This Hindi spoken tutorial will demonstrate you in Adobe Photoshop to how to select and edit particular area which is in focus in image.

 

 Focus Area Selection in Photoshop-

 The intent of this feature is to allow automated selections of elements within an image that are in focus. This is a unique method of creating a selection because other selection tools rely on contrast, edge detection or color information. This feature searches for pixels that are in focus.

If we have an image where we need to isolate a person or subject from the background, and that person or subject happens to be in focus (inside the depth of field) while the background is blurred and out of focus, Photoshop can now analyze the image, figure out what’s in focus and what’s not, and make a selection of just the area we need.Photoshop lets you easily select the areas/pixels of an image that are in focus.

Do the following:

1.With the image open in Photoshop, choose Select – Focus Area. In the Focus Area dialog box, you can make changes to the default selection.Right away, you’ll see animated dots appearing in the lower left corner of the dialog box, telling us that Photoshop is up to something. What’s it up to? It’s analyzing the image, looking for areas that are in focus:                                                                                                      The animated dots in the bottom left corner of the Focus Area dialog box.

Let Photoshop do its thing until the dots disappear.

Wait until Photoshop is done analyzing the image, at which point the animated dots will vanish and our initial focus-based selection appears

2.Adjust the In-Focus Range parameter to broaden or narrow down the selection. If you move the slider to 0, the entire image gets selected. However, if you move the slider to the extreme right, only the parts of the image in clearest focus remain selected.                                                                                                                                                     There are different types of View mode available, If a white background makes it tough to see your selection, you can switch to a black background by choosing On Black, or choose Overlay to view it with the Quick Mask overlay. The On Layers view mode will show a transparent background, great for when you’re trying to blend your selection with a different image on a layer below it. Or, choose Black & White to view the selection as a layer mask. Notice that each view mode has a keyboard shortcut in parentheses, making it easy to switch between them from the keyboard (press W for On White, B for On Black, etc). If you don’t want to remember all of the shortcuts, just press the letter F repeatedly to cycle through them.

 
  1. Use the brush controls to manually add  or remove  areas from the selection.
       Also notice something very important. I don’t have to paint over the entire missing area, the way I would if I was painting with Photoshop’s standard Brush Tool in Quick Mask mode or on a layer mask, I only need to paint over a small sample of the area I want to add. The reason is because when we paint with either the Focus Area Add or Subtract Tool, Photoshop looks at the area we’ve painted over, then re-analyzes the image and looks for other areas that are the same, or very similar, to that area. It then adds or subtracts those additional areas as well. 
If the area you need to remove is relatively large and there isn’t a lot of detail to it (as if often the case with an out-of-focus background), it often helps to paint with a larger brush. One way to change the brush size is with the slider in the Options Bar. Click on the little arrow to the right of the current Size value to access the slider, then drag it left or right
 

     4.If the selection area has noise, control it by adjusting the Advanced – Image Noise Level slider control.

Note:You can leave the Auto option selected for In-Focus Range and Image Noise Level. Photoshop automatically selects appropriate values for these parameters.


  1. At any point, while making changes to the Focus Area selection, you can toggle the Preview option to see the original image.                                                                                                                              
  2. If necessary, select Soften Edge to feather the edges of the selection.                                                          
  3. If you want to fine-tune the selection edges, click Refine Edge.
  1. Once you’ve adjusted the selection to your satisfaction, determine whether the refined selection should become a selection or mask on the current layer, or produce a new layer or document. You can choose one of the following output options:
  • Selection (default)
  • Layer Mask
  • New Layer
  • New Layer With Layer Mask
  • New Document
  • New Document With Layer Mask

 

  1. Click OK.
