Step 2 Add a new layer and fill it with black. Next, go to Filter > Render > Lens Flare and select the 105mm Prime Lens Type with 100% Brightness. Then select Filter > Blur > Gaussian Blur and use 30 pixels for the Radius. The last thing to do with this layer is to change its blending mode to Color Dodge.
Step 3 Add another layer and again, fill it with black. Then go to Filter > Render > Lens Flare and choose the 50-300mm Zoom Lens Type with 100% Brightness. Repeat the same processes for the Gaussian Blur and blending mode as in Step 2.
Step 4 With the Rectangle tool (U), add a white rectangle the width of the page and place it in the centre. Select this layer and go to Layer > Group Layers. The rectangle layer will be inside a folder. Change the blending mode of the folder to Color Dodge.
