Chapter 4: Working with files
When working in Adobe®
  Photoshop®
  Elements the format that you save the file in is very important. For example, you 
often might have a file in one format, such as JPEG that you edit and then save to another format, such as PSD (the 
Photoshop
  Elements native file format, which preserves layer information and applies no compression). 
Understanding the differences between formats is therefore an important part of photo editing and sharing. You have 
several choices about working with files. You can set options for opening, saving, and exporting files by type, by file 
size, and resolution. You can also process and save camera raw files. These tools make it easy to combine files of 
different types and optimize them in Photoshop
  Elements. When creating a new document, you also need to decide 
what format, and what resolution, might be required. All this information will be covered in this chapter.
Opening files 
Create a new blank file
To create a web graphic, banner, or company logo and letterhead, or to create a photo collage or scrapbook page by 
mixing parts of different images, start from a new blank file. 
1
From the File menu, choose New
  > Blank File. Or, on the Welcome screen, click Start From Scratch.
2
Enter options for the new image. 
Name 
Names the new image file.
Preset 
Provides options for setting the width, height, and resolution of images that you intend to print or to view 
on-screen. Select Clipboard to use the size and resolution of data that you copied to the clipboard. You can also base a 
new image on the size and resolution of any open image by choosing its name from the bottom of the Preset menu.
Width, Height, and Resolution 
Sets these options individually. The default values are based on the last image you 
created, unless you’ve copied data to the clipboard.
Color Mode 
Sets an image to RGB color, grayscale, or bitmap (1-bit mode). You usually should select RGB.
Background Contents 
Sets the color of the image Background layer. White is the default. Select Background Color to 
use the current background color (shown in the toolbox). Select Transparent to make the default layer transparent, 
with no color values—the new image will have a Layer 1 instead of a Background layer.
Be sure to choose the correct size and resolution before beginning to edit. Changing those settings after editing could 
introduce blurriness or require pixels to be removed. Other settings can be changed after editing.

Import submenu.
