Creating, opening, and importing images
To create a new image
Use the New command to create a new, blank image. If you’ve copied a selection to the clipboard, the image dimen
sions and resolution are automatically based on that image data.
1
Choose File > New.
2
If desired, type a name for the image, and set the width and height.
(Photoshop) To match the width and height of the new image to that of any open image, choose a file name from the
bottom section of the Windows menu.
3
(Photoshop) Set the resolution and mode.
4
Select an option for the contents of the background layer (Photoshop) or first layer (ImageReady) of the image:
White
Fills the background or first layer with white, the default background color.
Background Color
Fills the background or first layer with the current background color.
Transparent
Makes the first layer transparent, with no color values. The resulting document has a single, trans
parent layer as its contents.
5
Under Advanced, choose a color profile, or choose Don’t Color Manage This Document. For Pixel Aspect Ratio,
choose Square unless you’re using the image for video. In that case, choose another option to use non-square pixels.
6
When you finish, you can save the settings as a preset by clicking Save Preset, or you can click OK to open the new
file.
