The Blur Gallery in Adobe Photoshop is different from the Blur Filters we've covered previously (both are found in Photoshop's Filter menu). When you select Blur Gallery, Photoshop displays another dropdown menu with five Blur options: Field, Iris, Tilt-Shift, Path, and Spin Blur. These filters are much more interactive than regular Blur Filters, with live previews and on-image controls, including options to create Bokeh effects.
Blur Gallery Tools
To use Blur Gallery features, open a file, then use the Lasso tool or the Magic Wand to select the area you want to smooth or soften. It works best if you cut out the selected area, paste it back in as a new layer, then ensure that this layer is active in the Layers panel. The blur will affect the entire selected area unless you use the Pins to select specific sections.
