Leonardo Capradossi | Knotted Blonde Hair
Name: Leonardo Capradossi
Picture title: Knotted Blonde Hair
Occupation: Biotechnology student
‘The human hair in this image is enlarged about 200x, making the keratin scales on the outer surface clearly visible. To fill the frame and to create an original picture, I decided to knot the hair in the shape of a pretzel.
I didn’t use microscope slides for this image, but because the hair is so thin and susceptible to the smallest vibrations I had to make a special fixing support. I used an optical microscope to capture the picture with an external flash and a specialised, 3D printed diffuser. Focus stacking was crucial to the picture, and 85 shots were needed to get the whole subject in focus.’
Olympus LMPlanFl 20x 0.40 bd
Technique: Darkfield, reflected light and focus stacking (85 shots).
Magnification: 200x magnification (RR 20:1).
Accessories: Episcopic microscope and a diffused flash (Nikon sb700) for the reflected light.
Post processing: Adobe Lightroom for the basic adjustments and Zerene stacker for the stacking process.
