Figure 2 - Improving an image by redesigning.

a, Patterned hydrophobic lines, 3–4 mm long, on a self-assembled monolayer (SAM) stop water from further wetting the surface. This image was made by the researchers for their notebook and used in the published article. (Image reprinted with permission from ref. 6. Copyright (1992) AAAS). b, At my suggestion, the sample was redesigned to further communicate the significance of the lines. In addition, by colouring the water before dropping it on the SAM, the purpose of the investigation is reinforced — that the lines are preventing the water from blending together. Note, as well, the not-so-trivial issue, that the image in b is in focus while the other is not. Image b was used on the cover of the journal. (Image by F. Frankel.)
