Q4 techniques employed to produce the context of images (everything outside the image) from beginning to the final presentation of the pictures

Magazine

Many magazines will frame the images on their pages. A lot of magazines will feature cropped images, or sometimes edited from the original so that certain parts of the image can be seen closer or even further away. 

Exhibition

The images at exhibitions are generally manipulated and not normally by the photographers who took the photos. Most of the images are put into frames but sometimes are left bare to show the true original image. Most of the galleries will have to produce space to make way for their presentations.
