How To Take Photographs With Your Computer
Chapter 4: Image Sizes and EditingWhen you get your image into the computer, you may need to resize it (for example, if you plan to use your image on the web, you will want to make sure it comes out at your intended size in people's web browsers) or perhaps even edit it.
As mentioned in the previous chapter, if you do plan on editing, it's best to use a lossless file format initially (such as BMP or PNG) and then (if you want) convert to JPEG only after your edits are all complete.
Computer images are measured in pixels which are dots on a computer screen. For example, many Microsoft Windows computers have a screen which is 800 pixels by 600 pixels.
However, when you take a picture with a scanner or digital camera, very often you will be asked to choose the size of the image in inches (or centimeters) and the resolution (measured in DPI - Dots Per Inch). You can convert this to pixels by multiplying the image size in inches by the resolution DPI.
If you want your photograph to appear larger or smaller on the computer screen, you could experiment with different resolution DPI settings. A lower DPI will result in a smaller picture on screen, and a higher DPI will result in a larger picture on screen.
If after, experimenting with different resolutions, you still can't make the image the correct size on screen, you could use good quality photo editing software to modify the image:
When you have a photograph in your computer, you will find that even a few relatively modest edits, using photo editing software can make for a massive improvement in the quality of the image. Furthermore, as you become comfortable with your photo editing software, you will eventually be able to use it to add sophisticated special effects to your photographs.
Aside from resizing, which we have already discussed, Some of the basic edits that you want to consider include:
