When taking a picture of an
object, the exact background is no longer as important as it once was
because we can now change it so easily in Photoshop. For example, #1 is
a picture I recently took of a vase that I was preparing to offer for
sale on an Internet auction service. But after I took the picture, I decided
that the background did not exactly show the vase off very well.
Make Your Selection
The first step is to make a "selection" of the vase. There are many ways
to make selections in Photoshop. For this particular picture, I chose
to use the Quick Mask Tool. When you invoke Quick Mask you then use the
Paint Brush to apply a red-tinted "mask" to the image that you want to
select. You simply "paint" the color onto the picture. In order to do
a good job, I always magnify the image (Ctrl plus the + key) until I can
just begin to see the actual pixels. Then, I select a soft-edged brush
that will allow me to get close to the edges without spilling over. The
exact size of brush depends on the resolution of the image, the complexity
of the edges that you have to paint around, and the magnification of the
image that you have selected. In this case, I was working with an 8x10
sized image that was set to 300ppi. I used a 50 pixel soft-edged brush.
The start of painting around the edges of the vase using Quick Mask is
shown in #2. You can see the vase after I had painted all around the outside
edges in #3. The task of delicately painting in the outside edge of the
object is time consuming and slow if you do it correctly. If you make
a mistake and paint over the edge, you can erase the mistake with the
Erasure Tool and a similar sized brush. Then, switch back to the Paint
Brush Tool to continue painting using Quick Mask.
Once the outside edge was painted
in, I could switch to a much larger brush (200 pixels) and quickly paint
in the rest of the vase. The vase with the Quick Mask completed is shown
in #4.
Next, turn the Quick Mask mode
off and the image will show up with the normal "dancing ants" all around
the selected object.
Since we painted in the object
that we wanted to select, we now have to reverse the selection in order
to perform the actual selection on the object. So, go to Select to Inverse.
Next, go to Edit to Copy in order to copy the selected vase to the imaginary
storage space in the computer known as the Clipboard.
New Canvas
Next create a new, blank canvas. In this case I created a new, blank canvas
that was 8x10 and had a resolution of 300ppi. Now, go to Edit to Paste
in order to paste the image of the vase onto the new canvas from the Clipboard.
See #5 for the results.
Now it's time to create a nice
background. Highlight the Background layer in the Layers Pallete in order
to make it active. Then, be sure that the colors black and white are set
up as the foreground and background colors. Finally, get the Gradient
Tool and choose the circular option. Place the cursor in the dead center
of the image and with the left mouse key, drag to any outside corner and
release. That will lay in a circular, gradient, white-to-black background.
Then, in order to lighten it up a bit, I went to Image to Adjustments
to Brightness/ Contrast and lightened the entire background layer a little.
See #6 for the results.
At this point, I had a nice
vase, and a nice background. But, the vase seemed to be floating in midair
making it look a little unnatural. It needed a drop shadow! And, here
is what this column is all about-putting in a drop shadow for a three-dimensional
object.
Start by going to the Layers
Pallete and dragging the layer with the vase into the Create A New Layer
icon at the bottom of the Layers Pallete. I call the little icon the Duplicating
Machine! Next, highlight the second layer. See #7.
Now, go to Image to Adjustments
to Hue/Saturation. Drag the Lightness slider bar all the way to the left.
See #8. That will turn the vase in Layer #1 to a solid black color.
Now, go to Edit to Transform
to Distort. See #9.
Grab the little handle that
the red arrow points to in #10 and drag the handle downward. Play with
it. You'll get the idea. In my case, I continued to drag the little handle
down until the image looked like #11. At this point, hit the Enter key
on the keyboard to render the effect. Then get the Move Tool and drag
the shadow around a little to better position it, as in #12.
Now we have the shadow, but
it is way too crisp and a little too dark to look real. So, in order to
soften it up a bit, go to Filter to Blur to Gaussian Blur. The Gaussian
Blur Tool allows you to select the degree of blur that you want. This
is a judgment factor. Just drag the little slider bar and watch the shadow
in the image. When #13 looks right, stop!.
Now in order to lighten the
shadow a bit, go to Image to Adjustments to Brightness/Contrast, and again,
lighten the shadow until it looks right. See #14. Now, the vase no longer
appears to be floating in midair.
By the way, if you are having
trouble getting your printer to produce what you see on the monitor screen,
you need to do a little color calibration on your system. I have a CD-ROM
that walks you through the calibration process. It's easy to do with Photoshop
5.5 or higher and any Epson ink jet printer. I normally sell the CD for
$19.95, but I'll make it available to Shutterbug readers for just $3 to
cover my costs. Send an e-mail to me care of Shutterbug (editorial@shutterbug.net)
and I'll tell you where to send the money.
