In flower photography it often pays to "keep it simple". Flowers lend themselves very well indeed to a simple, minimalistic image which highlights their sheer beauty and gentleness.
From a flower photography point of view you tend to find that that the best images are those that are either i) wild and random - a multitude of flowers and colours with sparkles in the air from pollen and seeds blowing in the wind, with sun rays and a sense of glorious abundance or ii) those that are plain and simple - little of no distracting factors, a limited colour palette, showing just a small part of a flower, gentle, subtle - beautiful.
"Keeping it simple" is quite fun. You often need to experiment with your photography, taking images closer than might seem right, taking images from unusual angles etc. Sometime it will work, sometimes it wont, but you wont know until you try. Quite often with this type of image you will need to have your aperture wide open (big) as this will lead to a narrow depth of field and so to a small part of your image being in focus with a large part being out of focus. This produces the dreamy, ethereal effect many people like.
The image shown above of a white tulip was just one out of many shot on that day. Most of the images taken were of several tulips together but on reviewing the pictures they seemed somewhat ordinary. It wasn't until near the end of the shoot when I was just trying to think of a few more ways to capture these beautiful flowers that I did a few close up images. This one shown turned out to me one of my favourites - it is simple, soft and gentle and I think it reflects the nature of the tulips very well.
