| Steps for the Layer Mask Technique 
 | 
        
       
      Step 1: Open both images in PS. Make a duplicate copy of each file then close your 
originals. With both images onscreen at the same time select the darker one and 
press CTRL-A. Then press CTRL-C to copy it. Close or minimize that file as you will 
no longer need it. Select the lighter image and press CTRL-V to paste the darker 
one onto it. Look at the Layers palette (Figure A) and you will see two layers. The 
darker image is Layer 1 and the lighter image as the Background Layer.
      
            
      Step 2: Next click the second icon on the lower left of the Layers palette to add a 
Layer Mask. A white rectangle will appear next to Layer 1. (See Figure B).
      
            
      Step 3: Click on the background layer on the Layers palette and then press CTRL-A. 
Press CTRL-C to copy the whole image. Now hold down the ALT key and click on 
the white rectangle next to the Layer 1 palette. The whole image will turn white. Now 
press CTRL-V.  You will see a black and white (B&W) mask image. (See Figure C).
      
      
      
      Next go to top menu selections and click on Filter / Blur / Gaussian Blur and set 
the Radius to about 40 pixels. (See Figure D)
      
            
      Click on the Background Layer. Now you have a new blended image. At this point you 
can fine-tune the brightness/contrast, colour saturation and any other editing before 
saving the file. Note: the size of the resulting file will be larger than the originals due 
to the saved layers. It's a good idea to save a copy as a TIFF(uncompressed) for later 
editing if needed. For web viewing save as a JPEG.
