A couple of years ago I bought a secondhand macro lens (Nikon 105mm Micro) and did some focus stacking with withered roses to get a sharp image all the way down into the roses. Now, during the corona crisis, that I am confined to my house and garden, I start to value the little things in life, like a budding flower, or a bumblebee. So now, I am using my macrolens continuously to capture all these beauties. I never thought I would be taking pictures of flowers and insects. Honestly, it is much harder than I expected. Almost always I am facing challenges, and I love it.
To share the love for these beauties of nature I hunt everyday in my garden to find new buds, flowers, or insects. I know my garden now much better than before. The pictures I like, I share them on Instagram (have a look at the right column of this blog). The pictures that are of the highest quality are submitted to Dreamstime. Currently the review process takes less than one hour.
In the ideal world a flower (or a detail) should be the main subject of the picture, well-lit, tack sharp, with a non-disturbing blurry background. And, of course, no noise in the picture. The combination turns out to be a challenge.
As you probably know, shutter speed, aperture, and ISO depend on each other. Changing one has an effect on the others. This is called the Photographic Triangle.
For example, the depth-of-field at 30cm from the flower for a 105mm lens at f/11 is only 0.4cm. Can you imagine! If you move just a little bit the flower is out of focus. Increasing the depth-of-field to 0.7cm by going to f/22 means either a slower shutter speed or an increase of ISO (introducing some noise in the picture).
A consequence of an increase of ISO means that objects in the background become more visible, distracting attention from the flower. A slower shutter speed, on the other hand, seems fine if we use a tripod; however, if it is too windy or if the insect is moving, it is not going to work. All in all, it is not as easy as I thought.
In the upcoming posts I will have a closer look at some of these challenges.
