Calibrating Monitor with DisplayCAL for Mac

Here is an easy walkthrough using the DisplayCAL software. DisplayCAL is an Open Source Display Calibration software. More info can be found at there website DisplayCAL. The software requires that you use a calibration instrument listed here.

There are a few steps to go through before you start the calibration process.

  1. Set your monitor to 6500K and ruffly adjust your brightness and contrast levels before you do the calibration with DisplayCAL.

  2. Set the whitepoint to 6500K. 6500 Kelvin (a.k.a.D65) is commonly used as a standard illuminant / white point for photography

  3. White Level. Set the target brightness of white in cd/m2. You will have to try out what works best for you, but a good starting point is 80-100cd/m2.

  4. The target response curve is normally set to 2.2.

  5. Calibration speed determines how much time and effort to go to in calibrating the display.

Freedom for all

Everyone deserves freedom. Nowadays we humans take freedom for granted, but what about animals? It breaks my heart when I see captive animals. Especially animals that are abused to entertain us human’s amusement. There are so many sad stories in the world. What happened? When did we humans get so foolish? I can’t stop wonder, have we always so been so cruel throughout time towards animals, or is this something that has happened in recent century?

I am driven by empathy and consider myself as a conservation photographer. All my life I’ve been drawn to nature and what it can offer. Seeing, experiencing nature and wildlife as it should be, is truly a unique experience. There are so few untouched places left in the world that we all should do what we can to maintain these places and the animals that live in them.

So, what can we do? Here are a few examples what you can do.

  • Be an ethical tourist and never take your picture with a captive animal

  • Do not keep a wild animal as pet unless you have a written permit from the government

  • Recycle and buy sustainable products

  • Do not buy plastic products

  • Educate friends and family

  • Donate and support wildlife organizations

  • Research before buying stuff. Ask these questions before making a purchase:

  • What is this product made of?

  • Where did this product come from?

  • Does the country I’m visiting allow the sale and export of this product?

  • Do I need permits or other documents from this country or the United 
    Is it allowed to bring this item home?

According to the latest report from WWF

We stayed at the Mara Eden Safari Camp. A simple but nice camp with great staff. The camp is situated perfectly. Just at the Mara River, which makes travel time very short where the action is.
