106 — White balance and why snow is blue




Photography.ca show

Summary: Photography podcast #106 discusses the often confusing topic of white balance and why sometimes the camera screws up our images like giving us blue snow. Correcting this is really easy and it just requires a bit of understanding of what is going on in the background.  In a very tight oversimplified nutshell, when we see something that has colour, it has that colour due to the colour temperature of the light source illuminating it. Light a candle in a dark room and look at a white baseball; it will look orange. The same thing happens with white snow that looks bluish under cloudy overcast conditions because cloudy light is bluish. Our eyes might not notice the blue because our brain compensates for the cast because it "knows" that snow is white, but the camera often gets it wrong. In this podcast we talk about white balance, automatic white balance, the white balance presets that your camera comes with and setting a custom white balance. If you've ever wanted to improve the colour accuracy of your images, this photo podcast offers up some fast tips.     If your image has a colour cast, to neutralize it, you add the OPPOSITE colour of the cast.    Links /resources mentioned in this podcast: Spinrite - To recover crashed hard drives Allan Levene is running for congress!
