Adding a border. Open your image. Set the foreground/background colours to the

colours you want the border. Select Image > Canvas Size. In the pop-up selection box, ensure that the

Relative box is checked. In the new size boxes, select the width of the

border you want (make sure the two right boxes are set to Pixels.

Select the colour for your border Select OK to apply border.

Making Orton images in Photoshop:

Open any image you wish to try the technique on. Make a duplicate of the image (Image>Duplicate). Close the original image.

Lighten the image as follows: Image>Apply Image… then in the dialog box that comes up change the blending mode to “Screen” and the Opacity to 100%. This will give you an appropriately overexposed image.



Duplicate this overexposed image (Image>Duplicate).

Blur this second image (Filter>Blur>Gaussian Blur… and in the dialog box use a Radius setting of 15 to 50 pixels – the higher the pixel setting the blurrier the photo Experiment with different settings, a radius of about 25 pixels is a good start point.



Now select the move tool from the Photoshop tool bar (or just press “v” on your keyboard for quicker access to the move tool). Hold down the “shift” key and use your mouse to drag and drop the blurry image onto the sharp one (don’t let go of the shift key until after you release the mouse button or the images won’t be in perfect alignment).



Bring up the layers palette in Photoshop (F7 is the keyboard shortcut). Under the word “Layers” in the layers palette will be a menu box of blending modes. Change the blending mode from “normal” to “multiply”.

Now “flatten’ the two layers by pressing “CTRL+E” or by clicking on the sideways triangle in the layers palette to select ‘flatten image’.



If you’re happy with the result, save your file.
