I tried out some of the tips I have read in the Digital Photography Book (Vol 1) by Scott Kelby. The best tip was to shoot the flowers from flower level, rather than down onto the flowers. You get much more interesting photos then. I had the benefit of an overcast (rainy) day on the first day we went which made the light nice and soft. And because of the rain, the next day we went, the flowers had little droplets of water on them. I was excited to see that these photos turned out so well.
I will post some more photos of our trip soon :-)
