Sketching Effect in Photoshop
These are what the original images look like:
Using the Filter > Artistic settings of Adobe Photoshop, I was able to make them look like painted canvasses. Cool, isn't it?

Tiger's Eye
Why tigers? Well, simply because I have this huge fascination about tigers. As for the fading effect, I used the paintbrush tool for the layer mask. It was easy. All I did was to paint the rough edges of the image so that it will somehow create a fading effect. For the background, I used the gradient tool. The leafy effect of the shadings was just a personalized brush of leaves painted on the background itself. Somehow, I enjoyed this activity.
So, what do you guys think of it? =]

What Is Adobe Photoshop?
Adobe Photoshop, or simply Photoshop, is a graphics editing program developed and published by Adobe Systems. It is the current and primary market leader for commercial bitmap and image manipulation, and is the flagship product of Adobe Systems. It has been described as "an industry standard for graphics professionals" and was one of the early "killer applications" on Macintosh.
Photoshop CS3, the current tenth iteration of the program, was released on 16 April 2007. "CS" reflects its integration with other Creative Suite products, and the number "3" represents it as the third version released since Adobe re-branded its products under the CS umbrella. Photoshop CS3 features additions such as the ability to apply non-destructive filters, as well as new selection tools named Quick Selection and Refine Edge that make selection more streamlined. On April 30th, Adobe released Photoshop CS3 Extended, which includes all the same features of Adobe Photoshop CS3 with the addition of capabilities for scientific imaging, 3D, and high end film and video users. The successor to Photoshop CS3, Photoshop CS4, will be the first 64-bit Photoshop on consumer microcomputers.Early History
In 1987, Thomas Knoll, then a PhD student at the University of Michigan, began writing a program on his Macintosh Plus to display grayscale images on a monochrome display. This program, called Display, caught the attention of his brother John Knoll, an Industrial Light & Magic employee, who recommended Thomas turn it into a full-fledged image editing program. Thomas took a six month break from his studies in 1988 to collaborate with his brother on the program, which had been renamed ImagePro. Later that year, Thomas renamed his program Photoshop and worked out a short-term deal with scanner manufacturer Barneyscan to distribute copies of the program with a slide scanner; a "total of about 200 copies of Photoshop were shipped" this way.
During this time, John traveled to Silicon Valley and gave a demonstration of the program to engineers at Apple Computer Inc. and Russell Brown, art director at Adobe. Both showings were successful, and Adobe decided to purchase the license to distribute in September 1988. While John worked on plug-ins in California, Thomas remained in Ann Arbor writing program code. Photoshop 1.0 was released in 1990 for Macintosh exclusively.
ReleasesContinual revisions were made to the program, with new versions released in the following years. In November 1992, a Microsoft Windows port of version 2.0 of the software was released, and a year later it was ported to the SGI IRIX and Sun Solaris platforms. In September 1994, version 3.0 was released, which introduced layers and tabbed palettes. In February 2003, the program shipped with the Camera RAW 1.x plug-in, which allowed the user to import RAW formats from different digital cameras directly into Photoshop.
In October 2004, the program was renamed Adobe Photoshop CS. The name uses the abbreviation CS for products in Adobe Creative Suite. The logo focused around a feather rendered in shades of blue and green, which was also used in 9.0. The 10th version, Photoshop CS3 was released on April 16, 2007, with a blue icon modeled after periodic table elements, matching the new icons of other Creative Suite products.
In January 2008, the Wine project announced official support for Photoshop CS2, allowing the Windows version of Photoshop CS2 to be used on Linux and other Unix platforms.
Photoshop is written in the C++ programming language.
FeaturesPhotoshop has strong ties with other Adobe software for media editing, animation, and authoring. Files in Photoshop's native format, .PSD, can be exported to and from Adobe ImageReady, Adobe Illustrator, Adobe Premiere Pro, After Effects, and Adobe Encore DVD to make professional standard DVDs and provide non-linear editing and special effects services, such as backgrounds, textures, and so on, for television, film, and the Web. For example, Photoshop CS broadly supports making menus and buttons for DVDs. For .PSD files exported as a menu or button, it only needs to have layers, nested in layer sets with a cuing format, and Adobe Encore DVD reads them as buttons or menus.
Photoshop can utilize the color models RGB, lab, CMYK, grayscale, binary bitmap, and duotone. Photoshop has the ability to read and write raster and vector image formats such as: .EPS, .PNG, .GIF, .JPEG, Fireworks, etc. It also has several native file formats:
- The .PSD (Photoshop Document) format stores an image with support for most imaging options available in Photoshop. These include layers with masks, color spaces, ICC profiles, transparency, text, alpha channels and spot colors, Clipping paths, and duotone settings. This is in contrast to many other file formats (e.g. .EPS or .GIF) that restrict content to provide streamlined, predictable functionality. Photoshop's popularity means that the .PSD format is widely used, and it is supported to some extent by most competing software.
- The .PSB (Large Document Format) format is a newer version of .PSD designed for files over 2 gigabytes.
- The .PDD (PhotoDeluxe Document) format is a version of .PSD that only supports the features found in the discontinued PhotoDeluxe software.
Photoshop CS3 is marketed with three main components of improvement over previous versions: "Work more productively, Edit with unrivaled power, and composite with breakthrough tools." New features propagating productivity include streamlined interface, improved Camera Raw, better control over print options, enhanced PDF support, and better management with Adobe Bridge. Editing tools new to CS3 are the Clone Source palette and nondestructive Smart Filters, and other features such as the Brightness/Contrast adjustment and Vanishing Point module were enhanced. The Black and White adjustment option improves users control over manual grayscale conversions with a dialog box similar to that of Channel Mixer. Compositing is assisted with Photoshop's new Quick Selection and Refine Edge tools and improved image stitching technology.
CS3 Extended contains all features of CS3 plus tools for editing and importing some 3D graphics file formats, enhancing video, and comprehensive image analysis tools, utilizing MATLAB integration and DICOM file support.
The logo comprises white letters "Ps" on a gradient blue square.

