Principles and Basic Techniques of Image Manipulation

Image manipulation, or photo editing, is the process of altering an image using software to achieve a desired effect. It can range from simple adjustments like cropping and color correction to more complex techniques like compositing and retouching.

Principles of Image Manipulation

  Preservation of Quality: Always strive to maintain the original image quality as much as possible. Avoid excessive manipulation that can lead to pixelation or artifacts.

  Harmony with Content: Any changes made should complement the original image and enhance its overall message or aesthetic.

  Ethical Considerations: Be mindful of ethical implications when manipulating images. Avoid altering images in ways that could be misleading or harmful.

Basic Techniques

1.         Cropping: Removing unwanted portions of an image to focus on the subject or improve the composition.

2.         Resizing: Changing the dimensions of an image to fit specific requirements or display formats.

3.         Rotating: Adjusting the orientation of an image to correct any tilt or to achieve a desired effect.

5.         Sharpening: Enhancing the edges and details of an image to make it appear more defined.

6.         Blurring: Softening the focus of an image to create a dreamy or ethereal effect.

7.         Layers: Working with multiple layers allows you to manipulate different elements of an image independently without affecting the others.

8.         Compositing: Combining multiple images to create a new scene or effect.
