My Confession: I've read forums but never'd posted any. This is my 1st time. I don't know much about photograhpy.
I'd just bought a Canon Powershot A75 yesterday. While exploring the digital camera, I had a shot which gave an image which is almost completely white with a large patch of purple at the lower bottom corner and a much smaller purple patch at the top middle.
I'm not so much concern about the white image as I think it might be due to the ISO400 setting. When I reduced it to ISO 200, the image was no longer white and it showed up an acceptable image.
I'm concerned about the purple patches that appeared in two places in the image as I think tt might be an indication of a faulty CCD sensor!!!???
If I set the shutter speed to say 1/125, the under-exposed image shows up but still with noticeable purple patch at the bottom right hand corner.
Camera Settings for the white image were as follows:
Shutter Speed : 0.15 sec
Tv Mode (Time-priority Mode; the shutter control mode, I think)
Exposure Compensation = 0
AWB (Automatic White Balance)
[ ] (i.e. Spot Focus)
Superfine S (i.e. 640 x 480 pixels)
Does anyone know what's going on? Is it the CCD Sensor problem? Is it inherent?
