Sometimes when I take property pictures for listing there might be unintended objects that I need to blur out. These objects could be people faces, car number plates, business premise name.
For these cases, I will use my trusty Photoshop software's Gaussian Filter tool to blur out the unwanted items.
For today's example the original image has got a middle age woman showing the finger which I want to blur out.
Whip out photoshop, use the selection tool, select the area to blur out, then click filter->blur->gaussian blur
within the Gaussian blur tool you can select how blur you want the picture to be, moving the dail to the right makes the picture more blur.
Finally I managed to blur out the finger.
