To load your stack of images into Photoshop, first launch the app and then go to
> File > Scripts > Load Files into Stack….
At the window prompt, click Browse and select the images you want, they'll be imported after pressing OK
Then once the images are in Photoshop select all image layers (i.e. highlight them in the layers pallet on the right) and go to
> Edit > Auto-Align Layers > OK.
Once the pics are aligned, then the second step is
> Edit > Auto-Blend Layers > Stack Images > OK.
Then SAVE the stacked image to a TIFF or PSD file. At this stage, I will then crop away any unwanted peripheral misalignment
around the edge-border, and also complete any final additional editing that may be required...such as image clean-up, area
lightening, mid range dynamics adjustment, selective sharpening, etc. etc.
