Traditionally, you probably think of using color gels to change the hue of your subjects or to add a splash of color to a backdrop, but with this clever technique, you can use color gels to change the color of the sky. This great video will show you the theory behind the technique and how to change the sky to whatever color you please.
Coming to you from MagMod, this excellent video will show you how you can change the color of the sky using color gels. It is quite a neat technique. Normally, we use color gels to change the color of our subjects or to add interest to a background or the like. However, in this case, the idea is to light your subjects with the gel. This will change the color of them, of course. But then, you will use your camera's white balance to bring your subjects back to their natural color. This will consequently shift the color of the sky away from its true hue. It is a very neat way to either add a bit of interest or to go for a really adventurous look. Check out the video above for the full rundown.
