Use the Photoshop History Brush every time you want to add effects to an image by using
a brush, especially when targeting very specific areas.
In this exercise we will turn this artists' painting, into a work in progress. (fade)
Open any image of your choice to do this exercise.
Do make sure that your History window is always open and visible.
Select Filter - Sketch- Conté Crayon.
Adjust the preview window by zooming-out.
On the filter selection window adjust your "Relief" slider all the way to the left to
eliminate the canvas texture and keep the other sliders somewhere near the middle range.
Click OK
Now your whole image looks like it has been done with a conte crayon, a conte crayon is
a hi density charcoal used by many artists.
Because we only want the top section of the painting to look like charcoal, we will use
the history brush to achieve this.
It is important that you do this in the following order:
On the History window click on the far left empty square of your last action which reads:
"conté crayon" This sets the source for the History Brush.
Now, click on the action before that, which brings your image back to its normal state.
Select the Polygonal Selection tool.
Click on the left edge of the canvas, now click on the top corner , the right corner,
and a bit down along the right edge.
While clicking and holding your mouse, press and hold the OPTION key, the cursor changes
into the Lasso Tool, move your mouse in an irregular manner across to the left and reach
the end of your lasso.
Now that you have a selection, finally click on the History Brush on the tool box. Right
click and select a soft edge for your brush.
Click and drag your mouse inside your selection, avoiding to go all the way down to the the
bottom edge.
For a more realistic look, choose Image- Adjustments-Levels and move the far right slide handle towards
the middle of the chart. Click OK
Press COMMAND - D to deselect.
And there you are ! , Now it looks like your artist is on his way of completing this painting.
