Thistle (Carduoidea) -  Pappus

The photo is taken with our LM macroscope and a full-frame camera. We used the focus stacking technique to obtain the ideal depth of field. Focus stacking is an image processing technique that combines multiple images (up to 100 individual frames) into a “stack” of images. Focus stacks can be created by turning the micrometer screw and repeatedly triggering the shutter, but a much more elegant and less complicated solution is to use a motorised focusing rail. The LM macroscope is factory-ready for installation of a motorised focusing rail. Once the stack is completed, it is processed with a special software tool. The result is one composite image that is sharply focused from front to back.
