City Harvest "Apples", spot shot with iPhone
A spot recorded with an iPhone. This is the spot produced by an NGO that seeks to raise New York on the amount of food wasted in New York and the number of hungry in the city. Here are the piece:
Beneath the apparent simplicity that implies that this spot is recorded entirely with an iPhone, there is a substantial technological framework. The prestigious studio The Mill , responsible for the audiovisual work as detailed in its web was made this spot.
Indeed the base sequence shot of the spot was shot entirely with an iPhone in a New York subway station. Later in postproduction CGI should be incorporated in this case was the crowd of apples that come in an avalanche of wagons of the train. presente en toda la escena provocan una distorsión difícil de salvar por los softwares de tracking así que The Mill ideó un “rig”o armazón de cámaras , en cocreto tres Canon 5D MKII, que situadas fijas en la estación grababan sincronizadas en todo momento la posición del iPhone. For this integration was needed to make a tracking of the whole scene, which was quite difficult to do directly with the material recorded with the iPhone. The compression artifacts and the CMOS rolling shutter present in the whole scene cause a distortion difficult to save for tracking softwares so The Mill devised a "rig" or frame cameras, Canon 5D MKII cocreto three, which still placed at the station recorded synchronized at all times the position of the iPhone. This in turn was easy to locate by tracking software thanks to LED lights clearly marking its position in space. In this way the tracking is greatly simplifició although it was necessary to correct by hand, frame by frame as it happens almost always.
For realistic texturing apples used an HDRI map generated by a camera 360 ° x180 °, in particular a SpheronVR which also has an amazing 26f stops, camera any day deserve an article on this blog.
This whole process can be seen in detail in this "breakdown"
Finally, post-production to mimic the compression artifacts and color correction did the rest to provide that sense of realism.
So, yes, a spot shot with an iPhone, but there is more behind it to get that "look random" cinéma vérité.
