Colors

I took some pictures of my daughters room my my K20D with my recently purchased Sigma 18-50 f/2.8 and 2 of her walls are purple and 2 are orange. The orange walls turned out mostly accurate but the purple walls cam out blue.......can anyone help here.......is this just to do with lighting and white balance??? I tried taking different shots at the various white balance settings on the camera..........?????

Thx

Please post a sample.

Without knowing more, its tough to make an accurate assesment. Unless you have a hardware calibrated, high-end computer monitor, the problem may not be in the camera. Same if the printing is not performed on calibrated equipment.

It has to do with the white balance. The camera is thinking that you have a tungsten lighting source and not a purple one.

Also could be a matter of clipping the red channel - it is often necessary to delberately underexpose a little when dealing with highly saturated colors.

Anomalous reflectance

I've had the the very same problem with house interiors.

The tech sheet refers to film but the principle applies equally to digital I'm told by an ex Kodak man.

I had the same issues with my K20D when shooting street lights at night. I noticed that when there was a mixture of different temperatures of colors the AWB would get confused and generate odd colors, esp. in the presence of yellow+red+green. In those situations I'd recommend shooting in RAW
