CALIBRATION + About + Links


I use this target to calibrate my display: If you want to see the pictures in this blog same as I see them when prepare for publishing, use this target. Left vertical double-bar has to have visually equal densities on the left and on the right halfs. Middle triple bar has to look all monochrome. This is achieved by changing the monitor gamma. Your video driver must have it under advanced settings, color tab. After you are done with gamma, fix the black point (brightness on the monitor) so that on the right-bottom bar you do not see stripes, and on the top-right bar you see them. Voilas! I choose gamma = 1.8 by three reasons. The smaller gamma - the less gamma error. When processing 8 bit images it might get critical in dark details when you visually compare image correctly displayed at g=1.8 versus one corrected for g=2.5 My printer (Epson 785 EPX, Rest In Peace) prints monochrome in g=1.8 and g=2.2. The 8-bit driver is producing noticeably more tone separations in the darks at g=1.8 than g=2.2 so I process all images at g=1.8 to match the prints. The standard gamma for PC is 2.5, not 2.2. Thus if I prepare images in 2.2 everyone with standard gamma will see them just dark and criticize me for that because the difference is small. With gamma = 1.8 the images ar very-very dark and it's an indicator that something is really wrong with the monitor. Once monitor is adjusted, everything becomes fine. The fourth reason is not specific: all MACs have gamma 1.8 (1.72 to be true) and most of the modern PC monitors are getting there too. Later I might change to 2.2 or 2.5 if I feel right about it.
