History
In 2010, Apple introduced the iPhone 4—the first iPhone model with a front camera. It gave rise to a dramatic increase in selfies, which could be touched up with more flattering lighting effects with applications such as Instagram. The American photographer Cole Rise was involved in the creation of the original filters for Instagram around 2010, designing several of them himself, including Sierra, Mayfair, Sutro, Amaro and Willow. In September, 2011, the Instagram 2.0 update for the application introduced "live filters," which allowed the user to preview the effect of the filter while shooting with the application's camera. #NoFilter, a hashtag label to describe an image that had not been filtered, became popular around 2013.

An update in 2014 allowed users to adjust the intensity of the filters as well as fine-tune other aspects of the image, features that had been available for years on applications such as VSCO and Litely.

In 2014, Snapchat started releasing sponsored filters to monetize the participatory use of the application. In September 2015, Snapchat acquired Looksery and released a feature called "lenses," animated filters using facial recognition technology. Some of the early lenses available on Snapchat at the time were Heart Eyes, Terminator, Puke Rainbows, Old, Scary, Rage Face, Heart Avalanche. The Coachella filter released April 2016 was a popular early augmented reality filter.

'''In April 2017, Facebook released the Camera Effects Platform, which is the first augmented reality platform that allows developers to create their own filters and effects on Facebook's Camera. In December 2017, Snapchat also launched their Lens Studio augmented reality developer tool that allows users and advertisers to do the same on theSnapchat application. In April 2022,TikTok joined the two, and launched their own augmented reality developer platform called Effect house. '''

'''With the help of artificial intelligence and machine learning, filters have become much more realistic and seamless to the point where the use of filters can be undetectable at times. "Bold Glamour" is an example of a popular filter on TikTok released in 2023, that has the ability to change an individual's features features on video and completely change how they look. As AI usage becomes more accessible through filters, TikTok introduced a new feature that prompts users to label AI-generated photos and videos, along with a message stating that the content could be removed if users do not disclose AI tool usage.'''

Beauty filter
A beauty filter is a filter applied to still photographs, or to video in real time, to enhance the physical attractiveness of the subject. Typical effects of such filters include smoothing skin texture and modifying the proportions of facial features, for example enlarging the eyes or narrowing the nose.

Filters may be included as a built-in feature of social media apps such as Instagram or Snapchat, or implemented through standalone applications such as Facetune.

In 2020, the "Perfect Skin" filter for Snapchat and Instagram which was created by Brazilian augmented reality developer Brenno Faustino gained more than 36 million impressions in the first 24 hours of its release.

Critics have raised concerns that the widespread use of such filters on social media may lead to negative body image, particularly among girls.

Background
The manipulation of photos to enhance attractiveness has long been possible using software such as Adobe Photoshop and, before that, analogue techniques such as airbrushing. However, such tools required considerable technical and artistic skill, and so their use was mostly limited to professional contexts, such as magazines or advertisements.

By contrast, filters work in an automated fashion through the use of complex algorithms, requiring little or no input from the user. This ease of use, in combination with the increase in processing power of smartphones, and the rise of social media and selfie culture, have led to photographic manipulation occurring on a much wider scale than ever before.

One of the earliest examples of a content-aware digital photographic filter is red-eye reduction.

Effects
Typical changes applied by beauty filters include:


 * Smoothing skin texture; minimizing fine lines and blemishes
 * Erasing under-eye bags
 * Erasing naso-labial lines ("laugh lines")
 * Application of virtual makeup, such as lipstick or eyeshadow
 * Slimming the face; erasing double chins
 * Enlarging the eyes
 * Whitening teeth
 * Narrowing the nose
 * Increasing fullness of the lips

Beauty filters most frequently target the face, though in some cases they may affect other body parts. For example, the app "Retouch Me" was reported to have a feature which allows users to superimpose visible abdominal muscles (a "six pack") onto photos featuring the subject's bare stomach.
