The above macro image shows a hover-fly on an Echinacea blossom. It’s taken by using a 105mm macro lens attached to a camera with an APS-C sized sensor in the early evening hours. Afterwards it’s developed from raw by using Luminar 2018.
Insects are very quickly moving animals. Additionally, their movements are nearly unpredictable. Even when sitting on blossoms for having a meal, they are constantly moving around. So, you have to use very short shutter-speeds when taking photographs beside a quick auto-focus. When using a macro lens for taking photos from small or tiny things like insects, you have to use a small aperture (= high number) to get images that are sharp for more than a tiny area. You know, the size of the field of depth depends on the focal length and the f-stop as well as the distance between your lens and the subject: the smaller the aperture, the bigger the field of depth and the longer the focal length the smaller the field of depth.
Both of these have an impact on the resulting image: a short shutter-speed only lets the light reach the sensor for a very short moment, while the small aperture limits the amount of light. So, what can we do to get properly exposed images? Right, we must increase the ISO, the sensitivity of the sensor. But, increasing the sensitivity also has a con: the digital noise in the image also increases and the fine structures might vanish. You might ask, why do I tell you all this technical stuff.
The reason is, nobody wants to look at noisy images with no structures. So, you have to use a software for developing your images, which is capable of eliminating the noise but preserves the structures.
In this image I still have all the structures: the fine hairs, the structures of the facet-eyes and the pollens. I also got rid of the noise from the background. So, Luminar did a great job again.
