The technique used to change green backgrounds with other backgrounds is known as chroma key technique. Since, in this technique, the green color has to be removed very accurately, so there are some points which need to be kept in mind. Firstly, there should not be any wrinkles on the green paper or muslin to be used as background. Secondly, there should not be any shadows falling on the screen. Lastly, the distance between the subject and the screen should be at least 7-8 feet.
After shooting, the photos have to be put one-by-one in green screen image editing software. Here, key out the green screen backdrop of the photos. Now, you are left with empty background where you can drop in another image background. Download required image backgrounds of beautiful buildings (such as Eiffel Tower, Angkor Wat, Chichen Itza, Taj Mahal, The Sydney Opera House, Statue of Liberty etc.) from the web. There are many sources online which provide the image backgrounds of many beautiful buildings which you can use as your photo backgrounds to make beautiful photos. The web also offers other image backgrounds, instead of buildings, which you can download to do wonderful photography. Download different image backgrounds to add life to your dull photos having plain green backgrounds.
