It is wonderful to me that when one finds the "perfect storm" how it changes and can give you many, many different photo opportunities that differ greatly from each other if one just waits awhile.
Especially at "magic time" AKA: sunset.
With the rapidly changing lighting conditions, more details and wonderful hues appear.
As the sky grew darker, I put my camera on a tripod, adjusted the exposure and kept shooting, even though my camera was telling me that the light was gone.
By just lengthening the exposure time ( taking the camera off auto) I'm able to trick the camera into thinking there is more light than there is. Keep in mind though, this does have the tendency to increase noise or grain in the photo
However, if you know your PhotoShop filters you can reduce the noise to something acceptable.
See photo below as an example of how even though the Sun was practically gone, you can still shoot and get beautiful results.
Don't be afraid to take your camera off AUTO!
