Chromakey allows you to replace a background on digital photography and on video.with continuous video lighting, Blue or Green which is generally called blue screen or green screen can be used but its important that either light blue or light green is not on the subject as this could also be keyed out. Lighting the backdrop is important and that it is even and there are no shadows as this will be a problem for the keying software. We used imovie 11 for the keying but there are many other types of software that can do it. ▶ Check out my gear on Kit: https://kit.co/micso36 Follow us Instagram: @smickphoto @innerlightuk
