ARRI publishes an explanation of image sensor technology used in its cameras:

"Although the science behind the breakthrough performance of ALEXA's custom designed CMOS sensor is complex, the use of large photosites and a Dual Gain Architecture are its two main principles.

By employing unusually large photosites (in today's world of tiny cell phone sensors), ALEXA's sensor exhibits high dynamic range, high sensitivity and low crosstalk. The larger a photosite is, the more light it can capture and the lower the noise.

The Dual Gain Architecture simultaneously provides two separate read-out paths from each pixel with different amplification. The first path contains the regular, highly amplified signal. The second path contains a signal with lower amplification, to capture the information that is clipped in the first path. Both paths feed into the camera's A/D converters, delivering a 14 bit image for each path. These images are then combined into a single 16 bit high dynamic range image."

In advance of this year’s Tribeca Film Festival, Indiewire sent out brief questionnaires to all of the filmmakers (you can read their full answers in our Meet the 2015 Tribeca Filmmakers Series). As part of the questionnaire, we asked which camera(s) they shot on.

Their responses showed a wide variety of camera used – everything from drones to cellphones to the Swedish Ikonoskop, which is a digital camera meant to emulate the 16mm film look.

The most popular choices across the board were the ARRI ALEXA and RED Epic, as well as various models of Canon and Sony cameras. Almost all of the filmmakers produced their films digitally – the only films that specified having shot on film were "Franny," "Transfatty" and "Tumbledown."

We’ve arranged this master list alphabetically by camera – please note that some films used multiple cameras, so you’ll see a few repeats as you browse.

Does anyone have any insight into the best system to market my video?

Now with 4k coming along, I'm wondering if these older lenses will have any chance of producing the detailed images that the higher resolution sensors are capable of. Or, whether the way forward would be to use an RJ or Metabones speed booster with these lenses to get the detail/ resolution? It would be a shame to not be able to get the benefits of 4k unless using m43 lenses.

Does anyone have any experience, or opinions on this subject? I'd appreciate any comments.

This muddy "old" video is a mix of:

• A very personal/biographic collection of stills taken in Czech Republic, Spain and Portugal between 2006 and 2007

• Plus a tweaked version of Gertrude Stein's Family Living can go on existing a text extracted from her The Making of Americans book together with a shakuhachi flute (unfortunately can't remember neither song or performer's name) as SOUNDTRACK

• And still my own poem Algalia all mixed up directly in Quicktime

My main videos with most plays was the anamorphic project, neatvideo tutorial, super8 telecine tutorial, also lenses tests.

Please share your feedback about Tip Jar, did you get something?

and what do you think can motivate people to send Tip Jar to a video?
