Hi All, (full text and images at https://docs.google.com/open?id=0B6J5ZA1hu93bYm9IWXdlVHM1N1U )
Recently landuse=farmland (or simply landuse=farm) has been added to fields near me. This has led to a discussion about how the rendering 'looks' with some arguing that it doesn't look that good. I believe that this may be due to the shade of colour used – specifically the farmland 'brown' is not as luminous as the default 'grey' (actually I think it 'lightness' rather than 'luminosity' that matters to the human eye but I got very confused when searching the two). Consider the image below, showing current rendering: https://docs.google.com/open?id=0B6J5ZA1hu93bZDBTN2dZZkpDenc On the left we have farmland tagged. The 'brown' has a Lightness value of 83 percent (luminance of 85%). Compare this to the default canvas 'grey', which has 93 percent Lightness (and 93 percent luminance). Now consider the following (and please check your screen calibration at http://www.photofriday.com/calibrate.php ). I have taken the farmland 'brown' and raised it's Lightness to the same 93 percent as the default 'grey' (that is, I have left the Hue and Saturation the same): https://docs.google.com/open?id=0B6J5ZA1hu93bSzk5NDZVMm5GZkE In this final image, I have adjusted the Hue and Saturation to provide more of a 'green': https://docs.google.com/open?id=0B6J5ZA1hu93bZXhzdVJMVU44X2M What are your thoughts? Which do you prefer? Have I gone too 'light' with the change and should some value in-between be used instead? Am I barking up the wrong tree? Regards, Rob Note: To focus discussion I want to avoid the argument that some people see farmland as the default and therefore it does not need to be tagged – it is a legitimate land-use tag and if people want to tag it then let them.
