True blue

The last Readers Photo Challenge assignment explored the time of day know as the golden hour. This month’s challenge is what’s known as the “blue hour.”

Like the golden hour, the blue hour occurs twice a day, once in the morning and again in the evening. Unlike the golden hour, it happens about an hour before sunrise or just after sunset. It’s in this twilight period that the blue hour happens. All too often photographers, think that when the golden hour is goes away, their picture opportunities go with it. But that’s when the blue hour is just beginning. The sky gradually deepens to a dark royal blue and, in the absence of any artificial light, a blue cast will envelope the scene. That veil of blue can help to give a quiet and somber mood to your pictures.

The blue hour is often useful when shooting cityscapes. Its a time when man-made lights start to come on and because of their inherent warmer colors, provide a nice counter point to the blue of twilight.

This time of year the evening blue hour starts around 8:30p.m., then is done by about 9:30 p.m.. There is a transition time between the golden and blue hours that is also quite beautiful. There will be a fading band of orange on the horizon which transitions to a blue that gets deeper and darker the higher in the sky you go. Eventually, as time ticks by, the sunset will disappear completely and the blue hour will take over.

When shooting during the blue hour the biggest concern is that you will have less light to deal with, so be careful with you exposures. Because the low light can confuse you camera’s auto exposure systems try to use manual. If you’re unsure, just “chimp” it (review the photo on your camera’s monitor) and adjust the exposure accordingly. Also because of the low light situation you’ll probably be dealing with slow shutter speeds and wide-open apertures, which means camera shake and very narrow depth of field (the amount of the photo that’s in focus) will be problems. Try using a tripod to reduce the camera’s shakiness and take time to focus the camera with great care.

So the next time you go out to shoot during the golden hour, stick around a little longer and think blue.
