.., photography is like "eating the rice given by the sky", especially for landscape & scenery shooting.. it meant that the nature conditions can affect the outcome of photos greatly.. Even if u shoot at different timing at one location ..the color & lighting can be very different..of course, we must be there at the right time & perhaps ..right season too..:).. if the sunlight is too strong, we can use filters or some other method to reduce it..then the sky color will be better..:)..
Remarks; hehe.. I am in Indonesia now..I am not able to type in chinese using this pc now..
If got time..I will share the sunrise i shoot at Cambodia.. there are 4 colours changing.. however, the camera i used that time was a fool camera less than SGD60...
