Lots of Verticals or horizontals (like siding on a house, or columns and rows of windows on building) can produce strange artifacts in the rendering portion of imaging software. There may be a software update for your camera at the Olympus web site. The techinical term for this phenomena won't come to mind at the moment.

Mosaic compositions (shingles, tiles, lots of regular shaped object in a pattern) also create problems, like curves that are there, etc., as a result of the same algorithimic failure in software. Usually this problem only occurs with compressed images (jpegs) at some stage in the workflow - imaging to final press copy.

I've also seen high contrast (lots of sun and shadow) just play havoc with certain sensors and there's no good cure for those issues.

Post a small photo or a link if you could and maybe someone else will recognize for this Model of Camera what's actually happening. - C
