PHOTOSHOP: polarizzare foto

Messaggio da admin »

Duplicate the image onto a new layer by clicking the "Background" layer in the Layers palette and dragging it over the "New Layer" button before releasing it. Alternately, use the "Duplicate Layer..." option in the Layers menu to create a duplicate of the background layer.

Select the new layer if it is not automatically selected. Hold "Ctrl" and "Shift," and press "U" on the keyboard to desaturate the layer, removing all color from it; you can also desaturate the layer by selecting the "Adjustments" option in the Image menu and choosing "Desaturate" from the submenu that appears.

Apply a Gaussian Blur filter to the layer by selecting "Blur" and then "Gaussian Blur..." from the Filters menu. Set the pixel radius of the blur to approximately 50, though a value as low as 40 or as high as 70 can produce a good effect as well. Click "OK" to apply the blur

Invert the colors of the blurred layer by holding "Ctrl" and pressing "I," or selecting "Invert" from the Adjustments submenu. This converts the blurred layer to a negative-like image.

Select "Overlay" from the drop-down menu at the top of the Layers palette to change the blending mode of the layer from its normal setting. The original image on the background will be visible again, though the colors may be darker in some areas due to the negative image overlay of the second layer

Right-click the layer and select "Create Clipping Mask" from the context menu that appears if you wish to exclude portions of the image from the polarized effect. Select the "Brush" tool and set the color to white, then adjust the opacity of the tool to 50 percent or lower; the lower the opacity, the less it reduces the polarized effect

Paint over clouds, white objects or other items you want to remove or reduce the polarization of while the clipping mask is in effect. When finished using the Brush tool, right-click the layer again and select "Release Clipping Mask

Flatten the image using the "Flatten Image" option in the Image menu to reduce the image to a single background layer again. Save the image using "Save As..." and enter a different filename from the original picture, so that you will have both an original and a polarized version of the picture.
