Step 4: Making the outer border

Next, we’ll create the white borders that will frame the photos. It’ll be helpful to have the border on a separate layer, so we can move it in front of the pictures. Go to the ‘Layer’ menu, mouse over the top entry ‘New’, and select ‘Layer…’ from the sub menu. You’ll get a window asking you to choose a name for the layer. You can call it “Borders” or something if you want, but it’s not important. Click OK to create the new layer.

Next, go to the tool palette and select the Marquee tool. If you click the button and hold it for a couple of seconds, a small sub-menu will appear with the choices of a rectangular or elliptical marquee. Select rectangular.

Using the mouse, click and hold the left mouse button on the document one grid-square in from the edge in the top left corner, and drag the mouse down to a position one grid-square in from the edge in the bottom right corner, and release. It doesn’t matter if you’re a little off, as the “Snap-to” function will make your selection automatically line up with the grid.

You should now see the “marching ants” marquee indicating the area you’ve selected, which is the area inside the dotted line. However we need to have the area outside the line selected, just the edge of the document. Go to the ‘Select’ menu and click in ‘Inverse’. You’ll see that the selection marquee changes, and that the selected area is now the outer border of the document.

Select the Paint Bucket tool again, and pick white from the colour swatch palette. Click in the selected area of the image and the border should fill up with white, which will be the first part of our border. When you’ve done the fill, press Ctrl-D to cancel the selection.


Step 5: The inner borders

Switching back to the rectangular marquee tool, click and hold on the grid line closest to the centre of the left-hand side of the page, and drag a long, thin box one grid square wide right across the page. Holding down the shift key allows you to add to your existing selection, so hold it down and drag another one-square-wide box from the top to the bottom of the page, making a cross shape.

Again, select the Paint Bucket tool and fill this cross shape with white. After you’ve done this press Ctrl-D to cancel the selection. The border and four rectangular panes are now on a separate layer over a black background.


Step 6: The round window

Click and hold on the marquee selection tool, and select the elliptical marquee.

Click on the centre of the image where the horizontal and vertical frame lines meet, hold down the Alt key, and drag an elliptical line out in a shape like the screenshot below, so it’s about half as wide as the total image. Holding the Alt key makes the point where you first clicked the centre of the ellipse. If you held down the Shift key as well you’d draw a circle. By tapping the arrow keys you can nudge your selection to centre it up precisely.

We’re going to need this selection again, so we’ll save it. Click on the ‘Select’ menu and select ‘Save Selection…’. Choose a name you can easily remember, such as diphenyltrichloroethane or Ellipse_1, and click OK to save it for later use.

Use the Paint Bucket tool again to fill in the ellipse with white. You’ll need to click it four times, since the white bars will block the flow of paint.

Now we need to hollow out the middle of this large white ellipse. Click on the ‘Select’ menu, mouse over ‘Modify’, and select ‘Contract…’ from the sub menu. Set it to 25 pixels, and click OK.

The selection should shrink down by the same width as the border frame lines. Press Ctrl-X on your keyboard and the area inside this modified selection will be cut out, leaving an elliptical white border 25 pixels wide.

At this point we’re finished with the grid, so you can go back into the ‘View’ menu and turn it off.
