John Gruber mentioned in a recent post about Apple's Snow Leopard list of Enhancements and Refinements that one of the small adjustments to Snow Leopard will be that the default gamma on displays will switch from the typical 1.8 value to 2.2, which is what is used on TVs as well as being the long-standing default gamma value in Windows.

Gamma affects the visual contrast you see on your screen, and a higher value indicates a higher level of contrast. The cost of this higher contrast is that you lose some detail on the less luminous parts of your screen.

If you're interested in seeing what this is going to look like in Snow Leopard, or switching your gamma setting now so that you're used to it ahead of time, here are the steps to do it using the Display Calibrator Assistant:

1. Head into System Preferences, and click on the Displays icon.
2. Click on the Color tab, and press the Calibrate... button.
3. On the Introduction window that opens, click Continue
4. On the next screen, "Select a target gamma", choose "2.2 Television Gamma"
5. Click Continue leaving your Target White Point set to Native (or whatever yours is set to)
6. Now name the new profile you've created, click Continue and then Done.
7. Lastly, you can now choose to switch between your default color profile, and your newly created profile with the gamma set to 2.2.

I realize this might seem terribly obvious to some users, but for others playing with color profiles is not ground they've previously covered. If you're one of those people, this tip is for you.

With the introduction of EPEAT Gold rated MacBooks and MacBook Pros last week, Apple has definitely been warming up to the environmental movement lately. So, it was only fitting that they would change a small part of System Preferences to reflect the EPEAT rating.

That's right, the Energy Saver icon has changed from an old incandescent bulb to a newer, more energy-efficient fluorescent bulb. Now you will only have to change the energy saver icon every 7 years, but be careful when you dispose of the old icons because they contain mercury (just kidding).

This change has only shown up on the new MacBooks and MacBook Pros. Do you think Apple will eventually update their entire line to have this new icon (and, of course, be EPEAT Gold rated)? We definitely hope so!

A German site, Apfeltalk.de has posted screenshots of the forthcoming version of Mac OS X, 10.6 (a.k.a "Snow Leopard"). Most of the screenshots show off the Safari 4 developer preview that will include the "Save as Web Application" option in the File menu.

The website also shows off the next version of Address Book.app that will bring Microsoft Exchange support to the Mac platform. We do however have to speculate about the System Preferences.app screenshot that shows two Time Machine icons with one labled "Dock" and another labeled "Time Machine" -- this seems out of place and unlike Apple.

You can see all of the screenshots (before Apple's legal team gets a hold of them) on the Apfeltalk.de site.
