CÁMARAARRI ALEXA

Juan Carlos Rosero

RESOLUTION

• ALEXA has a 3.5K CMOS Imager yielding either a 2K or 1920 X 1080 HD image.  Becase of ALEXA's use of the continuously improving ARRI Imaging Technology (AIT), images are sharper and cleaner than other cameras that claim 4K+ resolution.

AIT

• The amazing filmic look of images shot with the ALEXA and ARRIFLEX D-21 is the result of a custom designed CMOS sensor, an optical low pass filter, a powerful imaging hardware engine, and advanced image processing algorithms. The innovative orchestration of all these proprietary components is ARRI Imaging Technology(AIT).

AIT ADVANTAGES

• Provides super sharp, alias-free images through over sampling

• DPC guarantees that no single defective pixel will ever be visible

• Black balancing circuit automatically calibrates black level of each pixel in each frame

• Produces cinematic look and feel, high contrast and the highest dynamic range

• Most film like color reproduction of any digital motion picture camera

ALEV III SENSOR

• 800 EI BASE SENSITIVITY (200-1600)

• LOW NOISE

• 13.5 STOPS OF LATITUDE

• THE AFFORDABLE ROUTE TO TRULY CINEMATIC IMAGES

• 3.5K PIXEL COUNT PROVIDES OPTIMUM OVERSAMPLING FOR HD VIDEO AND 2K DI
