Range Of Image Types Available Technology Essay Example

by the Joint Photographic Experts Group and uses file extensions .jp2 and .j2k. BMP (Bitmap Image File), introduced by Microsoft for Windows operating systems, tends to have larger file sizes compared to JPEG files due to the absence of lossy compression. According to The Sheridan Group (2001), electronic image files are formats based on pixels that support RGB color space and different levels of depth per channel. GIF (Graphics Interchange Format), developed by CompuServe in 1987, is widely used on the internet due to its small size of only 8 bits. It is commonly used for icons and can include animations like banners or short videos. GIF uses lossless compression, reducing file size without compromising quality. Another format called Exif is utilized by digital cameras, scanners, and smartphones such as Android. RAW is an unprocessed image file resembling a photo negative.On the other hand, PNG (Portable Network Graphics) was created as a patent-free alternative to GIF, offering improvements in terms of features while eliminating the need for a patent license.WEBP is a new image format developed by Google with the purpose of reducing loading time on web pages. It achieves this by allowing for smaller image files while maintaining quality, resulting in faster web browsing.

Vector artworks differ from raster artworks in that instead of dividing an image into pixels, they use instructions to recreate it. According to June Parsons (2008), vector artworks have storage advantages but require more storage space as each instruction needs its own. However, they generally require less storage space overall and can be resized better than raster artworks.

The most popular vector file formats are Computer Graphics Metafile (CGM), Portable Document Format

(PDF), and Scalable Vector Graphics (SVG). CGM is widely used in computer-aided design applications and is an International Standard format. SVG, developed by the World Wide Web Consortium (W3C), is still under development and does not charge royalties as it is a royalty-free vendor format according to W3C (2004). It consists of an XML-based file format and a programming interface for graphical applications, serving as a platform for planar graphics.The PDF file format is known for its key features including forms, text, and embedded raster artworks. These files are widely used online to display various types of documents such as tax papers, menus, brochures, and instructions. When viewed online using Adobe Reader, PDF files maintain the original appearance of the paper document and can include images, forms, outlines, and other data.

On the other hand, CDR is a vector file format specifically designed for Corel Draw graphics suite. It can only be accessed with Corel software. ODG is a diagrammatical document format used with open office products that are freely available.

Now let's discuss the first image being described which is a landscape image of an area on Preston campus. To improve this image from its original state, I performed several enhancements such as repairing the scenery and removing unnecessary parts. Additionally, I added laser effects to create an illusion of a rainbow emerging from the street lamp. Throughout the design process of this image, I made sure not to overcrowd the beds but instead used more beds to clearly explain each bed's content.

In terms of layer steps:
Layer One represents the original landscape image prior to any changes.
In Layer Two, I cleaned up the path

around the station box and road area by removing litter and gum to give it a cleaner look.
In Layer Three, I enhanced the condition of the station box and poles by repairing any damage, such as a dent in one of the poles. Additionally, I utilized the healing brush to tidy up the path and replaced worn-out tarmac with fresh-looking material. Shifting to Layer Four, I restored faded road markings and completely repaired the road surface to eliminate any dust present. Furthermore, I made some compositional changes by removing a person and a lamppost that didn't harmonize well with the overall image. I recreated their original areas where they were situated. Lastly, for aesthetic reasons, I repainted and eliminated a dirty window from the white building since it didn't align with my desired vision for the image.

From Layer Six until Layer Thirteen is where Image Transformation occurs. Utilizing an RGB input/output adjustment bed called "RGB input/output adjustment," I modified the curves of the image to achieve a warm and full expression. To infuse happiness and cheer into the picture, I employed seven beds to create a rainbow effect emanating from the featured lamppost. The decision to use seven beds corresponds to there being seven colors in a rainbow. Each bed on the fourteenth layer enabled me to manipulate shadows, freshness, opacity, and other effects using blend options. This was done in order to make final adjustments to enhance overall brightness and contrast of the image while adding finishing touches for its completionThe purpose of creating this image was to depict a clean and fresh area surrounding a university. To achieve this, I made enhancements, cleaned

up the image, replaced elements, restored parts, and repaired any issues. These improvements were done to make it resemble a newly constructed building with freshly tarmacked roads and other enhancements. The resulting image successfully accomplishes my objective of looking enhanced, clean, and fresh. It is undoubtedly a significant improvement over the original.

In the second image, I focused on creating a still life featuring a mobile phone. I cropped the phone from one of my pictures and placed it on a different background that I created specifically for this purpose. The goal was to create an image suitable as a screensaver showcasing a handheld device functioning as a mini portable computer. To achieve this effect, I utilized various effects such as smoke backgrounds, threaded lasers, fuzziness adjustments, chromatic alterations, and custom wind-designed text. Additionally, I added the phone image to the main image using seven layers in total during its creation.

Below is an elaborate explanation of each layer's process:

Layer Steps:

Layer One: For the first layer background color choice, black was selected.

Layer Two: On top of the black background from Layer One,
four large faded red circles were added by utilizing
a large brush tool with 65% hardness along with 100% opacity
and flow settings.

(Note: have been used for formatting purposes)

Layer Three:

The next step involved adding a cloud effect on top of the previous layers, resulting in reddish clouds.

Layer Four:

Next, I added the phone image as the focal point. To make it stand out with a neon glow against the old bed background, I made modifications such as drop shadows, inner shadows, outer glow,

and inner brightness. Additionally, I changed its coloring to create a neon line using the pen tool and an outer freshness effect. Text was also added to match the overall appearance.

