Using High Key vs Low Key Lights
On this short video Daniel Norton from Adorama demonstrates the differences between high key and low key lights when shooting in a studio.
Many people think that high key lighting involves lots of light and a white background and although this might be true for most cases what Norton explains in this video is that high key actually refers to very low contrast image (so no shadows or almost no shadows at least). Low key lighting as you might expect has a lot more contrast and is typically used to add drama to your images or videos.
Technically speaking – high key will usually require more lights than low key images or videos which are also considered a bit more simpler to achieve technically (although both are very fundamental for any portrait photographer or videographer.
