Pixel-based images

Pixel-based images, also referred to as Raster graphics or Bitmaps a made up of small squares or dots known as pixels. A pixel (pixel-element) is the smallest editable element in a pixel-based image. A pixel-based image may be stored as a number of file formats such as a jpeg, png, gif, tiff or psd. Unlike Vector based imagery, pixel-based imagery is resolution dependent and can not be scaled up without loosing quality. Resolution is typically measured by the number of pixels per inch (ppi). The higher the number of pixels per inch the higher the image quality will be and the larger the file size will become. Each pixel in an image has a position on the document and an RGB value. By altering the RGB values and positions of various pixels in an image using a pixel editing program such as Adobe Photoshop, we can retouch and alter an image in a vast variety of ways. All digital photographs are pixel-based as are the majority of of images within a web page.

  4. In the Layers pallet choose Red from the channel menu.
  5. Slide the midtone slider to the left until the image appears noticeably red.  Let your eyes adjust to the colour for a moment then ease back the slider until the image does not look noticeably red anymore.
  6. Now choose Blue from the channel menu.
  7. Slide the midtone slider to the right until the image appears noticeably yellow.  Let your eyes adjust to the colour for a moment then ease back the slider until the image does not look noticeably yellow anymore.
  8. View the image before and after the adjustment by switching the visibility of the adjustnment onf and off. Make further adjustments as necessary. The image should not appear noticably red or yellow but should have a generally warmer appearance.

NOTE:  Most of the time the green channel will not need adjusting.
