By darkening the photo or even turning down the brightness on your monitor, what you now have created is uneasiness, apprehension, a thickening tension about what is about to come out of that dark center spot. If you lighten up on the photo, the branches of the tree in the center become more defined and you create a softer feeling that Mark describes.
JohnL brings up a good point. I suspect that very few of us have calibrated our monitors and the color temps (should be ~6500K), gammas (net gamma should be 2.2), brightness, and contrast vary considerably. Thus we are likely viewing different images.
One can get formal calibration gear which uses a small camera-like device to measure the output of your screen and calibrate it (ICC profiles and all that stuff). One can also use some network facilities do a cheap and easy approximate calibration.
One simple procedure:
1. If your monitor has the appropriate adjustments, set the color temp to 6500K.
2. For the rest of the procedure, the room should be dark enough to prevent reflected light from altering the images. The monitor should be on for at least 15 min to stabilize.
3. Go to
http://www.normankoren.com/makingfineprints1A.html#gammachart. This chart will enable you to check the gamma of your system (graphics software, graphics card, and monitor combined). If you have some method of adjusting the gamma, adjust it until the gamma reads out at 2.2. (You might also want to read this page--there is lots of good info on the issue.)
4. Go to
http://www.pcbypaul.com/software/monica.html and look at the grey scale just above the colored squares on the screenshot. Adjust your monitor contrast (which actually adjusts the black level) so that you can see the entire greyscale with the black block truly black. Adjust the monitor brightness (which actually adjusts the max intensity) to your preference.
5. Repeat 3 and 4 several times as they may interact.
Notes:
* I use Linux so I can't tell you how to adjust the gamma on MS OSes or Macs. ("Xgamma" will do it under X-windows in Linux/Unix.)
* For casual viewing with too much room light, I temporarily increase the gamma and wait until the room can be darkened for critical viewing.
Happy screwing up your monitors...
