How to remove the background from our transparent glass that's the topic we are going to talk about
today. So, let's jump into it so here we have a glass with a white background and that's the image
we are going to use as our background so what I’m going to do? I’m going to create a path of this
subject I have already created a mask in order to remove the white background from the surrounding
of the glass. So, I'm going to activate the mask by simply press SHIFT from the keyboard
and click on this mask and you see the background has been removed already. So, I'm going to click
and drag this object into our new background, I'm going to press CTRL+T to reduce the size.
OK so this is our object, now you can see the white background from the glass. Now here we need
to do two things. First, we need to remove the white background and second, we need to preserve
the shadows of the background. So, what I’m going to do first? now I’m going to change the blending
mode from normal to Multiply, once you do that you can see all the whiteness from the glass has been
disappeared. Now only you can see the shadows of the glass, all the brightness has been removed,
this is what happened when you select the multiply mode. When you select this multiply mode all the
whiteness from your layer disappeared, so only shadows or dark pixel remains
and all the white get removed from the layer. So, here you can see the white background from the
glass has been disappeared, that's what we want, but the shadows are very dull so what i'm going
to do? I'm going to press CTRL+J to make another copy of the object, now you can see the shadows
are fine there. Now I'm going to get another copy to get my highlights back. Now you can see the
glass is very dull you can't see any highlights there or shine. I'm going to create another
layer by pressing CTRL+J and now I have the third layer I'm going to change the blending mode from
Multiply to Screen. So, what we got here now? we go this layer for the shine and these two layers
for the shadows. Let me rename them, so you know what we're talking about. So, I'm going to click
I'm going to rename this layer as a shine and I'm going to select these two layers and press CTRL+G
and I name it shadows double click on this layer to get the layer style options and here I'm going
to use this “blend If” options and in “blend if” options, I'm going to focus on this layer.
So, basically what I want to do here? I want to remove all the shadows and the whiteness from the
from the glass but I want to preserve the shine in the glass, So, I'm going to remove all the shadows
by moving this slider on the right. Now you can see all the shadows are start disappearing from
the screen, you see! but you can see all those highlights are still there. So, I'm going to
move this slider all the way on the right until I start seeing …. that's it. Now you can see
the background has been removed from the glass but those harsh edges there, So, what I'm going to do?
I'm going to press ALT from the keyboard or option for the mac users, and I click on this grey icon
and I'm going to break that apart. So, what I'm going to do? I'm going to move this slider all
the way to right to get that whiteness slightly and nicely…. blended with image. So, if I move it
this side on the side you can see all the highlights are coming back
but the highlights are very nicely blended with the image. So, I will move it the way I want … for
example like that! That is fine so now I'm happy with the image and I press OK. So, you see simple
two options one for the Multiply to remove all the whiteness from the image and the second is Screen
mode to remove all the shadows from the image and then we use the “blend if” option to remove
all the shadows and highlights and preserve our shining from this layer and remove everything
else. Now you can see the image is very nicely blended with the background and everything is
there. Now we are going to add shadows into the glass but before that if your glass layer is
not blending nicely with your background here is a quick tip for you. So, simply create another layer
solid color adjustment layer and pick any color from for example this one and press ok.
Now I want to apply this color only into the glass only, so what I'm going to do? I'm going to press
ALT from the keyboard and you see this mask here from the shine, I'm going to press ALT
from the keyboard and option for the mac user and I click on this mask and click and drag
and put mask on top of the new adjustment layer, we created and replace mask? Yes,
press ok. Now you can see all the color we just created is only affecting the gloss layer. So
here you can double click on this and pick any color from here, what you think is nicely
blending with the glass, press okay. Now go to the blending options and select “color” blending mode.
and that's it. Now, simply reduce the opacity!
that's it you can change the color according to your background and for me this will do the job
and now I’m going to add shadow to the glass. So what I'm going to do? I'm going to create
another layer and press “B” from the keyboard to get the brush and hardness all the way ZERO and
size should be big enough to cover the bottom of the glass. I think that will do the job!
Let's change the color from… black and click once, because the shadow there. So now slightly
move the shadow underneath the gloss all the way down just above the background layer, underneath
the glass. Now press CTRL+T to transform and adjust the shadow accordingly, just underneath
and change the blending mode to
Multiply. Always, most of the time we use multiply to blend the shadows with
the background nicely and once you are happy with the background, simply reduce the opacity.
Press CTRL+0, okay. Now that is fine, now you can see our gloss has been nicely blended
with the background and all the unnecessary whiteness from the glass has been removed.
Now there are two things here, first the shine on the glass is too sharp! so what I’m going to do?
I’m going to select the shine layer and reduce the opacity slightly. Now that should be fine,
okay, 75 will do the job and lastly there's another thing we need to pay attention to,
if you pay attention on the background, we have little noise on the background but
the glass is very transparent, very sharp. So what I’m going to do? I'm going to add a little
noise on to that glass. I'm going to create another layer by pressing CTRL+SHIFT+N and
to create a new layer and I'm going to change the blending mode from
overlay and fill with the neutral 50 grey. Okay. so now you can see nothing has happened on the
screen! so basically what happened? I have created a new layer and I’ve filled up with the 50%
grey and if you change the blending option from Overlay to Normal, you can see the grey there,
but I don't want to see the grey here, so what I'm going to do? I'm going to change the blending from
Normal to Overlay. Basically I don't want to see any color on the screen I just want to add the
noise but in order to add the noise, I need to get a new layer and fill up with the any color. So,
I could add the noise. Go to the Filter and Noise and, Add noise and here let me zoom in…
make sure this option is checked
now you can see our glass has been nicely blended with the background if you want to preserve
the noise just to the glass only? you can again copy the mask from the underneath layer press ALT
and click and drop the mask on the noise layer. So before and after…. now you get the idea how to
remove the background from the glass. Having said that it really depends what kind of background
you have behind your glass mirror? If it's a white background it would be a lot easier for
you to remove the background the way I just mentioned and if you have a different color
in the background it would be slightly harder to remove the background but there are other ways
you can do that too. So, I hope this tutorial will help you up and if you have any questions feel
