miscelanous Cave with light from outside (blue) and reflected light from the inside (yellow).

The blue was not visible with the eye. It showed on the picture because the camera had to choose to whitebalans on the light from inside (reflected light) or from the ouside. When I looked through the viewfinder I choose to whitebalans on the reflected light.Image description DCF 1.0Make Minolta Co., Ltd.Model DiMAGE 7Orientation upper leftX resolution 72Y resolution 72Software Ver.2.00eDatetime 2002:01:03 16:31:29YCbCr positioning centeredExposure time 4 sF-number 2.8Exposure program Normal programISO speed ratings 250Date/time original 2002:01:03 16:31:29Date/time digitized 2002:01:03 16:31:29Component config YCbCrBrightness value -5Exposure bias value 0Max. aperture value 3Metering mode PatternLight source UnknownFlash Focal length 7.21 mmColorspace sRGBPixel X dimension 2560Pixel Y dimension 1920
