Подсказка

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

Use OpenEXR: if you intend to do compositing or color grading on these images.
Использовать PNG: if you intend on-screen output or encoding into multiple video formats.
Use 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.

Подсказка

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

8:: 256 уровней
10:: 1024 levels
12:: 4096 levels
16:: 65536 levels

Открытие изображений#

Relative Path (Относительный путь)

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

See Relative Paths.

Detect Sequences

Automatically looks for image sequences in the selected images (based on the file name). Disable this when you do want to get single images that are part of a sequence.

Detect UDIMs

Automatically looks for UDIM tiles in the directory of the selected image; if matches are found they are loaded into Blender as UDIMs. This works by detecting if the filename has a .xxxx (four digit number) before the file extension.

Opening an Image Sequence#

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.

Диапазон (range): 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.
Batch: 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.).
Все (all): Press A to select/deselect all files in the directory.

Сохранение изображений#

Формат файла

Choose what format to save the image as.

Цветовой режим

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

Глубина цвета

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

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

Примечание

Internally Blender’s image system supports either:

8 bits per channel (4 × 8 bits).
32 bits float per channel (4 × 32 bits) – using 4 times as much memory.

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

Сжатие (compression)

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

Качество (quality)

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.

Сохранить как рендер

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.

Копировать (copy)

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.

Цветовое пространство (color space)

To specify the color space of the source file.

Список цветовых пространств зависит от активной конфигурации OCIO. Поддерживаемые «по умолчанию» цветовые пространства подробно описаны здесь: «стандартная конфигурация OpenColorIO».

Примечание

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

Format Details#

Cineon & 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).

Формат 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.

Output Options#

Available options for OpenEXR render output are:

Глубина цвета

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)

Codec

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:: JPEG-like lossy algorithm from DreamWorks; compresses blocks 32 scanlines together.
DWAB:: Same as DWAA but compresses blocks of 256 scanlines.

Предварительный просмотр (preview)

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.
