Software Notes
Some people claim that images displayed on a Safari browser look better than that on Firefox. This turned out to be caused by inability of older Firefox to adapt system's color management conventions. Thus, if you calibrate your system using Spyder, or Colo Munki, or Pantone Huey, your images will look calibrated using 'preview' but will look slightly off color on Firefox.
You might have read all the fancy publications on how to convert your photo from colour into BW (btw, the title is not making BW photo because we don't use BW films anymore with all the different coloured filters attached).
