This is a fast way to navigate across the image, especially when zoomed in. It is similar to the existing feature in the Photoshop app itself. Here’s how to use it:
• Press and hold H.
• Click and drag to set the position of the zoom rectangle as desired. The zoom rectangle is shown as an outline around the cursor.
• Release the mouse. The image zooms to the area chosen in the previous step. The selected tool remains unchanged.
• If you start in Fit View mode or smaller, the zoom rectangle will represent 100% pixel view (1:1). This is a quick way to zoom to 1:1 at a specific part of the image (such as a person’s face, or other area of interest).
• If you start zoomed in, then after you release the mouse you’ll return to the same zoom level. For example, if you start at 200%, then after releasing the mouse you’ll be back at 200%.
Note: Birds Eye View is only available when GPU is enabled.
