As a rough guide, the warm color temperature of candlelight is approximately 2000 K (Kelvin). Warm colored light has a low number on the Kelvin scale and cool colored light has a high number. This is the reason that when you take a photo of a snowy scene on an overcast day or under the shade of trees, the snow often appears blue in your photo.Ĭolor temperature is measured on the “Kelvin scale.” While you don’t need to know much (or anything) about the Kelvin scale in order to get the colors right in your photos, having a basic knowledge of it can help you understand the white balance settings on your iPhone. Taking a photo in outdoor shade or in cloudy conditions produces a cool blue color cast, so the colors in your photo will appear cooler (more blue) than normal. So in the photo above, the white walls appear a yellowy orange because of the color cast from the light bulb. While a color cast affects the entire photo, it’s most noticeable in the white parts of the image. Or a scene lit by a household lamp might end up with a warm yellow color cast. So how does color temperature manifest itself in your photos? Well, if you take a photo in candlelight, the resulting image might end up with an orange color cast.
The color temperature of bright midday sun is fairly neutral, whereas the color temperature of sunset is much warmer. Orange is a warm color and blue is a cold color.Ĭandles emit a very warm orange colored light, and tungsten or incandescent bulbs (ordinary household light bulbs) emit a warm yellow colored light.īy contrast, the color of light in shaded areas or on an overcast day is a much cooler blue. The color of light is known as “color temperature.” When we talk about color temperature and color casts we’re referring to the relative “warmness” or “coolness” of a color. Different light sources emit different colored light, and this has an effect on how the colors appear in a photo. When an entire photo is tinted with a certain color, we call this a “color cast.” Color casts are caused by the type of light that you’re shooting in. Have you ever taken a photo with your iPhone where the color doesn’t look quite right? Maybe you’ve ended up with a photo that has an unsightly orange, yellow or blue tint? In this tutorial, you’ll discover how to use white balance to get perfect colors in your iPhone photos.
