Overview

Photo editing — also called image editing or image manipulation — is the deliberate alteration of a photographic image or other visual artwork to improve, correct, combine or change its appearance. Edited content can include digital photographs, illustrations and scans of analog film or prints. Edits range from modest corrections like exposure and color balance to creative compositing that produces an entirely new scene.

Common techniques and tools

Modern editing is often performed with software that works on raster images using pixels; common desktop and mobile programs provide layers, masks, brushes and automatic filters. Typical operations include cropping and straightening, exposure and color correction, sharpening, noise reduction, retouching blemishes, cloning, and advanced compositing using masks and layers. Raw photo processing and color management are important for photographic fidelity. Popular general-purpose and specialized tools include commercial and open-source packages and lightweight mobile apps; many users rely on well-known editors such as Photoshop and similar apps, free alternatives like GIMP, or simple programs such as Microsoft Paint and smartphone editors.

History and development

Before digital tools, photographers and illustrators altered images manually in the darkroom or with airbrushing and retouching on prints and negatives. With the spread of personal computers and graphic software in the late 20th century, many manual techniques were reproduced and expanded in digital form. Digital workflows introduced non-destructive editing (keeping original data intact), and powerful compositing, enabling both routine corrections and highly creative manipulations.

Uses and examples

Photo editing serves many fields and goals. Common uses include:

  • Publishing and advertising—retouching portraits, product photography and composites for visual impact.
  • Documentary and journalism—careful correction of exposure and color while preserving factual integrity.
  • Art and illustration—creating surreal images, digital paintings and mixed-media works.
  • Restoration—repairing damaged or faded historical photographs.
  • Scientific and technical imaging—enhancing contrast and detail for analysis.

Editing may also be used to alter appearances of people, such as professional model retouching, or to assemble composites for creative storytelling.

Ethics, accuracy and distinctions

There is a difference between routine correction and deceptive manipulation. In journalism and science, preserving context and disclosing edits are essential because alterations can mislead. In advertising and social media, heavy retouching has raised concerns about unrealistic beauty standards and consent. The term "photo manipulation" often implies a transformative or misleading change, while "photo editing" can mean routine technical adjustments.

Best practices

Practical guidance for responsible editing includes keeping original files, working non-destructively with layers or versioned files, embedding or preserving metadata, and applying color-managed workflows for consistent output. When edits affect meaning—such as removing or adding people or objects—clear disclosure maintains ethical transparency. Whether for restoration, visual storytelling, or technical analysis, careful documentation and respect for the subject and audience help ensure edits are useful and honest.
