Hi. This is Marty from Blue Lightning TV. If you look at this image, you'll probably
notice that it seems to be slowly moving, however, it's actually a mind-bending, optical
illusion and I'm going to show you how to create it. This tutorial utilizes some features
included in version CC. If you’re thinking of upgrading, I can offer you the newest version
of Photoshop at a 20% discount for only $7.99 per month. It even includes Lightroom, 20
GB of cloud storage and a whole lot more! Click the link in my video's description to
get the discount. The first step is to create a new document. Press Ctrl + N on Windows
or Cmd + N on a Mac or you can go to File and "New". Make the Width: 870 pixels, the
Height: 800 pixels and the Resolution: 150 pixels per inch. The Color Mode is RGB and
8 bits per channel. If you're working on version CC, open the Background Contents list and
click "Other". If you're working on a version earlier then CC, I'll show you what to do
in minute. In the hexadecimal field, type in CED21D. Then, press Enter or Return twice
to close both windows. If you're working on an earlier version of Photoshop, click the
foreground color to open the color picker and type in the same hexadecimal code.
Go to View and make sure Rulers and Snap are checked. If they aren't just click on them.
Go to the ruler at the top and drag out a guide line to the center. It'll snap in place
because we have Snap checked. If you don't see the guideline, press Ctrl or Cmd + H.
Go to the ruler at the left and drag out another guideline to the center. Click the new layer
icon to make a new layer. Open your Rectangular Marquee Tool and go to the center of the guidelines.
Press and hold Alt or Option + Shift as you drag out a circle approximately this size.
Click the foreground color and for the color, type in: 3361FC. Then, click OK or press Enter
or Return.To fill the selection with the new foreground color, press Alt or Option + Delete.
To deselect it, press Ctrl or Cmd + D. Next, we'll squeeze in both shapes. Click on the
lock icon to unlock the background. This releases the background layer, so it can be edited.
Shift-click on the top layer to make it active, as well.
Open your Transform Tool by pressing Ctrl or Cmd + T.
In the Width field, type in 60.
To accept the transform, press Enter or Return twice.
To trim off the transparent sides, go to Image and Trim.
In this case, you can trim it based on any of the choices and click OK.
Double-click the top layer to open its Layer Style window.
Click "Stroke" and the color box. Pick black and click OK.
Make the Size: 50 pixels and the Position is "Inside". Then, click OK.
Make a copy of the active layer by pressing Ctrl or Cmd + J. Double-click "Stroke" to open it in the
Layer Style window. Click the color box and pick white. Then, click OK on both windows.
Next, we'll make the stroke on the right half, black. First, we need to fuse the strokes
into their respective layers. To do this, click the New Layer icon to make a new layer.
Shift-click on the thumbnail of the top shape to make it active, as well, and merge the 2 active
layers by pressing Ctrl or Cmd + E. Repeat the same steps for the shape below it by making
that layer active and make a new layer above it. Make the bottom shape layer active, as
well...then merge the 2 layers. Make the top layer active and open your Rectangular Marquee
Tool. Go to the top, left corner and drag a selection to the the bottom, middle. It'll
snap in place because we have "Snap" checked. Click the Layer Mask icon to make a layer
mask of the selection next to the active layer. Let's hide the guidelines by pressing Ctrl
or Cmd + H. This is the basic image that will ultimately comprise our entire optical illusion.
First, click the thumbnail of the top shape to make it active. Go to Edit and "Define Pattern".
Type in "Optical Illusion" and click OK or press Enter or Return. Go to File and
New. Make the Width: 1550 pixels...the Height: 870 pixels...and the Resolution: 150 pixels
per inch. If you're using version CC, the Background should still be the color you typed
in the first time. Click OK. If you're using a version earlier than CC, click the foreground
color as you did earlier and when the Color Picker opens, type in CED21D. Then, click
OK and press Alt or Option +Delete.
Click the Adjustment layer icon and click, "Pattern".
For the Scale percentage, type in 15 and click OK.
Make a composite snapshot of your visible image by pressing Ctrl + Shift
+ Alt + E on Windows or Cmd + Shift + Option + E on a Mac.
Go to Select and Color Range.
Make sure "Sampled Colors" is selected and make the "Fuzziness", anywhere between 100
and 200. Click on the background to pick up its color. Then, click OK. We now have a selection
around each elliptical shape, however, we need to invert the selection to ultimately
cut the shapes out. To do this, press Ctrl or Cmd + Shift + I. Press Ctrl or Cmd + J
to cut the shapes from the background and copy them to its own layer. Now that we have
all the shapes by themselves, we can hide the composite snapshot and the Pattern adjustment
layer. With your Rectangular Marquee Tool still active, place your cursor in-between
2 shapes at the top of your document and drag a selection over 8 columns and 7 rows.
Press Ctrl or Cmd + J to cut and copy this block of the shapes onto its own layer. Then, hide
the layer under it. Next, we'll center the block of shapes over your document. Open your
Move Tool and press Ctrl or Cmd + A to select it all. Click the "Align Horizontal Centers" icon
and the "Align Vertical Centers" icon. Then, to deselect it, press Ctrl or Cmd +
D. Open your Transform Tool by pressing Ctrl or Cmd + T. Click the Warp icon.
Click the "Custom" tab and click "Fisheye". Then, click the checkmark at the top or press Enter or
Return, twice. Next, we'll create guidelines that will divide our document into 3 equal
sections. Go to View and if you're working on version CC, click "New Guide Layout". If
you're working on an earlier version of Photoshop, I'll show you what to do in a moment. Make
the number of Columns: 3 and the number of Rows: 0. Then, click OK. For earlier versions,
click "New Guide" and tick "Vertical". For the "Position", type in 33.3% and press Enter or Return.
Click back on View and "New Guide". This time, for the Position, type in 66.6%
and press Enter or Return. Open back your Transform Tool, go to the middle anchor point
on one of the sides and when you see a horizontal, double-arrow, press and hold Alt or Option
+ Shift as you drag the transform in until it snaps to the guidelines. Then, press Enter or Return.
Press Ctrl or Cmd + J to make a copy of the layer. Open back your Transform
Tool, go the middle, right anchor point and drag it to the left edge of your document
until it snaps in place. Then, press Enter or Return. Make a copy of this layer and press
and hold Shift as you drag it to the right until it snaps to the right edge of your document.
To hide the guidelines, press Ctrl or Cmd + H.
