From: Reduction of Salmonella contamination on the surface of chicken skin using bacteriophage
Time-lapse negative images of Salmonella growth on chicken skin following treatment with buffer (C) and phage (P) after 2 min, 3 h and 6 h, incubated at room temperature (~ 20 °C). A negative image of the logarithmic colour palette used by the Photek IFS32 software is presented on the right of the figure. Each colour represents the log10 number of photons collected at a given time point (1 min). The numbers on the right represent powers of ten (e.g. 2 = 102 photons). All images were processed identically using Adobe® Photoshop 7.0 (Adobe Systems Inc., San Jose, USA) on a Viglen Genie XL280 PC running Microsoft Windows XP
