In-Depth Information
Plug-ins are basically applications within an application: they can range from
the simplest of i le readers (which, i rst and foremost ACR is) to the full-
featured adjustment tools (which, as it happens ACR also is) and i lters.
Plug-ins constitute many of Photoshop's abilities to read, write and i lter
images and are developed by Adobe as well as a dizzying network of
hundreds of third-party developers.

Version 5.0, Adobe Camera Raw of ers even more control!
Photoshop CS4 ships with version 5.0 of ACR; this revolutionary release
maintains feature parity with Lightroom 2.0, and that means selective edits in

powerful paint and selection engine, but rather a high-volume solution for
common, minor edits. Of course, by integrating with Lightroom, that which
you see in Bridge and ACR looks and works the same as it did in Lightroom
(and vice versa).
More specii cally, ACR now has two incredibly powerful new tools (neither is
available in Photoshop):
Graduated Filter (G)
Beyond just neutral density (exposure and brightness), we can now have
multiple graduated controls of things like color, saturation, clarity, sharpness
and tone! Of course, like everything in Camera Raw, these are live and
re-editable and they can be shared and synched amongst other i les or saved
as presets.
Adjustment Brush (K)
All of the controls of the Graduated i lter wired to a brush! This is metadata-
based editing taken to a whole new, selective, paint-driven level. As with
