To make things easy we have included a photoshop action within the download, the action itself will complete the mirror effect to any of your chosen images.
To load this action into photoshop, from the action panel use the arrow selector shown in red and choose load action - then locate the file mirror effect.atn included within the download - actions folder, if you do this correctly the mirror effect folder will become visible as shown.

Open the master image.psd from the download
to include your image, open any photo into photoshop and choose select all - edit copy merged, this will place your image into the clipboard switch to the master image.psd and choose edit paste then chose edit - transform - scale and resize the image using the drag handles to fit the visible image area, it can be larger but not smaller than the master area dimension, be careful to retain perspective to your image.
when you have completed this press enter and chose select all -edit copy merged, this will place your new image in the clipboard.
switch to the pentax_-enc_hd.psd open the layers panel and make visible the MASTERHOLDER layer, then mouse click on the layer panel to make it active in blue as shown.

You are now ready to apply the action go to the action panel and select mirror effect and then press the play arrow the action will complete - your image insertion is now complete simply position the image to your required location removing from view or delete the image layer being replaced, which are named image 1-4 with reflection respectively.
To finish this process and proceed to the next image you must rename the layer
the new layer is called your image rename as shown below, simply double click on the layer name and insert a unique name for your new layer.

This complete process must be repeated for each of the images you wish to include, when complete save the file which is ready for use in Encore.

This action will compile any clipboard content if you are familar with photoshop as long as the master holder layer is active when applying the action, it will complete without fault.
