Recently while reading through one of the forums on a popular Microstock site, I came across a cry for help in isolating an image. Another helpful member of the forum replied with his suggestion, and then commented:
but I wouldnt try to isolate something like the hair on a dog. I thought to myself why? Isolating an image can be accomplished in a dozen different ways. The method you choose depends on the image to be isolated.
Lets isolate the fine hairs at the bottom of this dandelion
For this method of isolation Im going to choose the Extract tool under the Filters menu.
As you can see, I have chosen a fairly large brush, and covered both the hairs I wish to isolate, AND a part of the background at the same time
This is my initial and immediate result.
Not too bad, but wait .
And now Im going to take it a step further and really define the hairs on the dandelion.
Go to
Image>Adjustments>Replace color.
What we want is to lighten up some of the darker hairs so as to make them appear finer than they really are.
Using the eyedropper to select a dark area, now adjust the fuzziness to fine tune my selection.
You can see some of the dark areas INSIDE the dandelion have been washed out in the process by moving the lightness slider all the way to the right. In the next step well perform Photoshop Magic to get them back.
Simply choose the History brush to fill back in the areas of the dandelion that were washed out during replace color process. The image has been isolated!
Now bring on that dog you were afraid to isolate!
