Your two part project begins with this tutorial called "Extract". The first part of the lesson is to Download the image of the girl with the strawberry. and then complete the tutorial. The second part of the lesson is to find a color photograph of a person with an object. Create a 5x7 inch, RGB, transparent, 72 resolution file and copy the image into that file. (BE SURE TO CTRL-r TO BE SURE THE FILE SIZE IS CORRECT!) Change everything BUT the object into a black and white using the extract method. Save both files, the girl and strawberry and your file. The Extract Method is a sophisticated way to make a selection in Photoshop. It will allow you to separate a part of an image and automatically put the selected work on another layer. Use the tutorial images to learn how to create a selection using the extract method.

Thanks to our friends at Photoshop User for this tutorial.

Duplicate the background layer. We will use this new layer to extract the strawberry from the grasp of our subject.
Go to Filter>Extract.
When the Extract dialog box appears, you may need to increase the size of the image in the viewing window. Select the Magnifying Glass on the left side of the window. Click on the image until it is big enough to view the strawberry's edges clearly. Once you increase the viewing size, you will need to move the image around in the viewer to get a clear shot of all the edges. Do this by selecting the Hand Tool (below the Magnifying Glass) and click/dragging the image into position in the viewer.
Extractions can be tricky, but are fantastic once you get the hang of them. Select the Highlighter Pen tool at the top of the left hand side of the Extraction dialog box. On the right side of the dialog box you will see a section called Tool Options. As the edge of the strawberry is fairly well defined, we need only use a very small brush. I've set my brush size to seven. I've set the Highlight color to green, and the fill color blue. These are just personal preferences. The Highlighter color is the hue that we will draw around the area we want to extract, while the fill color will cover the area to be extracted. We'll see this in action in a couple more steps.
Draw the highlighter around the strawberry and stem. One thing to note about using the highlighter is that you want to stay leave as much of the berry and stem uncovered as possible. Photoshop is going to look for the transition area for the extraction under the highlighter area. As the berry has fairly precise edges, you shouldn't need to adjust the highlighter size. If you were working with hair or something along those lines where the background can bee soon though the strands, then some size adjustments would be required. Work your way around the entire berry.

Select the Fill tool and fill the area enclosed by the highlighter with it.
Time to check out the extraction. Click the Preview button in the upper right corner.
Yikes! That edge looks pretty nasty. No worries though…we can clean that up in short order. Select the Edge Touchup tool from the left side of the viewer.
Run the tool around the perimeter of the berry. This will add and delete information along the edge to better match the area extracted. If a few pixels look as though they do not belong, this tool will remove them. If some pixels were removed that should not have been, this tool will restore them when used correctly. This may take some practice!
Take a look at the top of the strawberry. It appears as though some of the woman's lip remains attached to the extraction. We can take care of this by selecting the Cleanup tool and running it along the top edge, removing the offending pixels.
Once you are happy with the extraction in the viewer, click OK
Take a look at the Layers Palette. Most of the layer has been removed, leaving only the extracted portion.
Select Layer 1 again and make a new copy. Ensure this layer remains below the extraction layer.
Go to Image>Adjustments>Desaturate to remove the color information from this layer.
Click on the Add a mask icon on the bottom of the Layers Palette. Using a mask, we are going to allow color to creep thru the layer from the layer below
Ensure Black is in the foreground. Select a soft, feathered brush. Reduce or increase the size of the brush as needed to fit within the area you want to reveal. Once you have revealed the color on the eyes, you may want to add other areas of color by applying the same technique to the lips, finger nails, and so forth.
Deselect the mask by clicking on the Layer icon in the Layers palette.
Change the foreground color to something slightly brighter (but the same general color) as the eyes.
Your final image should look like this. <
