Cropping and scaling: Cropping an image is when you choose to cut it down whether that be for: sizing reasons, getting rid of an unwanted part of the picture or to enhance meaning in the photograph. I may choose to crop the photographs I take for reasons such as these.
Scaling is similar to cropping as you alter the image but instead scaling solely resizes an image. You can choose to make the photograph smaller or larger but it may have an effect on the quality of the picture.
Green screen: I will definitely not be using green screen in my photography because of how difficult it would be both to hire and use, but green screening is very common in modern media. The subject will be photographed stood in front of a green (or blue) background and then in the editing stage the solid block of colour can be swapped for a separate photo to make the subject appear to be in a different location.
Layers: In photoshop you can add images on top of each other and this process is referred to as 'layering'. If you put a second image on top of the background picture parts of it can be erased to show the first layer, or the opacity can be changed so the layer beneath can be viewed. I could use the opacity technique in order to show my models in multiple poses or to show the stigma vs the true identity of the sub-culture.
Text and image: You can add text over an image in order to enhance the meaning of it. It might be a single word or a few lines that emphasise an aspect of the photo; if I wanted to I could write a sentence about the stereotyping of the sub-culture photographed but I feel this would ruin the mood of the images I am hoping to take.
