How to Create a New Image in Photoshop CS6
At some point, you want to create a new image from scratch in Photoshop CS6. Follow these steps to use the New feature to create a new image:
Or press Ctrl+N (Command+N on the Mac).
Type a name for the new file.
If you don't specify a name, Photoshop creates one for you.
In the New dialog box, select a preset image category from the Preset pop-up menu.
Choose from common categories such as U.S. Paper, Photo, web, Mobile and Devices, and Film and Video.
In Version CS6, there are now14 (CS5 sported only five) different presets in the Mobile and Devices category to accommodate creating images for the iPhone, iPad, and other mobile devices.
The Clipboard provides the size that corresponds with an image that you copied. Here are a couple of other preset tips:
You can also choose to match the size of any open file. Open files are listed at the bottom of the Preset list.
If you select Custom, Photoshop also allows you to create a user-defined custom preset based on your defined settings: After you define your values, click the Save Preset button in the New Document Preset dialog box. Choose any or all the options you want to include in your preset. When you choose not to include an option, Photoshop displays the last used value for that option. Click OK.
If you selected an image category from the Preset menu in Step 4, select your desired preset Size for that category.
Or, if you chose Custom in Step 4, enter the width and height of your image manually by typing the width and height of your choice in the text boxes.
Note that any Preset sizes automatically revert to Custom when any of the preset's values are changed, and that when you change the units for either width or height, the other dimension also changes. You can hold down the Shift key to change both width and height independently.
Like with other Photoshop dialog boxes, you may change from the default unit of measurement of pixels to another, such as inches.
Enter the resolution for the new document.
When you select a Preset image category and size, the recommended resolution is entered for you. You can change this resolution if desired, but remember that selecting the right resolution at this point in the creation process is important because if you need to change the resolution later, you degrade image quality.
Note that Photoshop gives you the size of your image file, based on your settings, in the lower-right portion of the dialog box. This information is good to know if you're targeting a specific file size for your image.
From the Color Mode drop-down list, select a color mode.
Select your desired color depth for your document.
Only one-bit color depth is available for bitmap images. (Each pixel is either black or white.) The 8-bit and 16-bit color depths are available for the other color modes. And you may also create a new 32-bit image in RGB or Grayscale modes.
In the Background Contents drop-down list, select an option for how you want the background layer to be filled.
Click the Advanced button to display a couple of additional options:
Color Profile: Assigns a color profile (a definition of the way color looks in a document) to your new document. The default, Adobe RGB (1998), is fine when creating a new document unless you have good reason not to. This setting provides a nice, large gamut of RGB colors.
Pixel Aspect Ratio: Selects an aspect ratio (the relationship of width to height of a pixel). The default setting of Square is fine for print or web images. Images for digital video content may require a non-square aspect ratio, such as D1/DV NTSC.
Click OK when you finish entering your options.