What Is Digital Imaging?
Basics of image editing
Raster images are stored in a computer in the form of a grid of picture elements, or pixels. These pixels contain the image's color and brightness information. Image editors can change the pixels to enhance the image in many ways. The pixels can be changed as a group, or individually, by the sophisticated algorithms within the image editors. The domain of this article primarily refers to bitmap graphics editors, which are often used to alter photographs and other raster graphics. However, vector graphics software, such as Adobe Illustrator or Inkscape, are used to create and modify vector images, which are stored as descriptions of lines, Bézier splines, and text instead of pixels. It is easier to rasterize a vector image than to vectorize a raster image- how to go about vectorizing a raster image is the focus of much research in the field of computer vision. People like vector images because they are easy to modify, containing descriptions of the shapes in them for easy rearrangement, as well as scalable, being rasterizable at any resolution- to rasterize a vector image is simply to render it, while scaling a raster image up involves guessing at data that isn't there, and even scaling a raster image down involves guessing unless the scaling factor is an integer.
Editing programs
Due to the popularity of digital cameras, image editing programs are readily available. Minimal programs, that perform such operations as rotating and cropping are often provided within the digital camera itself, while others are returned to the user on a compact disc (CD) when images are processed at a discount store. The more powerful programs contain functionality to perform a large variety of advanced image manipulations. Popular raster-based digital image editors include Adobe Photoshop, GIMP, Corel Photo-Paint, Paint Shop Pro and Paint.NET. For more, see: List of raster graphics editors.
Digital data compression
Many image file formats use data compression to reduce file size and save storage space. Digital compression of images may take place in the camera, or can be done in the computer with the image editor. When images are stored in JPEG format, compression has already taken place. Both cameras and computer programs allow the user to set the level of compression.
Some compression algorithms, such as those used in PNG file format, are lossless, which means no information is lost when the file is saved. The JPEG file format uses a lossy compression algorithm- The greater the compression, the more information is lost, ultimately reducing image quality or detail. JPEG uses knowledge of the way the brain and eyes perceive color to make this loss of detail less noticeable.
Image editor features
