Adjust pixel aspect ratio
You can create a custom pixel aspect ratio in existing documents, or delete or reset pixel aspect ratios previously
assigned to a document.
Assign a pixel aspect ratio value to an existing document
❖ With a document open, choose Image > Pixel Aspect Ratio and then choose a pixel aspect ratio that’s compatible
with the video format that you’ll be using your Photoshop file with.
Create a custom pixel aspect ratio
1 With a document open, choose Image > Pixel Aspect Ratio > Custom Pixel Aspect Ratio.
2 In the Save Pixel Aspect Ratio dialog box, enter a value in the Factor text box, name the custom pixel aspect ratio,
and click OK.
The new custom pixel aspect ratio appears in both the Pixel Aspect Ratio menu of the New dialog box and in the
Image > Pixel Aspect Ratio menu.
Delete a pixel aspect ratio
1 With the document open, choose Image > Pixel Aspect Ratio > Delete Pixel Aspect Ratio.
2 In the Delete Pixel Aspect Ratio dialog box, choose the item to delete from the Pixel Aspect Ratio menu, and click
Delete.
Reset the pixel aspect ratios
1 With the document open, choose Image > Pixel Aspect Ratio > Reset Pixel Aspect Ratios.
2 In the dialog box, choose one of the following:
Append Replaces the current pixel aspect ratios with the default values plus any custom pixel aspect ratios. This
option is useful if you deleted a default value and want to restore it to the menu but also want to retain any custom
values.
OK Replaces the current pixel aspect ratios with the default values. Custom pixel aspect ratios are discarded.
Cancel Cancels the command.
Prepare images for use in After Effects
You can import a Photoshop (PSD) file directly into an After Effects project with the option of preserving individual
layers, layer styles, transparent areas and layer masks, and adjustment layers (preserving the individual elements for
animation).
Note: After Effects works in RGB color mode. For best results, work in RGB mode in Photoshop for files you will be
exporting to After Effects. After Effects CS3 can convert files from CMYK to RGB. After Effects 7 and earlier cannot
convert files from CMYK to RGB.
