All Libris accounts can store image files. Depending on your subscription type, Libris can also store additional types of files and formats, such as video, audio, or other files.
Libris supports many image file formats, such as:
- JPG, JPEG
- TIFF, TIF
- Camera raw photos: most proprietary raw formats, such as CR2 and NEF, and any raw file converted to DNG
Libris offers more limited support for other image file formats, such as:
- PDF (particularly useful for loading license and rights contracts to their corresponding image Galleries)
- Font files, such as DFONT, OTF, and TTF
If your subscription offers video support, Libris can handle video formats such as MOV, MP4, and other common video file types from DSLR and other cameras or those created by video editing software.
Prepping for Upload
Preparing your files for upload to Libris requires considerations of file format, color space, and metadata.
Image File Format
Considerations of file format inevitably come down to understanding which format is appropriate for a given workflow stage. Although Libris can support a wide variety of file formats, uploading a format that is useful for your intended audience is a key consideration in creating a standard workflow. In many cases, Libris is used as a distribution/delivery tool. For this reason, JPG and TIFF are the most appropriate image file formats.
You can, of course, choose to archive your RAW (CR2, DNG) or PSD files within your Libris Library, but you would almost certainly never distribute these images to your stakeholders or customers.
PhotoShelter automatically creates multiple resized JPEG versions of every file you upload, so there is no need to upload multiple sizes of the same image.
Image Color Space
Computers use a series of RGB values to represent color. How that color is redisplayed is influenced by the color space because the same RGB values can render very different colors depending on the color space.
Although color space might sound esoteric, the concept is pretty clear when considering something like your logo. Organizations and brands spends enormous marketing budgets to ensure consistency of their corporate identities.
The discussion of color fidelity is moot unless you've calibrated your monitor.
Your color space decision depends on the final output. Generally speaking, for web use sRGB is the most practical and safe color space.
Metadata, the data that describes your content, helps you and others find specific images. The efficiency with which you or others can find an image increases your library's market value and can save your staff time and money.
One best practice is to add IPTC metadata to your files prior to upload. Separate software like Adobe Lightroom, Photo Mechanic, and even the Mac's Photos application can help you and your Contributors if you'd like to add image metadata before uploading to Libris. Libris will pull in and display whatever embedded metadata is on your image at the time of upload.
Uploading Video, Audio, and Other Files
If your subscription offers video support, you can upload image and video files.
- Video can be uploaded via the Library web uploader, Contributor web uploader, FTP, or mobile app.
- The current file size limit for video files is 20 GB.
