After writing up my Creativity Challenge #1 post a few days ago, I processed a few more photos shot from exactly the same position in less than an hour, highlighting the amazing changes in colour that occur during dawn (and dusk).
Too often I race around looking for a range of different locations and compositions, particularly when the light is good and the colour hits. These shots demonstrate that at twilight, when the light changes so quickly, it's worth staying where you are and shooting over a period of time.
