The best practice when doing Chroma Key photography and/or video is to use a solid color background such as a green screen or a blue screen when shooting your subject. After the image has been captured, the solid colored background is removed and made transparent, and a replacement background is then added giving the impression that the subject was at a different location, or a much preferred background is then added.
“Why use a green screen or a blue screen” you may ask. Because separating a background from a human subject in a photo or video is much easier if the background is made of a solid color which is not found in human skin tones, like the colors green and blue. There are other precautions that need to be taken when shooting Chroma Key. The subject that is being photographed or video recorded must have contrasting colors compared to the background. If you are using a green screen, you do not want your subject be wearing anything that has any shade of green. If the subject is wearing a green T-shirt and you are using a green background, the only thing that will show up is the subject’s arms in their head.
Images often account for most of the downloaded bytes on a web page and also often occupy a significant amount of visual space. As a result, optimizing images can often yield some of the largest byte savings and performance improvements for your website: the fewer bytes the browser has to download, the less competition there is for the client's bandwidth and the faster the browser can download and render useful content on the screen.
Image optimization is both an art and science: an art because there is no one definitive answer for how best to compress an individual image, and a science because there are many well developed techniques and algorithms that can significantly reduce the size of an image. Finding the optimal settings for your image requires careful analysis along many dimensions: format capabilities, content of encoded data, quality, pixel dimensions, and more.
Optimization of any and all graphics and a website is very important. If images are not optimized, they take longer to load in a browser window and. Most people are impatient when it comes to image load time and quite often they will just close the web page out,, and go to a different website.
