While saving a native Luminar file is important, you may also need to export multiple files for other tasks. Maybe it’s to post online, to drop into a presentation, or to collaborate with others.
When you export a file, you can save in a variety of file formats including JPG, TIFF, PNG and even PSD. Each file format has its own unique set of parameters which are standard macOS system options.
Saving an Image File.
Sharpen. Choose whether you want to Sharpen the exported file. This can increase details in the edges of the image and overcome some of the compression artifacts of formats like JPEG.
Resize. You can choose to export at the original size, or to enter a new dimension for the image to fit its long side or short side.
Color Space. You can choose from 3 color spaces for output. sRGB is the narrowest color gamut, but most compatible with the web. Adobe RGB is a common color space used in computer graphics and many software applications. ProPhoto RGB is the widest gamut and supports the broadest range of colors. ProPhoto RGB is the only color space that can contain all the colors captured in a raw format photo.
Format. Choose from eight different file formats. Some options like TIFF and JPEG may offer additional settings for control over compression and bit depth.
Give the file a descriptive name and click the Save button to write to disk.
The following types of file can be created in Luminar.
JPEG (.jpg) – The Joint Photographic Experts Group (JPEG) format is most often used to display continuous-tone images (such as photos) on the Internet. Most digital cameras use JPEG because it provides excellent compression; the maximum setting provides comparable image quality to much larger file formats like TIFF. Occasionally, the print industry (especially newspapers) will use JPEGs.
JPEG is a lossy compression, which means that some data is discarded during compression of the image. JPEGs should not be used as an archive or production file format. You should generally only save JPEG files once, because re-saving continues to discard data and lower image quality. If you have acquired an image as a JPEG in your camera, be sure to save the edited document as a native Luminar file.
PNG (.png) – The Portable Network Graphics format provides lossless compression. It is increasingly common on the Internet, as most web browsers support it. The PNG format was created to be a patent-free alternative to GIF. Its major advantage is the PNG-24 file, which allows for 24-bit images (8 bits per channel) and embedded transparency. It is technically superior to GIF.
GIF (.gif) – The online service provider CompuServe originally developed the Graphics Interchange Format (GIF). This format displays 8-bit or indexed-color graphics and images in HTML documents on the Internet. You’ll hear the file called both “giff” and “jiff”; both are acceptable.
GIFs use a color table (with no more than 256 colors total, not per channel) to represent the image. This can lead to a small file size but also banding in the image. In most cases a JPEG is a better option for web delivery.
TIFF (.tif) – The Tagged-Image File Format is one of the most common and flexible formats available. It is widely used to exchange files between applications and computer platforms, and has a long legacy of compatibility. Additionally, TIFF is one of the formats to work in a bit depth of 8 or 16 bits per channel.
JPEG 2000 (.jp2) – The JPEG 2000 format is an update released in the year 2000 from the Joint Photographic Experts Group committee. Its intent was to replace the original JPEG format. It uses a newer wavelet-based method of image compression which is more efficient.
Photoshop (.psd) – The Photoshop format is a common format used in the computer graphics industry. Macphun cannot write a layered file, but can export a file that can be opened by Adobe Photoshop and other software packages which support the format.
PDF (.pdf) – The Portable Document Format (PDF) is a file format invented by Adobe and was intended to be an extension of PostScript. A PDF can be viewed on virtually every operating system and portable media player or phone.
The PDF is an open standard, which means that the computer industry is able to create applications that can read or write PDFs without paying Adobe additional fees. This openness led to the quick adoption of PDF, and it is utilized online extensively.
