Choosing file settings

You can control the output of your files. This includes several details about the generated files.

File Format

If you are working with an 8-bit image (such as a JPEG), you can choose to create

• TIFF – a TIFF using an 8-bit color that’s better for printing or further editing in another application.
• JPEG – a compressed web format that’s okay for printing
• PNG – A web-friendly format that’s less compressed

You can create higher-quality files if you are working with files that are 10- 12- 14- or 16-bit. These are usually DNG, raw files, or 16-bit TIFF.

• TIFF – Create a 16-bit TIFF from a raw file or 16-bit TIFF file.
• JPEG – Create just 8-bit JPEG files
• PNG – Create a 16-bit PNG from a raw or 16-bit TIFF file or an 8-bit PNG files
• Raw to TIFF, others to JPEG – Create 16-bit TIFF files from the raw photos and 8-bit JPEGs from others.
• Raw to TIFF, others to PNG – Create 16-bit TIFF files from the raw photos and 8-bit PNG from others.

If you are exporting JPEG files, you can assign a quality setting between 0–100. A value around 90 is quite effective for the web as it reduces file size and is visually lossless.

Color Space

You can export your image in one of three color spaces.

• sRGB is the narrowest color space but is most compatible with the web.
• ProPhoto is the widest gamut and supports the broadest range of colors. This is the only color space that can contain all the colors captured in a raw photo.
• Adobe RGB is a very common color space used in computer graphics and many software applications.
  

If batch processing, you can choose to use a combination of the Same as the original to match files that already have a color space (such as TIFFs and JPEGs) and assign a color profile to converted raw files.

Reduce Size

These settings let you reduce the file on export. This is useful if you have to transfer a file electronically or need to post to the Internet.

!Note: Radiant Photo does not change the pixel dimensions when saving the files unless you tell it to do so. The files are exactly the same dimensions. The JPEGs we produce are more optimized due to the image improvements and compression settings. There is no visible loss of quality here, nor are the dimensions changing.
