Three Must-Have Photoshop Plug-ins :
1)Noise Ninja is one of the newer kids on the block, but in the couple of years that it's been available it has gone through constant upgrades. A new plug-in version has been in public beta for some months during late 2004, and in Feb 2005 has started shipping. As good as Noise Ninja was, I am always frustrated by image processing utilities that are stand alone programs. Having to switch back and forth between programs, loading and unloading files, can slow one down. Plug-ins simply make the workflow that much more straightforward.
2)Convert to B&W Pro (CTBWP from now on) is a Photoshop plug-in that actually makes the conversion process a joy. You are provided with a variable size preview window, (only on the new Mac version, regrettably), and a full set of tools for adjusting the image to just the way you want it to appear. And for those photographers coming from a background in black and white film processing and printing, the controls are even labeled with their analogue equivalents, right down to being able to choose multi-grade contrast.
3)Photokit Sharpener. Designed and written by six of the world's leading Photoshop educators, Photokit Sharpener is a powerful set of image sharpening tools designed to approach the task appropriately from both a workflow and an image quality perspective.
