Technique Fill - Flash

Fill-Flash photography refers a method of taking pictures in which flash is used in bright light to flesh out details located in shadowy areas. Fill-flash is generally used in outdoor shots with full sun. Many cameras have a fill-flash mode that triggers the camera’s flash no matter how much light is available.
Fill-flash can also be used to increase the light of a shot that is backlit, making it again a way to reduce shadows. When you fear that your film will be underexposed, use fill-flash to enhance the amount of light the film captures. By adding light to a scene, the colors on the printed photo will be significantly brighter.

Technique Air Brushing

Air brushing refers to the photographic editing technique in which an image is retouched and smoothed over to improve picture quality. While air brushing has been done long before the advent of digital photography, digital imaging and editing programs, such as Adobe Photoshop, have made the use of air brushing much easier and more accessible to amateur photographers.
Although air brushing may be used in a various types of photography, it is most commonly employed in glamour photography, wedding photography and portraiture. For example, when a photographer wants to brush out the imperfections of a model’s face (e.g. acne or scars), he will air brush the image to make it appear smoother.
In particular circumstances, entire people or other details of a scene can be wiped out, altering the original image entirely. For this reason, documentary photographers and photojournalists alike heavily discourage and frown upon the implementation of air brushing in their respective fields. Similarly, any area of photography in which the integrity of the image is crucial to the resulting photograph will avoid air brushing or any other digital editing technique.

Model Release

Model Release is a legal document that serves as a contract between a photographer and his subjects. Photographers generally require that their models sign model releases to release the photographers from liability.
In a model release, the subject agrees to allow the photographer to use certain pictures. Depending on the terms of the model release agreement, a photographer may (or may not) be allowed to crop or manipulate the picture or use the picture in specific contexts. Similarly, some model release contracts may limit the number of times a photographer can use or publish the model’s photos.

In exchange for signing a model release, the photographer agrees to pay the model a certain amount. While model releases are most commonly used for human models, photographs of animals or private property also require that the owners sign a model release form. These contracts tend to be used most frequently in glamour photography for magazines and advertisements.
If the terms of a model release form are violated by either the model or the photographer, either side can file a lawsuit for breach of contract. If you are unaware of how to design a model release form or if you are unclear of the terms of a contract you are signing, consult legal advice before signing to avoid possible lawsuits.
