Manipulação de imagens digitais pelo cinema e televisão


Está imagem achei na internet, e não pude identificar o autor, mas achei interessante para ilustrar um breve comentário sobre o uso e a manipulação de imagens digitais no cinema e na televisão.
O cinema talvez tenha sido um dos setores que mais utilizaram os avanços tecnológicos em seu proveito, muitas vezes de forma experimental.
No final anos 80, início anos 90, diretor Sam Raimi introduziu a standy-cam, ou seja, uma câmera portátil, passível de ser levada a tiracolo, pelos mais acidenteados terrenos, sem que as imagens ficassem tremidas. Em tomadas alucinantes no meio da floresta, tinha um efeito incrível. O filme era por sinal Uma Noite Alucinante.
Os filmes, superproduções, ficaram mais baratos pelo uso da computação gráfica, com cenas maquiadas no computador. O filme Tron, da Disney, foi um precursor desses recursos eletrônicos, até que com a tecnologia introduzida na série Matrix, fizesse uma nova revolução. Gollum, da série O Senhor dos Anéis, um personagem totalmente digitalizado, e também um marco do cinema atual.
Na televisão a manipulação de imagens, ainda não é bem estudada. Percebesse mais nos anúncios comerciais e em algumas séries inovadoras, mas efeitos não tão acachapantes como os do cinema - tendo como referência Hollywood, evidentemente.
Mas pode-se perceber, através dos telejornais, em sua maioria, uma espécie de edição feita não em tom jornalísitco, mas mais cinematográfico, numa sucessão de cenas e notícias, com o intuito de prender a atenção do telespectador. Notícia é show? Ou deveria ser tratada como tal? Uma questão a ser pesquisada e problematizada futuramente...
Evidentemente que meu projeto de aprendizagem não irá se aprofundar em tais níveis, mas, de forma simples, procurará traçar o perfil da televisão, e como utilizá-la como aliada à educação.
