Chroma key Photography Tips and Tricks - Computers - Software

Chroma Key photography refers to the process of digitally replacing the background image in a photograph with any other selected image. You also call it as Green Screen Photography. Photographers deploy this technique to create a unique and striking cinematography.

Techniques to add effects to photographs:

It is a fun loving activity to embellish your photographs with visual effects. A photographer should first photograph scenery that he wants to replace with the background of a subject. After you have collected quality pictures, you can now place your subject against the green or blue screen background in the studio. However, a photographer should ensure that the subject should not wear blue or green color used in the background. The foreground subject as well the background should have proper lighting. You can use light of around 250 to 600 watts. This is to avoid any kind of dark shadows on the face of a subject or dark spots on the background screen. A well-ironed background screen cloth properly masks the selected image at the background. A photographer should deploy a high quality camera that focuses a subject clearly. A clearly focused subject and background image makes a picture attractive. After taking the picture, you can then replace the background image digitally .A photograph can use overlay effects. To use overlay effects you need to capture and record an image. Edit the image and merge it with your photograph. Example, if you want to show your subject sitting in the midst of flowers, you can merge the picture of flowers around the subject. You can also make a subject invisible by covering his face with the cloth of a blue or green color that you use in the background. One can even make a person giant by making the buildings or other surroundings small digitally. A person can even use a cloning effect by taking two separate images of a subject. You can use the second image in the background in such a way so that these two images together give a cloning effect. There are many other effects that you can use with chroma key photography and make extensive use of creativity.
