Basic concepts and terminology The Photoshop is a tool for photograph retouching, enhancing and will give you flexible features to produce stunning images which can be put in Web pages. If you have not fully understood the coloring of your images, you have go through the chapter on Basic Concepts. Basic Concepts What is computer graphics? There are two main types of computer graphics- vector and raster images. Vector images, such as those created in Adobe Illustrator, are made up of mathematically defined lines and curves called vectors. Raster images, such as those created in Adobe Photoshop, consist of a grid, or raster, of small squares, known as pixels. Several types of resolutions are important when working with digitized images. They …show more content…
Screen frequency is the resolution of the screen you will use when you print your final image. As a general rule, the image resolution should be twice the screen frequency to achieve the best printed results. To estimate scan resolution: 1. Multiply the longest dimension of the final image size by the screen frequency, then multiply this value by the ratio of the screen ruling (which is 2:1). Suppose you are now scanning an image that is 4 inches wide by 5 inches high. You are going to produce a final image that is 5 inches wide by 6 inches high. You are using a screen frequency of 150 lpi. 2. Multiply 6 (the longest output dimension) by 150 (screen frequency) to get 900 pixels. Then multiply 900 by 2 (the ratio of the screen). This equals to a total of 1800 pixels needed. 3. Divide the total number of pixels by the longest dimension of the original image. Here, the longest dimension of the original image is 5 inches. Dividing 1800 by 5 yields a scan resolution of 360 dpi. Importing images into Photoshop: The following image file formats are allowed: Photoshop 2.5 and 3.0 native formats, Adobe Illustrator, Amiga IFF and HAM, BMP, Compuserve GIF, EPS, JPEG, Kodak PhotoCD, Mac Paint, PCX, PICT file (raster only), PIXAR, Pixel Paint, Raw, Scitex CT, Targa and TIFF. Among the above file formats, some of them are
4 Make image on a full sheet of paper using exposure determined from test strip.
Screens: 5” and 7” does not have a substantial preference, although 10” screens size has doubled the odds.
Digital graphics are in their own way an art form, digitally constructed to create phenomenal images. However, you need to have some sort of artistic ability combined with a suitable computer system before you can design the perfect graphic.
"Drawn to scale" means a term that used to describe the delineation of distance and measurement on a drawing. E.g. "1/4 inch per foot" means that for each 1/4 of linear distance on the drawing is equivalent to one linear foot of real distance.
3. There are a couple of display options, scroll down the page until you see:
Another step in pre-processing is to make the image width and height divisible by 8. Let w and h represent the width and height of the image respectively. w and h are converted into w* and h* such that 8|w* and 8|h* are as follows in (1) and (2):
19. For a particular computer display, the screen resolution is set to 1280 x 1024. Which if the following is true about the term screen resolution, these two numbers, and what they describe?
Digital Camera: Images play an important role in the graphic images. It is like if there are no images then there cannot be any graphics. So to edit any graphic image you will need to have an image and to get image you need to have a digital camera which will let you capture anything you want so you can use that image to edit. There are variety of cameras available in the market from very cheap to very expensive but both of them does the same work. However, the cheaper one will not have enough clearer picture or the resolution so you can choose to buy a camera with a good megapixel and resolution which will make your work easier as you will get good images.
The first step was to acquire the equipment and materials needed in order to achieve measureable results. The three devices needed were an iPhone 6s, GoPro Hero 4, and a 4K video camcorder. In addition to these cameras, I used a tripod for the camcorder, and stabilized mounts for the iPhone and GoPro that attached to the tripod. I would also need a color card to measure color, and a poster with a few words on it to measure sharpness. Having access to the 4K TV in the Digital Media lab allows me to
I believe that photoshop is wrong, in which the photoshoper manipulates an image to make the person look worse. Also, I believe that it's wrong because they're making the image into somehting it isn't and that's the same thing as lying. In a March of 2014 article on BeautyRedefined.net, an image of Kelly Clarkson on SELF Magazine was photoshopped to make her look a lot thinner than she actually was. It was proved that the image was photoshopped when Clarkson appeared on Good Morning America just a few days later, and looked nothing like the image on SELF. Photoshopping an image is editing an image, thus making it a different

My method of editing is very light, I try not to crop, this is why I take 30 to 40 photographs on one subject matter and I keep the original raw photograph in a file. I have to edit my photographs in Photoshop because I take my photographs in color, just for that reason, some people like color better, I have to add contrast to achieve the depth in my black and white photographs.
Computer art usually refers to any form of graphic art or digital imagery that was created with the aid of a computer. Computer art which curators today call digital art or new media art started to emerge in the 1950 and focused mainly on geometric shapes in random combinations. Many critics at the time questioned whether computer art could in fact be called art. Critics wondered whether computer art could still convey concepts of “meaning”, “expression”, and “form”.
Businesses have countless applications for the computer software known as Photoshop. The software is such an integrated part of society that businesses and scholarly articles assume people have prior knowledge of what it is and what it does. Photoshop is defined by Oxford as trademarked digital image-editing software to alter photographic images. It is an industry standard for digital graphics and has many applications to various businesses and media. Lev Manovich wrote in Inside Photoshop that to count up the number of options in Photoshop and then count all the options each option subsequently contains, that the total number of options the software allows for would be in the thousands. Professionals in media, education, research, and many businesses utilize the software. However, there is controversy surrounding the use of Photoshop in advertisements that edited models to unrealistic levels, because of the impact those images have on society. Nonetheless, Photoshop is widely used and has revolutionized business and integrated into many industries not limited to media or photography.
It creates bitmapped images. Bitmap Images is one of many types of file formats for images stored in a programmed form. It carries the extension .BMP. Computers use bits of 1 and 0 to store data. A bitmap is literally a map of bits that form a particular picture when rendered to a display like a computer monitor. Adobe Photoshop is a well known program used by digital photographers around the world. The great quantity of Photoshop tips and tutorials make this a very easy program to learn and to use. Photoshop can be used to take any existing image and give it a professional, polished looked. Borders can be added and pictures tweaked to look better than any digital camera could make possible. Almost anything I can think of doing to a picture is accomplished when using adobe Photoshop. Bitmaps are much larger than vector file size and can lose quality when enlarged or reduced.
