Tutorial—Mac OSX Password Reset

OS X: Password Reset Using Recovery System

Recovery System

Instead of a set of utilities and recovery CDs, OS X Lion or OS X Mountain Lion stores these applications on a disk partition. To access this recovery system, restart your Mac, after hearing the Apple startup gong, hold the Command and R keys (Command-R) until the Apple icon appears. After the Recovery System is finished starting up, you should see a desktop with the OS X Menu bar and a “Mac OS X Utilities” application window.



Launch the Terminal Utility by selecting Terminal from the Utility menu.


Enter the following command in the Terminal Utility window command line:

In the Reset Password window, select the disk volume containing the user account requiring the password reset. Select the user account from the pull down menu. Enter the new password in the appropriate text boxes. You can optionally provide a password hint. Click Save.


Select Restart from the Apple Menu.

Note: When logging into the user account for the first time there will be a warning indicating that the system was not able to unlock the account’s login keychain. Since that requires the old password, select “Create New Keychain.”

Tutorial—Quick Selective Adjustments in Snapseed

Import image from Camera Roll or take photo from within Snapseed. Select from the bottom menu: Selective Adjustment. Select Adjustment offers control over select areas in saturation,contrast, and brightness. Assess your image and decide what portion of the image needs adjustment. This could be a brighter or darker area such as a sky, shadows, color element, Tap the +sign to add a Control Point to the image. For the purpose of this mini tutorial, I will add a control point to a sky image.

The control point will change to the default of B for brightness change. By placing two fingers on the screen and swiping outward to zoom, a red mask will appear on image and this will be the area that will be adjusted. By pinching to decrease the mask or zooming out to increase the area of the mask, you can be specific about the image adjustment.

To adjust the brightness, slide your finger from left to right to increase the effect and right to left to decrease. The blue button will have a green ring around it to show the increase and a red ring for the decrease. The bottom of the screen has a measurement dial so you can be numerically precise if needed.

To change to brightness button to contrast and saturation, tap the screen and slide our finger up and down. A small tab menu slide will appear and then you can select the adjustment you want.

You can also slide your finger over the image to pick up the color you want adjusted. For example, if I had an image that had two boats with red smokestacks and I wanted to only pop out the red, I would slide my finger over the smokestack until I saw red in the little circle crosshair icon, zoom out to create the mask over the elements of that color in the image, then slide from left to right to increase the saturation. Be sure you have changed the icon button to the effect you want.

You can add several adjustment points to your image for greater control of your final photograph. Adding adjustment points for brightness in one area, and contrast in another area, offers a robust photo-editing experience on an iDevice. Snapseed gives the user tools to make local and global adjustments to a image it saves in high resolution. You can also use the two finger zoom method to create a mask that encompasses the entire image, to increase or decrease an effect over the entire image.

To compare the adjusted image to the original image, press the compare button located bottom left of the screen.

Snapseed Image Tutorial

Screen shot 2013-01-28 at 8.18.15 AM

Tap on + sign, then tap on image to create an adjustment point. B=brightness, C= contrast, S=saturation. To select these tap and hold anywhere on screen and slide finger up and down to open tab menu. I wanted to pop out the red in this flower, so I selected S to increase the saturation.

Notice the green ring around the S, if I had decreased the effect, the ring would be red. The dial at the bottom center shows the increase and decrease on a scale.

You can create several different adjustment points within an image. When using the two finger zoom out gesture, this action creates a mask for the adjustment area and appears red. Slide your finger left to right to increase the adjustment or right to left to decrease it.
