Photoshop Tutorial: How to Create a Photo Mosaic from ONE Photo!

September 10, 2019 0 By Peter Engel


Hi. This is Marty from Blue Lightning TV.
I’m going to show you a way to create a photo montage from one large image. The techniques that
I’ll show you are relatively quick and easy and can
be applied to any photo. Open a photo you’d like to use. I downloaded this one and the others
from Shutterstock.com. Click the New Layer icon to make a new layer. in this layer, we’ll create the shape that
we’ll use for our small, individual photos. Open your Rectangular Marquee Tool and drag out a selection whose shape and size approximates the shape and size that you want for your individual photos. We’ll fill the selection with black. To do this. Go to Edit and Fill. Click “Black” and click OK. We’re going to save this shape as a custom brush. To do this, go to Edit and “Define Brush Preset”. We’ll keep its default name. Notice the
thumbnail automatically tells you it’s pixel size. Click OK to save it Press Ctrl or Cmd +D to deselect it. Now that we saved the shape as a custom
brush, we can trash the shape layer. Make a copy of your photo by pressing Ctrl or Cmd +J. Click the thumbnail of the background to make the layer active. We” fill it with white. If your foreground and background colors
aren’t black and white respectively, press “D” on your keyboard. Since white
is the background color, press Ctrl or Cmd +Delete to fill the active layer with white. Click the new layer icon to make a new layer. We’ll be filling this layer with the shape that we saved as a custom brush. Make your photo active. We’re going to
make it into a clipping mask, so the photo will show through the
shapes that will be making in the layer below it. To make your photo into a clipping mask, press Ctrl +Alt +G on Windows or Cmd +Option +G on a Mac. At this point, your canvas should be totally white. Make the empty layer active. Open your Brush Tool and open the Brush Picker. Notice the last thumbnail preset should
be the shape that you saved as a brush. Press Enter or Return and press the F5 key at the top of your keyboard to open your Brush panel. In the Brush Tip Shape window, the
“Spacing” controls the amount of shapes that will appear as you brush across your document. The lower the percentage, the more shapes will be brushed in and the
higher the percentage, the less shapes will be brushed in. For
this example, I’ll type in a 110. Depending on the size
and resolution of your document you may find a different amount works
better for you. Click, “Shape Dynamics”. The “Angle Jitter” determines the variance of angles for each shape, so for example at 0%, all the shapes will have no angles to
them, but at 31%, you can see the difference. Let’s set it at 1% to give each shape a slight variance. Then, click the double-arrowhead icon to
close the panel. Zoom out of your document by pressing Ctrl or Cmd and the minus key on your keyboard a couple of times. Place your brush outside your document.
If you want to make the brush shape larger or smaller, press the right or
left bracket key on your keyboard. Then, brush across your document to reveal your photo. To fit your document back on your canvas, press Ctrl or Cmd +0. Double click on the thumbnail of your
shapes to open its Layer Style window. Keep in mind, depending on the size and
resolution of your document, you may want to use different amounts than the ones I’ll be typing in for this example. Click “Stroke”. I’ll make the size 10 pixels. Make the Position: Inside. and click the color box. Pick white and click OK. Click “DropShadow” no and make its Opacity: 20%. Uncheck “Global Light” and make the Angle 140 degrees. I’ll make the Distance: 10 pixels and the Size: 8 pixels. Then, click OK. Notice the photos that are extending past the document have unwanted borders along the edges To get rid of these borders, zoom out of your document and press Ctrl orCmd +T to open your Transform Tool. Go to a corner and when you see a diagonal, double-arrow, press and hold, Alt or Option +Shift as you drag the Transform out until the borders are gone. If you want, you can also enlarge the photos inside
their respective shapes. To do this, make your photo active, open your Transform Tool and enlarge it. Then, fit it back on your screen. This is Marty from Blue Lightning TV. Thanks for watching!
