How to Make an iPhone Screenshot

Want to take a screenshot of something on your iPhone or iPod touch? Press the Home button and Power button briefly at the same time, and an image of your screen will be saved to the Photos app (and will sync with iPhoto when you next connect). Don't hold the buttons too long or your device will either power down or reboot.

Asiva Plug-In Demos Now Available

Send Article to a Friend

In my last TidBITS article I wrote that the main reason I use Photoshop is to run Asiva's plug-ins, especially Shift+Gain. Last year Asiva shut up shop, leaving these products unavailable, but they have been purchased by their original developer, who is marketing them again. He is also now, at long last, providing demo versions, making it possible for people to try the products before committing any money. In addition, he has cut their prices and renamed three of the plug-ins to clarify their functions. Here is the line-up. The set of four costs $99.

Current Name      Former Name      Price
Correct Color     Shift+Gain       $39
Replace or Apply  Correct+Apply    $39
Sharpen or Blur   Sharpen+Soften   $39
Selection         Selection        $29

These plug-ins allow you to select tones and manipulate them based on their hue, saturation and intensity. Hue, saturation and intensity approximate the perceptual dimensions that the brain works with, so manipulating tones with Asiva's plug-ins is more straightforward than manipulating tones in conventional ways that are analogues of film or are based on the computer's channels of red, green and blue. Asiva's plug-ins enable direct, vector adjustments that would normally require handwork and/or complex masking. Asiva's approach is patented, so these are the only products of their kind.

I use Correct Color for almost every photo, in lieu of all of Photoshop's colour-correcting tools (for details, see "Editing Photographs for the Perfectionist," 2004-09-27, and "Reality and Digital Pictures," 2005-12-12). Replace or Apply is the simplest way I know of to change the colour of a sky or of a discordant piece of clothing or background. Selection lets me select skies and other smooth tones so that I can remove noise only from those areas and retain detail elsewhere. Sharpen or Blur I use occasionally for softening bright elements in portraits.

These plug-ins are available for any version of Photoshop back to 5.5, for any kind of Macintosh or for Windows. The Macintosh demos are universal binaries that will work on an Intel- or PowerPC-based Mac, but they require Adobe Creative Suite 3 and Mac OS X 10.4.8 or later.
