Remove guides from the image
❖ Do one of the following:
• To remove a single guide, drag the guide outside the image window.
• To remove all guides, choose View > Clear Guides.
Set guide and grid preferences
1 Do one of the following:
• (Windows) Choose Edit > Preferences > Guides, Grid, & Slices.
• (Mac OS) Choose Photoshop > Preferences > Guides, Grid, & Slices.
2 For Color, choose a color for the guides, the grid, or both. If you choose Custom, click the color box, choose a color,
and click
OK.
3 For Style, choose a display option for guides or the grid, or both.
4 For Gridline Every, enter a value for the grid spacing. For Subdivisions, enter a value by which to subdivide the grid.
If desired, change the units for this option. The Percent option creates a grid that divides the image into even sections.
For example, choosing 25 for the Percent option creates an evenly divided 4-by-4 grid.
5 Click OK.
Use snapping
Snapping helps with precise placement of selection edges, cropping marquees, slices, shapes, and paths. However, if
snapping prevents you from correctly placing elements, you can disable it.
Enable or disable snapping
❖ Choose View > Snap. A check mark indicates that snapping is enabled.
To temporarily disable snapping while using the Move tool, hold down Ctrl.
Specify what to snap to
❖ Choose View > Snap To, and choose one or more options from the submenu:
Guides Snaps to guides.
Grid Snaps to the grid. You cannot select this option when the grid is hidden.
Layer Snaps to the content in the layer.
Slices Snaps to slice boundaries. You cannot select this option when slices are hidden.
Document Bounds Snaps to the edges of the document.
All Selects all Snap To options.
None Deselects all Snap To options.
A check mark indicates that the option is selected and snapping is enabled.
If you want to enable snapping for only one option, make sure the Snap command is disabled, and then choose View >
Snap To and choose an option. This automatically enables snapping for the selected option, and deselects all other
Snap To options.
