These photos pay special attention to the multi-faceted vitality of birds in the 3 phases of spring so that they fulfill the比賽主題：留意春季充滿生機的景像。The 3 phases these photos portray are:
1. Early spring.
2. Mid-spring.
3. Late spring.

The low level cruising shown here is a standard method for this kind of birds to fishing when the river is filled. This bird cruised inches above the water and picked up any fish under the flying routine.

More than 10 years ago, I took a duty of creating e-learning courses. Our survey found that only 40% of our students have had computers. In recent years, the poorest parents in Hong Kong spend their money to buy second hand computers for your children to cope with school works. They spend a few hundred dollars less but those second hand computers are very old and slow. At the same time, the students from the middle class and the wealthy are now buying expensive cameras and bring those expensive cameras back to school for everyday shooting. This series of photos proves that the cheapest digital cameras can produce excellent photos (including excellent photos of flying birds). Hence, the poor students who can only afford a sub-1000 dollars DC should not feel unhappy because these cheap cameras can train them to become professional photographers providing that they try hard to learn photography.
Finally, I would like to thank Rollie for producing such capable camera at such low price that the poorest people around the world can enjoy taking excellent photographs.
