Here Are Some Quick Fixes "Reflective surfaces are a pain in the ass," said every filmmaker ever. Say you've just canned a glorious tracking shot. When you go to review the footage, however, you're dismayed to find out that you tracked past three windows, and in every single one of them you can see the dolly and camera crew, the boom operator, and some PA holding coffee that is wandering around like a lost puppy. Almost every filmmaker I know has dealt with this problem in some form or another, and it's one that every up and coming filmmaker will encounter at some point in their lives. But what can you do to get rid of those pesky reflections that can ruin your shots?

A Cheap & Easy Way to Create a Professional-Looking Infinite Black Backdrop Here's a cheap, simple, and professional-looking technique to add to your arsenal -- the infinite black background. Because its visuals add a level of surrealism and style, we've seen this used in music videos, dream sequences in narrative films, art films, you name it -- and chances are if you're not wondering how to pull it off, it's because your curiosity has already led you to find the answer. Filmmaker Lewis McGregor shares his insight into how to create this effect inexpensively and simply by using black material, three lights, and editing software. (No need for a huge soundstage!) If you're just starting out in filmmaking and haven't learned much about lighting and/or editing, then the technique McGregor uses is right up your alley -- especially if you don't have the cash or space, but need your project to look professional.

3 Isn't a Crowd, but You Can Make It Look Like It Is with These Cinematography Tricks What do wild parties, college lectures, massive armies, and zombie hordes have in common? If you're a filmmaker, they all require a ton of extras. But not everyone has a big enough budget or network to acquire them, which can be pretty stressful considering that at some point in your filmmaking journey, you're going to want/need to shoot a scene that requires a crowd. That's why it's crucial for every indie filmmaker to learn how to trick your audience into thinking that your five roommates (god help you) are actually a throng of wasted co-eds thrashing to EDM -- or whatever your scene calls for.

Most people I know don't do it, despite the clear benefits . It's more stuff to lug around, while your ever-ready phone offers literally hundreds of apps for speaking, writing, drawing, and syncing notes. So considering the use of multiple pen colors for your notes can seem a bit like lugging a Victrola around for a morning jog.

Spatial Agency - Connections map Christiania is an autonomous settlement on the site of a former military barracks in Copenhagen. After the military left the site it was fenced off but in 1971 a group of people took over parts of the site to make a children's playground. Soon after Christiania was proclaimed a Freetown with one of the original goals being to 'build up a society from scratch'. It is one of the largest 'slum communes' and was set up in direct response to the lack of affordable housing and social facilities, and as an antidote to stressful city life. The legal status of Christiania has been the source of much conflict with the Danish government and the fate of the settlement was a party political issue throughout the 1970s. However, Christiania was granted semi-legal status in 1972, following an agreement to pay a collective tax in return for water and electricity.
