Sexual Skin Color Contains Information About the Timing of the Fertile Phase in Free-ranging Macaca mulatta (2009, methodology): “148 149 To verify whether our method measures color accurately, we tested our outputs for a linear 150 relationship to light intensity and determined whether the reflectance values of the 3 color 151 channels were equal (Stevens et al. 2007; Stevens et al. this issue).”
The evolution and function of pattern diversity in snakes (2013, methodology): “…images taken in uncontrolled conditions, either objectively using spectral measurements (Endler 1990) or transformed camera pixel values (Stevens et al. 2007), or subjectively using, for example, color chips, this approach offers a way of capturing the rough properties of a snake’s…”
Camouflage through behavior in moths: the role of background matching and disruptive coloration (2015, methodology): “When photographing, we positioned the camera lens at the same height as moths and used slightly under-exposure setting to avoid saturation (Stevens et al. 2007).”
Using digital cameras to investigate animal colouration: estimating sensor sensitivity functions (2011, methodology): “This demonstrates that, despite these slight inconsistencies, the estimated sensor sensitivities allow sufficiently accurate mapping functions to be derived to map between device and animal colour spaces with a high degree of precision (with the only caveat being that the number of cones must be les”
A framework for analysing colour pattern geometry: adjacent colours (2012, methodology): “For example, calibrated RGB images can work for bird coloration if UV patches are absent (Stevens et al., 2007).”
Color change and camouflage in juvenile shore crabs Carcinus maenas (2014, methodology): “…(SWS), violet-sensitive (VS), and double cone (D) types by using a polynomial mapping technique to convert from camera to bird color space (see Westland and Ripamonti, 2004; Stevens et al., 2007a; Pike, 2011) using a custom written program in Image J, using a D65 standard irradiance spectrum.”
Image calibration and analysis toolbox – a free software suite for objectively measuring reflectance, colour and pattern (2015, methodology): “To date, the linearisation process has generally required expensive, specialist equipment and coding skills (Barnard & Funt 2002; Stevens et al. 2007; Garcia et al. 2013).”
A simple method for measuring colour in wild animals: Validation and use on chest patch colour in geladas (Theropithecus gelada) (2008, methodology): “However, in cases where smaller, more detailed comparisons are necessary (e.g. patterns on the wing of a moth), it is preferable to use uncompressed images (TIFF or RAW) as recommended by Stevens et al. (2007).”
