ARRI Textures 45
11 ARRI Textures
ARRI digital cameras have always had a ‘texture’ setting that is programmed into the way the sensor
captures images and subsequently bakes them (the images) into the ARRIRAW and ProRes outputs.
That texture setting, comprising many carefully balanced parameters, determines the amount of grain in
the image and the character of that grain. It also determines the amount of contrast at different levels of
detail in the image, which defines the perceived sharpness (technically called the MTF curve).
Up until now, ARRI cameras have been pre-programmed with a single, unchangeable texture setting
that is optimized for the widest possible range of shooting scenarios. The ALEXA 35 gives the option
to go beyond the default texture setting and choose from an evolving menu of ARRI Textures, each
designed for specific image attributes. This feature allows to fundamentally alter the way in which the
camera records images.
The camera comes with several ARRI Textures preinstalled, which can be selected similar to ARRI
Look Files. Like with ARRI Look Files, additional ARRI Textures can be loaded into the camera in
the future. There are ARRI Textures that increase grain and contrast for a more organic look; there
are ARRI Textures for shooting in low light, and so on. Since ARRI Textures are settings for image
processing steps that occur before the ARRIRAW image is created in the camera, ARRI Textures are
always baked into ARRIRAW and ProRes.
If a texture other than the K445 Default texture is to be used, it is very important for ARRI Textures to
be tested during preproduction, in the highest quality viewing environment possible. An ARRI Texture
that looks right in a DI suite or on a high end display will be very subtle or perhaps even invisible
when viewed in the camera's viewfinder or on the camera's SDI outputs. It is for this reason that we
recommend testing ARRI Textures in preproduction and viewing them on a large (at least 32-inch) high
quality UHD 4K monitor, ideally in HDR. Best practice is to view the images using an HDR 4K grading
display.
► Select MENU > Image > Texture > Texture to set the Texture.
Following options are available:
K445 Default The K445 Default texture is designed to work well for all subject matters and settings,
while making the most of the camera’s cinematic strengths. It is forgiving on skin, but al-
so renders images with exceptional clarity and detail, which makes it also a perfect tex-
ture for green screen shots. This is also the texture to use when shooting with ALEXA 35
and previous ARRI digital cameras, as it closely matches those cameras textures. Per-
fect for all EI settings.
P425 Cosmetic
A softer texture, very close to the cinematic K445 Default, especially recommended for
rendering skin tones. More forgiving on skin while keeping structures and highlights pro-
nounced. Low to moderate grain. Perfect for all EI settings.
G522 Soft Nostalgic A grainy texture with a subtle vintage feel, designed to render some unsaturated grain
and a softer character. Little softer vintage Texture than G733 Nostalgic. Perfect for all EI
settings.
G733 Nostalgic A grainy texture with a vintage feel, designed to render a lot of grain and a soft charac-
ter. The unsaturated grain type was created based on direct feedback from cinematogra-
phers. Perfect for all EI settings.
F567 Clarity A texture designed to work for any kind of footage, with increased sharpness and detail
compared to the K445 Default texture. The Clarity textures are a perfect choice for land-
scape shots. Works best for low to mid EI settings.
F578 High Clarity A texture designed to work for any kind of footage, with even more detail compared to
the K445 Default texture. The Clarity textures are a perfect choice for landscape shots.
Works best for low to mid EI settings.
