The meaning of photo editing is the act of altering an image, simply put. But that’s oversimplifying a subject which is quite complex.

For example, some photo editing techniques are done manually, while others are conducted through automated software. Some photo editing is even done offline, on actual photographs, posters or other printed collateral.

Other terms for photo editing:

• Image editing
• Post-processing
• Image/photo manipulation
• Photoshopping
• Image/photo enhancement

There are many different types of photo editing. Some are simple and others are more complex. You can typically execute simple photo-editing techniques fairly easily and quickly. Complex techniques and digital editing may require a software program and more experience and training.

Simple photo-editing techniques include:

1. Noise reduction: smoothing the picture out, typically accomplished by reducing the pixel size
2. White balance: the color of the light in the image
3. Contrast: higher contrast makes an image more punchy, while lower contrast makes it flatter in color
4. Exposure: the brightness of the photo
5. Lens correction: addresses any issues with the camera lens
6. Color adjustments: change the color of an item or element in the photo
7. Resizing and cropping: adjust the dimensions of the image
8. Background removal: delete the background from the image, isolating the subject (this is often used for white background product photography)
