The History of Sound at the Movies
This is a sneak peak at a new audio course series

Subscribe to the Filmmaker IQ Youtube channel
FilmmakerIQ.com and RØDE Microphones are proud to give you a sneak peak at the first lesson in our six part course which will cover science/microphones, recording, editing, foley, and ADR. We are also hard at work behind the scenes updating the site to include even more interaction which should be live in the coming weeks. Until then - enjoy this lesson on the history of sound at the movies.
The inclusion of sound at the movies was one of the most dramatic changes in all of film history. Dive into the early experiments of Edison trying to incorporate sound from film's inception, through the experiments in the early 1920s, the Jazz Singer and the industry sound overhaul, and finally the multi-channel surround and modern movie sound technologies.
This video is proudly sponsors by RØDE Microphones.

Researchers Turn Everyday Objects Into Visual Microphones
The Visual Microphone: Passive Recovery of Sound from Video

Gautham J. Mysore, Fredo Durand, Wialliam T. Freeman
Published on Aug 4, 2014
Abstract: "When sound hits an object, it causes small vibrations of the object’s surface. We show how, using only high-speed video of the object, we can extract those minute vibrations and partially recover the sound that produced them, allowing us to turn everyday objects — a glass of water, a potted plant, a box of tissues, or a bag of chips — into visual microphones. We recover sounds from highspeed footage of a variety of objects with different properties, and use both real and simulated data to examine some of the factors that affect our ability to visually recover sound. We evaluate the quality of recovered sounds using intelligibility and SNR metrics and provide input and recovered audio samples for direct comparison. We also explore how to leverage the rolling shutter in regular consumer cameras to recover audio from standard frame-rate videos, and use the spatial resolution of our method to visualize how sound-related vibrations vary over an object’s surface, which we can use to recover the vibration modes of an object ~ Project Webpage"

Where Not to Fly Multirotor UAV's
This map only applies to US laws and regulations. This map doesn't include all the areas where drones are banned. Also note this information would be equally applicable for any RC Aircraft and NOT only for multirotors or "drones" as they are called in the media.

DIY Schlieren Flow Visualization Build
QUOTE: "Schlieren Flow Visualization is a method to see small differences in air pressure like those around a flame; essentially it allows you to *see* air. It is typically accomplished with super fancy mirrors that can cost upwards of $300. This instructable is about making a Schlieren Flow Visualization really cheaply and pretty easily. If you are curious about my failed attempts before I got it to work then visit my DIR Schlieren Flow Page ~ Jonathan Lansey"

History of the Mobile Camera

"Polaroids and Instant Cameras"
The first instant camera appeared in 1923, but it wasn’t until 1948 that such devices became popularized thanks to inventor Edwin Land. He called his instant camera the 'Land Camera'.
"Enter the CCD Chip"
In 1969 Willard Boyle and George Smith invented the CCD chip (charge-coupled device chip). This allowed for the birth of digital cameras but it wasn’t until 1981 a digital camera was introduced to consumers.
"The First Camera Phone"
The first Camera Phone only had 0.1 megapixels or 110,000 pixels for photos which cost consumers $500. Nevertheless Sharp's J-Phone as it so named was quite popular in Japan where it was introduced. America took notice and brought the technology to the US which soon after led to the camera phone battles.
"A Race for More Pixels"
The term ‘megapixel’ was introduced to consumers starting an arms race among producers we know as 'The Megapixel War (Google Search). In those early days more pixels did add to image quality however with diminished returns this thinking was going to change.
"Pixel Revolution"
As more pixels are crammed into the relatively same size sensor it meant smaller pixels. This increased the file size which allows for a larger printed image but added nothing to image quality. Manufactures soon realized that a bigger pixel means better image quality not more pixels. However the myth that more pixel equates to better image quality was locked into consumers minds. Only those who understood the technology knew full well this wasn't true for the newer large 'megapixel' cameras being manufactured.

Tony Northrup "Are Camera Manufacturers Misleading Us"
The following videos shown within the 'press' links, three in total, speak volumes but drew quite a few emotionally charged comments from it's distractors. Surprisingly the videos also drew heated comments from those who seemed to agree with Mr. Northrup. Nevertheless as entertaining and sometimes funny as the commentary these we're very informative videos that are well worth a look. Here we are showing the first video and it is the one which started all the fuss ...

Additional Reading: This article is also referenced in Tony's third video therefor to put into context I think it would be good to view that video before reading the following.
