Blending Images (examples)

1. Open a background image (either RGB Gray scale). Press the letter "d" to set your foreground color to black.

2. Open a second image. Using the move tool, drag this image on top of the background image in your original document. Make sure this dragged layer covers (or significantly overlaps) the background layer.

3. Go to the layers palette and at the bottom of the palette click on the Layer mask icon. The image doesn't change, but if you look in the layers palette, you'll see another thumbnail icon added to the right of your layer's thumbnail icon. This represents your Layer mask.

4. Click on the gradient tool. Click in the gradient options square and select "Foreground to Background, then take the gradient tool and drag it through the image on the top layer, stopping before you reach the edge of the image. You'll notice that the images now blend together. Use Control + Z to undo if you do not like the blend and try again from another location in the image. You'll need to experiment to see what kind of blend looks best.

5. If you want more control over how your images blend, you can paint directly on the mask by pressing the letter "b" to switch to the Paintbrush tool, choose a large, soft edge brush, and begin painting (you can vary the opacity) in the options bar to have precise control over the image. When you paint with black as your foreground color, the background image paints in. When you paint with white, the top image paints over the back round.

If you don't like the mask you can start over by right clicking in the layer palette on the mask layer and remove the mask

To delete your layer mask, just drag the layer mask thumbnail into the trashcan at the bottom of the layers palette.

You can view the layer mask as a red rbylith, hold Shift - Alt (Mac Shift-Option) and click on the layer mask thumbnail.

You can disable the Layer Mask by holding the Shift key and clicking on it.


This effect works best when added to an existing background image, but it's just as easy to create it starting with a blank background.

1. Open a background image. Create a new layer. Press the letter "d" on your keyboard to set your foreground color to black and background color to white. Fill this new layer with a black to white gradient by dragging the gradient tool from the left edge to the right edge of the image.

2. Go under the Filter menu, under Render, and choose Difference Clouds. (This will render a random texture similar to clouds. Press Control-I (Mac Command-I) to invert the image.

3. Open the Levels dialog box by pressing Command-L and slide the middle triangle (under the histogram) to the far right until the lighting effect appears. Click OK. To bring this lightning effect into your background image you must change the layer mode of the lightning layer. To do this, go to the layer blending modes in the Layer palette and click and select Screen.

4. If you want to colorize your lightning, return the layer mode to normal, press Control-U to open the Hue/Saturation dialog box. Click on the Colorize button in the lower right-hand corner, then slide the saturation slider down to 25. Use the Hue slider to change the color to any hue you'd like, then click OK. You can now change the layer mode from normal to screen to complete the effect.
