It seems that there are blogs for every subject.
In filmmaking, a technique known as Matte Shot is used to fill in the background of a scene whether this is a city or a landscape. Some amazing work goes into these matte paintings for only a few seconds of screentime.
Check out Matte Shot - a tribute to Golden Era special fx:
This blog is intended primarily as a tribute to the inventiveness and ingenuity of the craft of the matte painter during Hollywoods' Golden Era. Some of the shots will amaze in their grandeur and epic quality while others will surprise in their 'invisibility' to even the sophisticated viewer. I hope this collection will serve as an appreciation of the artform and both casual visitors and those with a specialist interest may benefit, enjoy and be amazed at skills largely unknown today.
Just keep scrolling down - some gorgeous work...
