Consejo

If you are not interested in technical details, a good rule of thumb for selecting output formats for your project is:

Usar OpenEXR: if you intend to do compositing or color grading on these images.
Usar PNG: if you intend on-screen output or encoding into multiple video formats.
Usar JPEG: for on-screen output where file size is a concern and quality loss is acceptable.

All these formats support compression which can be important when rendering out animations.

Consejo

Bit depths for image formats represent the following numbers of tonal levels per channel:

8:: 256 niveles
10:: 1024 niveles
12:: 4096 niveles
16:: 65536 niveles

Apertura de imágenes#

Rutas relativas

Sets the file path to be relative to the currently opened blend-file.

Ver Rutas relativas.

Detección de secuencias

Busca automáticamente secuencias de imágenes en las imágenes seleccionadas (según el nombre del archivo). Deshabilítelo cuando desee obtener imágenes individuales que formen parte de una secuencia.

Detección de UDIM

Busca automáticamente celdas UDIM en el directorio de la imagen seleccionada; si se encuentran coincidencias, se cargan en Blender como UDIM. Esto funciona al detectar si el nombre del archivo tiene un .xxxx (número de cuatro dígitos) antes de la extensión del archivo.

Apertura de una secuencia de imágenes#

To load image sequence in any of the supported image file formats, the filename of the images must contain a digit to indicate the frame order (e.g. *-0001.jpg, *-0002.jpg, *-0003.jpg, etc, of any image format), indicating the frame.

The sequence could be opened by the selection of the images with any of the following methods by the confirmation with the Open Image button or Return.

Rango: Navigate into the directory and LMB click and drag over a range of names to highlight multiple files. You can page down and continue Shift-LMB click-dragging to add more to the selection.
Lotes: Shift-LMB click selected non-related stills for batch processing; each image will be one frame, in sort order, and can be a mix of file types (jpg, png, exr, etc.).
Todo: Press A to select/deselect all files in the directory.

Guardado de imágenes#

Formato de archivo

Choose what format to save the image as.

Modo de color

Choose the color format to save the image (or video) to. Note that RGBA is not available for all image formats, check the list above for details.

BW, RGB, RGBA

Profundidad de color

Some image file formats support a varying number of bits per pixel. This affects the color quality and file size. Commonly used depths:

8 bits:: Most common for on-screen graphics and video.
10, 12, 16 bits:: Used for some formats focusing on photography and digital films (such as DPX and JPEG 2000).
16 bits media decimal:: Since full 32bit float is often more than enough precision, half float can save drive space while still providing a high dynamic range.
32 bits decimal:: Highest quality color depth.

Nota

Internally Blender’s image system supports either:

8 bits por canal (4 × 8 bits).
32 bits decimales por canal (4 × 32 bits) – usa 4 veces más memoria.

Images higher than 8 bits per channel will be converted into a float on loading into Blender.

Compresión

Used to reduce the size of the image file. How this is done may vary depending on the file format and settings used.

Calidad

Similar to Compression but is used for JPEG based file formats. The quality is a percentage, 0% being the maximum amount of compression and 100% is no compression.

Save As Render

Save image with render color management. For display image formats like PNG, apply view and display transform. For intermediate image formats like OpenEXR, use the default render output color space.

Copiar

The Copy checkbox will define if the data-block will reference the newly created file or the reference will be unchanged, maintaining it with the original one.

Espacio de color

Para especificar el espacio de color del archivo de origen.

La lista de espacios de color depende de la Configuración OCIO activa. Los espacios de color compatibles predeterminados se describen en detalle aquí: Configuración predeterminada de OpenColorIO

Nota

Note, Cineon, DPX, OpenEXR, and Radiance HDR image types default to being saved in a linear color space.

Detalles de formatos#

Cineon y DPX#

Cineon is Kodak’s standard for film scanning, 10 bits per channel and logarithmic. DPX has been derived from Cineon as the ANSI/SMPTE industry standard. DPX supports 16-bit colors/channels, linear as well as logarithmic. DPX is currently a widely adopted standard used in the film hardware/software industry.

DPX as well as Cineon only stores and converts the «visible» color range of values between 0.0 and 1.0 (as a result of rendering or composite).

OpenEXR#

ILM’s OpenEXR has become a software industry standard for HDR image files, especially because of its flexible and expandable structure.

An OpenEXR file can store multiple layers and passes. This means OpenEXR images can be loaded into a Compositor keeping render layers and passes intact.

Opciones de salida#

Available options for OpenEXR render output are:

Profundidad de color

Half saves images in a custom 16 bits per channel floating-point format. This reduces the actual «bit depth» to 10-bit, with a 5-bit power value and 1-bit sign.

Float (Half), Float (Full)

Compresor

PXR24:: Lossy algorithm from Pixar, converting 32-bit floats to 24-bit floats.
ZIP:: Standard lossless compression using Zlib, operating on 16 scanlines at a time.
PIZ:: Lossless wavelet compression. Compresses images with grain well.
RLE:: Run-length encoded, lossless, works well when scanlines have same values.
ZIPS:: Standard lossless compression using Zlib, operating on a single scanline at a time.
DWAA:: Algoritmo lossy similar al JPEG de DreamWorks; comprime bloques de 32 líneas de exploración juntas.
DWAB:: El mismo que DWAA pero comprime bloques de 256 líneas de exploración.

Previsualización

On rendering animations (or single frames via command line), Blender saves the same image also as a JPEG, for quick preview or download.

Radiance HDR#

Radiance is a suite of tools for lighting simulation. Since Radiance had the first (and for a long time the only) HDR image format, this format is supported by many other software packages.

Radiance .hdr files store colors still in 8 bits per component, but with an additional (shared) 8-bit exponent value, making it 32 bits per pixel.
