Fellow bloggers Steve and Steve often include beautiful close-up photos of leaves in their posts. They inspired me to try imaging leaves in a different way. I decided to use a flatbed scanner. During a recent walk, I picked up three examples that were colorful and still in good shape. I got a pin oak, maple, and ornamental pear and headed home.
First up on the scanner was the oak leaf. I placed it face down on the glass and set the resolution to a high value of 800 dpi. I wanted to get lots of detail in the scanned image.
That turned out pretty nice showing the leaf vein structure and cells. Next up was the maple.
Each image above was made by reflecting light off of the surface of the leaf. My scanner can also image 35 mm slides. That process requires the use of a light source in the lid of the scanner so it can project through the color transparency film of a slide. The maple and the pear leaves were thin enough to allow a large amount of light to pass through them much like a 35 mm slide. I figured it was worth trying to scan them using the slide setting. First, I did the maple leaf on the 800 dpi transmission setting.
That turned out better than I expected. There was more detail revealed than the reflection setting. The image above is a 1 inch square area. I tried higher resolutions of 1200 and 2400 dpi of the same part of the leaf? The next images are of areas 2/3 and 1/3 inches square.
Not much detail was gained by the 2400 dpi setting. It did render a much larger and slower scan. I had one more leaf to try, the pear. Both images below used the slide transmission setting. The leaf detail is quite different from the oak and the maple.
That was fun to view the autumn leaves in a different way. I’m beginning to think of other transparent objects or things in nature that might be interesting to view this way. Do you have some ideas to share?
