Human Hair

Two intertwined human hair under the microscope. The original image. The field iris diaphragm is still visible at the corners.

The power of image clean-up: dust and dirt removed.

The pictures on the right show you the original, unprocessed image at the top, and a second cleaned-up image with a nice background on the bottom. The top image shows darkened corers from the field diaphragm (from Köhler illumination). I closed the diaphragm quite a bit in order to increase image contrast (I intended to crop the image anyway). Then I did some processing in PhotoShop (or was it GIMP?). I selected the hair to remove dust and dirt and placed it on a nice blue gradient background. The most difficult part of the project was the making the hair knot and finding of an appropriate focus of the relatively thick sample. I did not do any image stacking (combining several images into one to get one final image which is sharp throughout).
