The occasional glowing orange sky with forenoon sun commands attention and stimulates desire to take a shot. There are certain atmospheric conditions during winter when the sun remains in the orange sky for a long time to become a subject of photography and experimentation.
Exposure can be challenging for taking picture of the orange sky sun. Try to under-expose by good 2-3 stops to avoid over-exposure. Protect your eyes and the camera when photographing the sun.
It’s also important that while photographing the sun, you should not to stare at it too long to protect your camera, sensors and the eyes.
If your digital camera has a sunrise or sunset scene mode, it is so much the better. Otherwise, select a small aperture for maximizing your depth-of-field. Set your camera at the lowest available.
Use a tripod or a firm rest with either a timed shutter release or a shutter release cable. This will prevent blur resulting from camera shake.
Since the sun is quiet above the horizon in the forenoon try to compose the orange sun by including some surrounding elements in the picture.
