Photographing flowers and surely a lot of other things need at least a good preparation.
Choosing the right lens, may be having a tripod and prepared everything beforehand to take the image, facilitates a lot. Before pressing the shutter you should ask yourself some questions :
Shall I crop it – getting close or stay on the wide side?
What is for me the point of interest?
Do I have the right angle, the best perspective?
Shall I go crystal clear with a lot of depth of field or wide open ?
Are there distractions in the background and/or foreground?
In my opinion the last question is one of the most important!
Taking flower photographs you will find yourself in a lot of situations with potential distractions. There might be fences, other flowers, cloth lines, tools and many more. You have to decide whether you want to include these elements or remove them. Depending in which way you think it will enhance your shot. There are different options to remove distractive elements like:
Move – the distraction or yourself, get another angle with less distracting background, crop the image tighter
Use your aperture to narrow depth of field. As you do this you make elements in the foreground and background more and more out of focus.
As a general rule in photography you need to think about where you want your viewers eye to be drawn to. Using the rule of thirds is one way – but even better if you can find something in the frame that will grab the eye of the potential viewer. If there is something alike try to position it accordingly.
Don’t look only on the wonderful and beautiful flowers. Look as well for the ‘ugly duckling’ beside it. Sometimes the flowers which are going dry, loosing petals etc. are more interesting than the others.
Sometimes going abstract is a wonderful decision. Showing only a part of the flower can create an interesting and unusual image. Look as well out for contrasts in colour, pattern and/or texture.
One thing that will make your image or destroy it is sharp focus. In my opinion this is very important especially in flower Macro photography. Even a tiny adjustment will have implications for your photo. The depth of field is so small, sometimes a matter of millimetres. Getting this detail in focussing is something you never should neglect.
I try to make my point of interest to be in focus and as sharp as possible. Sometimes this is a real challenge, especially outdoors if you think on windy days. There is a great possibility that you’ll end up taking a lot of photos and have to rely on luck to get your sharp one! Improving this situation is only possible in a controlled environment (studio shots, shielding from wind or waiting for a still day).
As light is the main factor in taking photos not only consider the golden hours but try to enhance your situation with flashes, reflectors, filters and so on. Just experiment.
Have fun and go shooting!
