JASC Paint Shop Pro 9

Paint Shop Pro (PSP) may have begun life as a simple shareware bitmap editor, but it's managed to transform itself into a professional photo editor that gives even Photoshop a run for its money.

This latest release adds a number of features aimed at the high-end digital camera user. To begin with, PSP's image browser window now offers an Info palette to show the EXIF data, such as aperture and exposure, that modern cameras automatically store with their images. PSP 9 also now supports the unprocessed RAW sensor data captured by professional cameras and lets you set customised white balance, exposure and sharpening settings for import.

Once you've opened your photos, the latest PSP also offers a number of new enhancement filters: Digital Camera Noise Removal intelligently removes image noise introduced at the sensor; Chromatic Aberration Removal eliminates the occasional undesirable coloured glow around objects that digital cameras can introduce; Fill Flash corrects underexposed shadows; and Backlighting corrects overexposed highlights. Two new special-effect filters have also been added in the form of Displacement Map for creating 2D and 3D surface distortions based on an underlying image, and Radial Blur for creating spin, twist and zoom blur effects. And when it comes to outputting your photos with PSP's excellent Print Layout dialog, you can now add freeform text captions to your print-outs.

Handling and enhancing existing photos is certainly PSP's most common role, but the program is also capable of originating images from scratch. And it isn't limited to bitmaps either - PSP pioneered the use of vector layers to provide integrated drawing capabilities. With version 9 these are enhanced with new Rectangle and Oval tools (previously these were available as presets), and simpler handling for the Pen tool. Completely new are the Symmetric Shape tool, designed for adding customisable polygon and star shapes, and new Text tool options for producing vertical text and improving the rendering of smaller font sizes.

Alongside its surprisingly impressive drawing capabilities, PSP 9 adds completely new art-based painting features clearly inspired by the market leader, Corel Painter. This comes in the form of new Art Media layers on which you can paint with a range of new natural media tools - Oil, Chalk, Palette Knife, Pastel, Crayon, Colored Pencil, and Marker - each designed to closely mimic its real-world counterpart. Using the Oil Brush tool, for example, the multibristled brush lays down multiple pigments that interact with both the underlying paint and canvas texture until the brush stroke realistically runs out of paint.

The aim is to make working with the Art Media tools feel like working with traditional artist's tools, an idea reinforced by PSP 9's new traditional-style Mixer. Like a real artist's palette, this new dockable palette provides an off-canvas area in which you can add, mix and then sample your paint ready to apply. Alternatively, you can set the colour that your Art Media tool applies to Trace, which means that the underlying colour is automatically sampled when you first begin painting - ideal for producing an artistic version of an existing photograph.

The results can be impressive, but there's a major downside as the amount of processing involved leads to serious time lag as your strokes are laid down. Because of this, painting in PSP lacks the spontaneity of working with traditional art media, although you've all the advantages that working in a computer environment offers, such as the ability to immediately undo any stroke that you regret. And the latest PSP drives home this advantage with its new History palette. This lists all commands as they're applied to an image, and you can simply choose an earlier stage in your work and undo all changes since then. Even better, you can also undo individual steps without affecting subsequent actions, such as deleting a single earlier brush stroke. You can also select multiple steps and then save these as a script that can then be applied to any other image.
