- 2. Try to identifywhich one is an IMAGE, a PHOTO, and a PICTURE. IMAGE PHOTO PICTURE
- 3. WHAT IS ANIMAGE?
- 4. An image isany visual object that's modified or altered by a computer or an imaginary object created using a computer.
- 5. Photo or photographis anything taken by a camera, digital camera, or photocopier.
- 6. Picture is adrawing, painting, or artwork created on a computer.
- 7. There are othervisual objects created on a computer that may fall into its own category, such as clip art, graphic, illustration, render, and a screenshot. When talking about any of these, we suggest using the proper terms instead of image, photo, or picture. In other words, if you're working with clip art, call it clip art instead of a picture.
- 8. An image/picture/photo can bein printed and digital copy. Digital copies are those that was created or copied and stored in electronic form.
- 9. Lets take afocus on images.
- 10. An image can alsobe described in terms of vector graphics or raster graphics.
- 11. Raster Image Raster (orbitmap) images are generally what you think about when thinking of images. These are the types of images that are produced when scanning or photographing an object.
- 12. Raster images arecompiled using pixels, or tiny dots, containing unique color and tonal information that come together to create the image. Since raster images are pixel based, they are resolution dependent.
- 13. The number ofpixels that make up an image as well as how many of those pixels are displayed per inch, both determine the quality of an image. As you may have guessed, the more pixels in the image and the higher the resolution is, the higher quality the image will be.
- 14. Vector Image Vector images,or line art, keep track of points and the equations for the lines that connect them. Generally speaking, vector images are made up of paths or line art that can infinitely scalable because they work based on algorithms rather than pixels.
- 15. One of thegreatest things about vector images is that you can re-size them infinitely larger or smaller, and they will still print out just as clearly, with no increase (or decrease) in file size.
- 16. Modern typography is almostexclusively created using vectors. The text you’re looking at right now is a product of vector graphics. 3D modeling and the computer graphics (CG) we see in blockbuster superhero films are the direct consequence of developments in vector art and illustration.

- 21. SVG Vector Image RasterImage JPEG Joint Photographi c Expert Group image .jpg, .jpeg, .jfif, .pjpeg, .pjp is a “lossy” format meaning that the image is compressed to make a smaller file. The compression does create a loss in quality but this loss is generally not noticeable. JPEG files are very common on the Internet and JPEG is a popular format for digital cameras - making it ideal for web use and non- professional prints. Scalable Vector Graphics .svg Vector image format; ideal for user interface elements, icons, diagrams, etc., that must be drawn accurately at different sizes.
- 22. WMF Vector Image RasterImage PNG Portable Network Graphics .png are a lossless image format originally designed to improve upon and replace the gif format. PNG files are able to handle up to 16 million colors, unlike the 256 colors supported by GIF. Windows Metafile .wmf WMF files are structured by a series of records, starting with a number of control records: the header record, the aforementioned optional placeable record, and finished by an end of file record.
- 23. EPS Vector Image RasterImage APNG Animated Portable Network Graphics .apng is a file format which extends the Portable Network Graphics (PNG) specification to permit animated images that work similarly to animated GIF files, while supporting 24-bit images and 8-bit transparency not available for GIFs. It also retains backward compatibility with non- animated PNG files. Encapsulat ed PostScript .eps file is a common vector file type. EPS files can be opened in many illustration applications such as Adobe Illustrator or CorelDRAW.
- 24. PDF Vector Image RasterImage GIF Graphics Interchange Format .gif files are widely used for web graphics, because they are limited to only 256 colors, can allow for transparency, and can be animated. GIF files are typically small is size and are very portable. Portable Document Format .pdf standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems.
- 25. CDR Vector Image RasterImage WebP Web Picture format .webp Excellent choice for both images and animated images. WebP offers much better compression than PNG or JPEG with support for higher color depths, animated frames, transparency etc. CorelDRAW .cdr is a vector graphics editor developed and marketed by Corel Corporation. It is also the name of the Corel graphics suite, which includes the bitmap-image editor Corel Photo-Paint as well as other graphics-related programs
- 26. AI Vector Image RasterImage BMP Bitmap Image .bmp is a format developed by Microsoft for Windows. There is no compression or information loss with BMP files which allow images to have very high quality, but also very large file sizes. Adobe Illustrator Artwork .ai is a proprietary file format developed by Adobe Systems for representing single-page vector-based drawings in either the EPS or PDF formats.
