Alien Skin Snap Art - A Photoshop Plugin For Instant Artistic Effects

Alien Skin's new Photoshop plugin Snap Art creates beautiful, natural media artwork in a single step. This ten filter plug-in set includes effects for oil paint, pencil sketch, pen & ink, comics, color pencil, and more, and is capable of creating an unlimited variety of real-world art styles. For the advanced user there are detailed controls available to fine tune a composition.

Artists often use an underdrawing to outline key objects within a composition. This lightly drawn sketch serves as a guide, and it is usually painted or drawn over in the final composition.

Snap Art's advanced edge detection accomplishes the same goal, intelligently determining the shapes of the objects in the original image. Using this outline, Snap Art’s advanced paint engine strokes and fills the image with brushes and colors specified by the interface controls. This enables realistic reproduction of detail, but balances realism with convincing artistry.

Like other Alien Skin plug-ins, Snap Art includes many helpful usability features. First, there are keyboard shortcuts similar to those found in Photoshop. The online help and the Quick Start Guide include a complete list. Next, Snap Art includes filter-specific help. The F1 or Help key launches the online manual.

Snap Art is also scriptable with Photoshop Actions. Applying a setting to a folder of images as part of a batch process will quickly give them all a hand-crafted look. For photographers importing RAW files, Snap Art supports 16-bit images.

Review Of Snap Art By Jennifer Apple

As Alien Skin states, Snap Art features a variety of brushes, pencils, pastels, and pens, as well as an assortment of canvas and paper types, and includes hundreds of presets that can generate artwork with a single click. So after a few minutes in a hassle-free installation, I was ready to go.

For the purposes of this review I decided to use the same image for the various effects I would try. I took my favorite holiday image (Peter Bower's snow and trees shot, which is the image on the right) and I zapped it in Snap Art.
The first sample image you see below was created from the Pencil Sketch Effect set.

Once inside the control panel for Snap Art's pencil sketch effect, I tried a variety of defaults and finally settled on "assorted - dense hard pencil." A few seconds later I had my newly drawn artwork in front of me and I was totally impressed. The fine detail and the balance of light and shadow were superb. I was also very happy with the "vibe" of the piece. It had a truly natural feeling that's hard to achieve with some of the other art effect plugins that are on the market.

Next I went for a filter called Impasto, an oil painting style that features a thick, textured application of paint that actually highlights the marks made by the painting brush or knife. I clicked on the default set listed as "assorted - more detail" and again, I was completely impressed with the results.

I found the effect subtle, not at all overdone, but the best part for me was that I could actually make out the original source file, which is the real challenge and what makes or breaks these type of effect filters. I want to maintain the original look as much as possible, and layer the effect over it, instead of having the piece transformed beyond recognition.
Of course many of the effects offered in Snap Art can be achieved through a series of manual steps in Photoshop, but they need to be followed exactly, and they often take quite a bit of time. Also, doing it step by step leaves you retracing your steps when you're not quite satisfied with your results, whereas with this plugin and the incredible variety of options, you can really go wild trying literally thousands of variations. That's the beauty of well-programmed, well thought-out plugins, and Snap Art definitely falls into that category.
The rendering time in the preview pane was not as fast as I would have liked, but of course as you become more familiar with the plugin, you'll find getting the look you're after will become much more intuitive — with much less time spent twiddling with the slider settings.

Again, the beauty of this plugin is in the quality output, the simple interface, and the whole concept of a "one-step" push button solution, which makes a designer's life a real pleasure. Of course part of that pleasure might be in keeping the plugin a secret. Need to mimic a Van Gogh painting, you say? What was that - by this afternoon? That's not going to be a problem with this plugin set.

The only thing missing is a mouse pad shaped like a palette and a beret — to celebrate my newly acquired artistic skills that this plugin delivers.

Snap Art Filters, User Interface & System Requirements
  1. Pastel Effect
    The Pastel filter simulates pastel painting with regions of soft tone and color. Pastel includes options for soft, hard, and oil pastels, as well as controls for paper type and lighting.
  2. Impasto Effect
    Impasto is an oil painting style that employs a thick, textured application of paint where the marks made by the brush or painting knife remain visible. The Impasto filter emulates this technique with a variety of brushes, strokes and canvas types.
  3. Oil Paint Effect
    The Oil Paint filter models the thickness of stiff oils or the lightness of lean (thinned) paint. With controls for brush size, paint thickness, and stroke length, this filter captures the richness of painting with oils. In addition to brushes, users have control over canvas and lighting to portray unparalleled realism.
  4. Color Pencil Effect
    Color Pencil uses hatching and shading techniques, as well as control over pencil width, pressure, and color to recreate an image as a sketch artist would. Additional options include a variety of paper stocks and lighting controls.
  5. Comics Effect
    The Comics filter gives a photo the look of a comic strip with posterized colors, shading, and halftoning. Control over the number of colors and halftone size can create a unique look or mimic Roy Lichtenstein Pop Art.
  6. Pencil Sketch Effect
    Pencil Sketch creates detailed sketches that emulate either graphite pencil or charcoal. This filter makes extensive use of hatching, cross hatching, and shading.
  7. Pointillism Effect
    Created by the French Neo-Impressionist painter George Seurat, pointillism is a distinctive painting technique that uses dots of solid color that blend together when viewed from a distance. Snap Art’s Pointillism filter does exactly that, offering control over dot size and color palette.
  8. Stylize Effect
    Stylize converts images into smooth regions of color. This filter can create a posterized Pop Art look or flowing line art and logos. Additional controls are available to add texture and determine the direction and intensity of the lighting.
  9. Watercolor Effect
  10. Watercolor simulates the soft color washes created by watercolor paint and paper. Controls for brush size and style – including wet and dry brush – provide control to preserve the fidelity of the original image. Paper choices include various textures for Hot press, Cold press, and Rough paper types.
  11. Pen and Ink Effect
  12. Pen and Ink represents an image as monochrome dots, lines, and fills. Realistic images are created by stippling, cross hatching and shading with additional options for pen tip size, coverage, and stroke length.
Snap Art Key Features

  • Canvas, paper and other media textures further enhance realism.
  • Lighting controls simulate the direction, intensity, and color of a light source.

User Interface
Below is a quick review of the main features of the Snap Art user interface.

Menus (A) – Command menus are accessible within any filter. Macintosh users will see the menus in place of their usual menu bar. Windows users will see the menus at the top of the filter preview window.









Tabs (B) – Tabs with sliders, color swatches, check boxes, and radio buttons appear along the left side of the window. These controls perform most filter functions.



Render in New Layer (not shown) – This checkbox, introduced in Eye Candy 5, renders the filter image in a new, selected layer above the previous working layer. This makes non-destructive editing easier and faster.

Show Original Button (C) – Introduced in 2002, but with a facelift for Snap Art, this button toggles the preview window between filtered and unfiltered versions of the image. Click and hold this button to display the original image.

Split Screen Preview (D) – New in Snap Art, this menu gives the option to divide the preview in half, showing the filtered image in one half and the original image in the other.

Settings (E) – Settings are collections of slider values that can be recalled with a single click. Snap Art ships with hundreds of factory settings, which allow for one click effects. Users can also create settings to define their signature look.

Mouseover Help Text (F) – The bottom of the preview window offers instant help by listing a short comment or two that will pop up to the left of the progress bar and magnification indicator.
