Do you want to know How To Photograph Snow and have it come out white?
Why does snow appear blue in photos … and how can you correct it?
We have had a lot of Snow in Ireland over the last week and I have seen a lot of pictures on Facebook / Flickr which have a blue or non-natural snow colour.
This post explains why thBasically, snow reflects a lot of light including the blue colour from the sky and any other lights which may be nearby (i.e. Neon / Yellow Street lights), and this can confuse the sensor in your camera. The DSLR camera will always try to average a photo to 18% gray. Therefore when taking photos of snow, the camera can often under expose the photo resulting in a gray or blue tinge to the photo.
There are certain things you can do on camera. You can shoot the shot with +1 ev or +2 ev exposure compensation as well as shooting RAW (just to allow some further adjustments in PhotoShop later)- use your histogram to check it is correct.
White Balance Correction
You’ve taken this photo and Snow appears Blue … not what you want to see!
By using White Balance Correction you can achieve this in 10 seconds
This is probably the easier way to correct your shot and I normally do it using PhotoShop in order to get the shot I am looking for.
As long as you shot in RAW, you can change the white balance in a program such as PhotoShop (or you can use a basic correction tool in Picassa which does an okay job also). You can select from a list of preset values such as ‘sunshine’, ‘cloudy, ‘tungsten’,’florescent’) or you can use a color-picker tool which is an eye-dropper icon in the white balance settings to pick the snow as your white point. I normally use the eye-dropper tool as it gives you a bit more control.
By selecting the correct White Balance – Snow appears white as it should and you have a great shot
This white balance tool is also excellent for giving you a really good night shot. I will cover this soon in another post about long night exposures.
