- It provides learners with meaningful and engaging activities for independent learning.
Choosing a File Format in Adobe Photoshop
- Graphics file formats differ in the way they represent image data (as pixels or vectors) and support different compression techniques and Photoshop features.
- To preserve all Photoshop features, save a copy of the image in Photoshop format (PSD).
- PSD supports files up to 2 GB in size.
- For files larger than 2 GB, save in Large Document Format (PSB), Photoshop Raw (flattened image only), TIFF (up to 4 GB), or DICOM format.
File Formats for 16-bit and 32-bit Images
- Use the following formats for 16-bit images: Photoshop, Large Document Format (PSB), Cineon, DICOM, IFF, JPEG, JPEG 2000, Photoshop PDF, Photoshop Raw, PNG, Portable Bit Map, and TIFF.
- Note that the Save For Web & Devices command automatically converts 16-bit images to 8-bit.
- Use the following formats for 32-bit images: Photoshop, Large Document Format (PSB), OpenEXR, Portable Bitmap, Radiance, and TIFF.
File Compression Techniques
- Lossless techniques compress the file without removing image detail or color information.
- Lossy techniques remove detail.
- Commonly used compression techniques include:
- RLE (Run Length Encoding) - lossless compression; supported by some common Windows file formats.
- LZW (Lemple-Zif-Welch) - lossless compression; supported by TIFF, PDF, GIF, and PostScript language file formats.
- JPEG (Joint Photographic Experts Group) - lossy compression; supported by JPEG, TIFF, PDF, and PostScript language file formats.
- CCITT - a family of lossless compression techniques for black-and-white images; supported by the PDF and PostScript language file formats.
- ZIP - lossless compression; supported by PDF and TIFF file formats.
Importance of Saving Work in Adobe Photoshop
