Trick Photoshop

Focal Black and White effect is one which desaturates a portion of a color photo and retains a portion in color.

It can be done in any version of photoshop.

Step 1 : I have chosen this free stock image. You will find it here

It belongs to Falln-Stock

Step 2 : Click the Elliptical Marquee Tool.

Step 3 : In the Feather in top panel set a high value. I am using a high resolution image. I have set it at 60.

Step 4 : Press SHIFT. Drag out with the Marquee Tool. You will have a perfect circle. Place the circle where you want it, by moving it with the cursor.

Step 5 : Press CTRL+SHIFT+I. The selection is inversed.

Step 6 : Press CTRL+SHIFT+U to desaturate. Press CTRL+D to deselect.

The completed image. Easy was it not.
