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