I've saved my progress as far as Nicely refined masks.psd and everything looks hunky-dory except we're missing an obvious ingredient in these eyes and that's the pupils. If you take a look at the Final Na'vi here, we've got these big ginormous pupils because they live in this misty gloomy world I guess and their eyes need a lot of light in order to cast an image onto the retina. So, let's switch back to nicely refined masks and as opposed to using the original girl's original pupils which are of no use to us because they were so tiny and they're all squished now anyway.
I just went ahead and drew a couple of black circles and I did that by the way I'll go ahead and turn on that new pupils layer so you can see it. I'll click on the new pupils layer to make it active and all I did, this one's definitely not rocket science, I chose the Elliptical Marquee tool, I went ahead and drew a circle, so I'm pressing the Shift key in order to constrain the shape of that ellipse, I press the dekeKeys, deke is in default to make my foreground color black and then I pressed Alt+Backspace or Option+Delete to fill that selection with black.
End of story, that's all I did, which is why they don't look like much quite frankly. I'll undo the third eye there by pressing Ctrl+Z or Command+Z on a Mac and I'll click off in order to deselect the image. We don't have any integration going on at this point time between the pupils and the eyes. So, I'm going to zoom in so that we can take in the pupils in glorious detail here, and what I'm going to do is take advantage of luminance blending. So, with the new pupils layer selected, I'm going to go up to the Layers panel menu and I'm going to choose Blending Options or you can press Ctrl+Shift+O, if you loaded D keys, Command+Shift+O on the Mac, and that brings up the big old layer Style dialog box.
As we have before I'm going to take advantage of this Underlying layers slider bar and what I want to do is I want to let the highlights underneath the pupils show through. So that means I would drag this white slider triangle over to the left and you can see if I drag it over to something like 185, I'm revealing an awful lot of highlights in this location here covering up an awful lot of pupil. However, I'm also getting some very jagged transitions and this just looks terrible. So, I want to move these halves of the triangle apart from each other, I'll press the Alt key or the Option key on the Mac and drag off the right half of this triangle to the right until I get to 240.
So, what this is saying is from a luminance level of zero which is black up to 185 which is quite light, we are seeing pupil and that's associated with the underlying stuff by the way. So, we're seeing pupil over the darkest stuff in the iris, and then, at 240 and higher, the pupil becomes absolutely transparent and 255 is white by the way, so just this little area is making the pupil transparent. Then over the course of this entire transitional area from 185 to 240, the opacity of the pupils is slowly drifting off.
So, that's all we need to do there, click OK, you can see that it has a great effect on both pupils. This is before and this is after. Now, I think the pupils are too sharp. At this point, they don't look all that integrated into the iris after all, there are to be a little drop-off where the irises are dropping away essentially to reveal the inside of the eye, and we're going to achieve the effect of a soft drop-off using another layer effect and it's going to be a familiar one actually.
I'm going to go ahead and click on the fx icon and choose Outer Glow and that's going to add a glow around the pupil, a kind of corona and that's not what we want at all. So, I'm going to go and change the color once again by clicking on that color swatch, change it to that same color we used earlier, 190, 20 and 40. So 190 for Hue, 20 for Saturation, 40 for Brightness, click OK. I'm going to take the Opacity down a little to 70% and more importantly at this point I don't want the Glow, I want a Shadow.
So, I'm going to change the Blend mode from Screen to Multiply, and we'll get this effect here. Now that's not enough of a glow, so I'm going to raise the Size value to 14 pixels and I'm also going to take up the Spread value which is going to fill up the Size space a little more. Tighten it up so it's not quite so blurry, like so. So just taking it up to 4% does the trick. So 4 and 14 right there Technique leave that set to Softer, we got this dark turquoise Multiply 70% Opacity done, click OK in order to accept that affect and that's not quite enough of a highlight in my opinion off these eyes.
I want a little more of a white burst going on. So, what I'm going to do is I am going to use the Color Range command in order to select these highlights and then I'll fill that area with white and apply a blend mode. So here it goes, first of all, I'm going to switch over to the Rectangular Marquee tool and you can do that by pressing the M key and then I'm going to draw a fairly tight selection around these irises like so, I'm using the Spacebar to align a little bit. I want a little bit of extra edge but not much like that. That will constrain the Color Range command.
So Color Range will automatically select inside of my current selection. I'll go up to the Select menu and choose Color Range or press Ctrl+Shift+Alt+O or Command+Shift+Option+O on the Mac if you loaded D keys, and then, I'm going to switch my Selection Preview to None, so I can see the image itself, I'll click inside of that central highlight and I might Shift+click as well inside of the other highlight area or Shift+drag across it like that, you can raise the Fuzziness value if you want to, I'm just going to take it up to about 60 actually works quite nicely. That's it; click OK in order to accept that selection as you see it there.
Now, I'm going to create a new layer, actually I'm going to tuck up the layer effects on pupils, and with new pupils selected I'm going to press Ctrl+Shift+N or Command+Shift+N on the Mac, in order to create a new layer and I'm going to go ahead and name this one highlights and I'll click OK, and then I'm going to fill this highlights layer, currently, it doesn't have anything on it right now. I'm going to fill it with white. So, I'll press the dekeKeys in order to establish my default foreground and background colors, so the background color's white and I'll press Ctrl+Backspace or Command+Delete on a Mac to fill the selection with white as we see it now.
Now I'll press Ctrl+D, Command+D on the Mac to deselect the image and just for larfs I'm going to change that blend mode to the lightest blend mode there is which is Linear Dodge, which will give us the brightest possible highlights. Now, that's not going to change anything right off the bat with white, but it will ensure that our next step stays nice and bright. I'm going to go up to the Filter menu and choose Blur and then choose Gaussian Blur, or press Shift+F7 if you loaded D keys and I'm going to blur these highlights to the tune of I think about 2 pixels should do it.
That looks pretty darn good actually and at I'll click OK in order accept that modification. And now we have the pupils. This is how the image looked without the pupils, by the way with just these strange glowing irises, and now we have pupils which make these orbs look like a real actual Na'vi eyes, just like in real life.
