What is the dynamic range of ARRI Alexa?

The self-contained ALEXA Mini can record UHD-resolution images with up to 14 stops of dynamic range. Its 35mm-sized CMOS sensor features a titanium mount and a 4:3 aspect ratio.

Do film cameras have better dynamic range?

A release by Kodak showcased that most film has around 13 stops of dynamic range. Today’s modern digital cameras all average around 14 stops of dynamic range, with high-end units such as the Nikon D810 reaching almost 15 stops.

What cinema camera has the best dynamic range?

If you really must have the bragging rights that comes with owning the highest-resolution video camera on the market, then the Blackmagic Ursa Mini Pro 12K is it. With a 79.6-megapixel CMOS sensor, it shoots 12K Blackmagic Raw files which give stunning quality with 14 stops of dynamic range and very filmic colours.

Is ARRI Alexa film or digital?

First introduced in April 2010, the camera was Arri’s first major transition into digital cinematography after smaller previous efforts such as the Arriflex D-20 and D-21. Alexa cameras are designed for use in high budget feature films, television shows, and commercials.

What is dynamic range of film?

In terms of photo and video, this is the range in which a camera can capture the brightest and darkest areas of an image without the loss of details in the image. If the camera moves beyond this dynamic range, then that’s when you’ll see the brights being washed out or the darks becoming noisy.

What is the dynamic range of a camera?

In photography, dynamic range is the contrast ratio between the darkest and brightest color tones that a camera can capture in a single exposure. Maximum dynamic range is the greatest range of light a digital camera sensor or strip of film can capture. Dynamic range is measured in stops.

What is film dynamic range?

Dynamic range refers to the range of which a camera can successfully capture the lightest and darkest areas of an image without losing detail. Once this range is exceeded, the highlights will wash out to white and the darks will turn to black blobs. So the higher the dynamic range, the better!

What makes ARRI Alexa the best?

Arri Alexas are not cheap, but they are only expensive out of the context of a fully-crewed commercial production where the familiarity and reliability of the equipment, and predictability and quality of the results, for most producers, pays for itself. Alexas have dominated the movie world and the high end of TV.

What is the dynamic range of the Arri Alexa?

Lucky for us the ARRI ALEXA factory dynamic range statement of 14 stops seems to correspond very well to the 0.5 = 1/ SNR equation as past cinema5d results showed, hence we will continue to use this threshold value to determine the dynamic range of different cameras.

The dynamic range of a camera can be simplistically defined as the ratio of the maximum and minimum luminance that a camera can capture. Sounds good, but how to quantify the term “capture”?

Is the Arri Alexa 2K or 3K?

The Arri Alexa, however, is right between the two with a base 2K resolution downsampled from a 3.5K sensor. Over the summer, Jim Jannard published resolution charts shot with both a prototype RED Epic and an Arri Alexa: No surprise to anyone there, RED has always found the pixel count to be an important spec in their cameras.

Are dynamic range charts useful for cinematographers?

Dynamic range charts are a lot of fun if you want to play games like “My camera’s dynamic range is bigger than yours!” but they don’t tell us how to exploit dynamic range in our work. My goal in these tests is to find how that dynamic range is distributed, which is much more useful to me as a cinematographer.
