As you have become more familiar with Adobe Photoshop, have you noticed that the program allows you to save your images in several different formats or types of files?
It is essential to have a working knowledge and understanding of all of these different formats. This will help you to make the most of your digital photo projects.
While Photoshop has many different types of image file, I've listed and described the three most commonly used.
PSD: This is the most important file format for digital photo editing. A PSD file is a Photoshop file format. There are two main reasons for using PSD when working on your digital photos. To begin with, PSD files allow you to work in layers and channels. This saves your work without compressing the layers. This does result in a large file size. Second, PSD files do not lose their image quality as you work on them. Since there is no compression when the file is saved, there is no lost data. Save your work as a PSD file until you are finished editing your image. Then you can save it in a more appropriate file for each particular project.
A well-known and commonly used file is JPEG. This stands for Joint Photographic Experts Group. As with many formats, files saved in JPEG are compressed, allowing for a smaller file. As with any compressed file, some data will be lost each time the file is opened, edited, and saved. JPEG files have the advantage of working quite well on the Internet and they come with a variety of applications.
A popular file used for applications on the Web and Internet is the GIF file, or Graphic Interchange Format. GIF files are typically small in size so that they can load more quickly in Internet browsers. The number of colors in a GIF File is limited to 256.
Photoshop offers other file formats; however, they are not used very much because they are not Internet use friendly.
For your use, it will be best to save your projects in a PSD file until you are finished editing them. Then, save them in a JPEG or GIF file to save space.
