APPENDIX C
IMAGE FILE TYPES
There are a range of graphic and image file types that can be used in visual story props. Keep in mind, that higher-quality images result in larger file sizes.
UNCOMPRESSED
high quality, large file size
| EPS Encapsulated Post Script |
Vector-based graphic file, typically created in Adobe Illustrator. |
| TIFF Tagged Image File Format |
Raster-based graphic file with a larger file size and higher resolution. Due to their high quality, TIFFs are frequently used in the print industry. |
| SVG Scalable Vector Graphics |
Vector-based graphic file that is often used in web graphics and animations. |
| RAW sometimes referred to as digital negatives |
An uncompressed image format that is essentially what the camera sees. Those using DSLR or mirrorless cameras often shoot photos in RAW formats due to their high quality and greater post-processing (editing) options. |
COMPRESSED
reduced quality, smaller file size
| JPEG Joint Photographic Experts Group |
A very common, raster-based graphic file that uses a “lossy” compression which can result in a small loss of detail. |
| GIF Graphics Interchange Format |
A raster-based lossless file format that supports both animated and static images, but interprets a small range of colors. |
| PNG Portable Network Graphics |
A raster-based lossless file that is often used for web-formats. It contains an alpha channel allowing for a transparent background in both print or web viewing. |
| PDF Portable Document Format |
A very common method of sharing files since the person receiving the file doesn’t need to have the document’s fonts installed on their computer or mobile device. Depending on where it was created, a PDF can be either vector- or raster-based. A PDF file is viewable on Adobe Acrobat (and compatible programs). The files can include interactive features such as hyperlinks, videos, and buttons. |
| BMP Bitmap image file |
Raster-based uncompressed file. It is an older format, resulting in a larger file size, and is becoming less common. |