To create an illusion of wind passing by, a wind effect was applied. The interior color was red to fit with the theme while a white shadow effect enhanced visibility around the text. Lastly, another layer adjusted brightness and enhanced colors for vibrancy in the final image.

Image Justification

The purpose of creating this still life screen saver image was to demonstrate various computing-related skills and depict a universally relatable item. To achieve an attractive appearance, the image needed to be shiny, colorful, and unique. This goal was accomplished by enhancing the phone image and creating a custom background that aligned with my vision. With this successful creation of an entirely new background from scratch while modifying the phone image and utilizing text elements.

Image Three

The third image solely focused on portraying myself.

Initially, I removed the background content of the original image to create a black backdrop. Then, I superimposed another image onto mine to achieve a dark and eerie visual by applying a color burn effect. To accomplish this effect, I utilized various tools such as color burn, burn tool, black and white, fuzz, and blend. Additionally, I made edits to enhance facial appearance by eliminating facial hair and fixing imperfections. In particular, for the black and white image, I changed the eye color from brown to red in order to make them stand out. This fourth layer was designed with efficiency in mind using only four layers.

Below is a detailed description of the modifications made to

each layer in Adobe Photoshop CS5:

- Converted the first layer into black and white. Removed facial hair and imperfections while adding more head hair for a thicker look. Used the burn tool and shadow tool to age and darken the image.

- Altered eye color to red for contrast against the black and white background. Made adjustments to the bottom left and top right corners of the image's background (these changes were performed in Layer Three).

- Merged an image of clefts with the main image using the color burn effect. Removed any unnecessary clefts from areas other than the face and neck.

- Applied blood under the eye and on mouth using a low hardness paint tool.The purpose of creating this third and final image was to showcase my ability in creatively manipulating different tools within Photoshop, with the specific intention of creating a dark and scary atmosphere. I achieved this by exclusively utilizing red, black, and white colors. This unique creation possesses a chilling effect while demonstrating my skills in transforming an individual's appearance into something eerie.

In this review, I will evaluate the enhanced capabilities of this version of Photoshop compared to previous versions. Additionally, I will briefly discuss three alternative options in order to assist you in making an informed decision when purchasing Photoshop.

One notable feature is content-aware, which allows you to remove objects and create background fills using surrounding data. While easy to learn and use, not all images yield optimal results with this tool. Abstract images with clear forms tend to work well as the content-aware tool utilizes surrounding information to fill in missing

details after object removal.

In my testing on three different images, this tool proved excellent except for instances where there were many people, trees, and other scenery around the object.

Another new tool in Photoshop CS5 is edge sensing found within the refine edge dialog box. This feature aids in handling problem areas like hair when cutting out an object from one image and placing it into another.In my opinion, this tool is excellent because it greatly reduces the time needed for small edits on objects. For instance, editing hair used to take about 20 minutes without border sensing capabilities, but with the border sensing feature, it would only take around two minutes. Border sensing in Photoshop CS5 seamlessly integrates the image with a new background, which is a significant advantage. While it may not work well for every image, it remains a valuable feature. Another useful tool in Photoshop CS5 is the puppet wrap command, allowing manipulation of an image by creating adjustable pivot points. However, when using this tool, it's important to keep edits simple to avoid making the object look unrealistic and ruining the overall image.

The main drawback of Adobe Photoshop CS5 is its high price of ?657.60 for the standard edition according to the Adobe website. This steep cost may discourage casual users from purchasing the product. Nevertheless, if you are using Photoshop for work purposes, it might be worth investing in due to its long-standing reputation and consistent release of excellent software.

For those seeking an alternative to Photoshop at no cost,GIMP stands out as a free option that appeals to both amateurs and professionals alike due to its affordability.Being open-source,GIMP offers many

functionalities similar to those found in PhotoshopOne notable difference lies in its interface – while some users prefer it, others do not share the same sentiment regarding having toolbars outside the main window (Cardoso, 2010). GIMP is compatible with major operating systems and has been adopted as the default image program by many Linux distributions. However, Ubuntu discontinued its use of GIMP because they believed it was too powerful for standard desktop users. Another option is Krita, which is part of the Koffice suite and also free like GIMP. Krita has gained popularity among those interested in creating studies, sketches, and concept art pictures. It offers a user-friendly and easy-to-use experience but lacks some of the main features found in more popular software packages such as Photoshop. Nonetheless, you can still create and edit compelling images using Krita since it provides unique features that other free software does not have, like pluggable brush engines.

Corel's Paint Shop Pro Photo X2 is another competitor to Photoshop. Corel has a longstanding presence in the industry that ensures their product maintains high standards. One advantage of Paint Shop Pro over Photoshop is its lower price at around ?45, offering great value considering the abundance of tools and features it contains. Additionally, Paint Shop Pro includes an intriguing tool called photo aging that allows users to apply an aging filter to their images for a vintage movie look.The "Time Machine" feature enhances images by allowing users to choose different time periods from the past to enhance their appearance. I have explored various image types and discussed important information about file formats, including size, quality, uses, and other relevant details. Additionally,

I have explained the steps taken to create the images and provided a brief explanation for each image's rationale, along with the tools and methods used. The purpose of this was to demonstrate my ability to edit and create images using a wide range of Photoshop tools that would produce optimal results for my final three images. In addition, I evaluated Adobe's latest release, Photoshop CS5, highlighting its key features while acknowledging its cost as a drawback. Furthermore, I examined three alternative options for image editing software and discussed their unique features and tools. My objective was to assist readers in making an informed decision about which software would best meet their needs.
