In this simple montage the glass
vase, the table and the background
are on three separate layers. The task is
to make the background visible through
the vase.
2
Begin by loading up the area
taken up by the vase, by holding
CL and clicking on its thumbnail
in the Layers panel. Then use the
Elliptical Marquee tool, holding down
COLA to limit the area to just
the bowl itself.

Now for the tricky bit – adding
back the reflections from the
original vase. Duplicate the vase layer,
and delete the layer mask (without
applying it). It will completely obscure
the distorted background. Now choose
Layer > Layer Style > Blending Options
and drag the small black triangle under
the This Layer slider (in the Blend If
section) to the right. After a certain
point, the vase will begin to turn
transparent as all pixels darker than the
position specified disappear.

LASS OBJECTS NOT
only reflect what’s
around them, they also refract
the view behind them. This
refraction is easy to achieve;
the trick to making the
montage look real is to bring
back the reflections in the
original photograph so that
they sit on top of the refracted
image.
In this workthrough, we’ll
make this photograph of a
glass vase look as if it’s sitting
within the scene, rather than
simply stuck on top of it.

HOT TIP
Spherizing works
well with spherical
objects, as you’d
expect. But if you
want to distort the
view seen through
a cylinder, such
as a glass wine
bottle, you can still
use the Spherize
filter; this time,
though, change
the mode of the
filter from Normal
to Horizontal Only
in the filter’s dialog
box.

Dragging the slider produces a
hard cut-off as pixels darker than
(in this case) 173 are hidden. That black
slider is actually two sliders pinned
together: to split them, hold down
O A and drag on the right half of
the slider. When this is pulled all the
way over to the right, any pixels whose
brightness values are higher than 243
(in this instance) are fully visible; those
pixels whose brightness values lie
between the two sliders fade gradually
from fully opaque to fully transparent.
Using Blending Options in this way
to hide and show areas of a layer
selectively is an extremely powerful tool:
find out more about how it works in
Chapter 3, Hiding and Showing.
As a final touch, the refracted
background seen through the vase has
been given a blue-green tint using the
Color Balance dialog; I also painted out
some of the stem on the layer mask to
make it partially transparent.
3
Now hide the bowl layer, switch to
the background and make a new
layer from the selection using Cj
Lj.
4
Reselect the new layer by C L
clicking on its thumbnail in the
Layers panel, and use the Spherize filter
to create the refracted view. (If the bowl
had been full of water, you’d need to flip
this vertically to simulate the solid lens
refraction.)
5
Turn on the vase layer so it’s visible
again, and create a layer mask.
Using a large soft-edged brush, paint
out the interior of the bowl so that the
background becomes visible.
