There are 3 methods of compression.
- LZW — this is called lossless compression which means that the data is not deleted to make your image smaller. This is especially good for compressing images with large areas of a single color.
- Zip — Zip is also a lossless method and is popular in the Windows arena. I don’t know many people who haven’t heard of a Zip file, but that is just me! It works well with images that have large areas of a single color.
- JPEG — This is lossy compression. When compressing, JPEG deletes data to reduce the file size. This is a cumulative compression scheme which means that it recompresses every time it saves. Over time, this can degrade the image quality.
Save Image Pyramid
EPS supports Lab Color, Duotones, CMYK, RGB, Indexed Color, Grayscale, DCS, and Bitmap modes.
This format will import and export files in an uncompressed binary format. This doesn’t specify image size, color mode or bit depth. It is simply comprised of bytes that represent the color information in the image. Each pixel is represented by a brightness value, with 0 being black and 255 being white.
Only Camera Raw images contain the actual, unadulterated data captured by the digital camera’s sensor without any camera adjustments, filters, and other processing. This file format prevents any loss of any image data that can sometimes occur when a file is converted from its native format to a more commonly used format such as TIFF or PSD.
