Amateur's approach to digital landscape photography

I've learned how to access and use the manual focus function of the Sony RX100, though I haven't tried to program the rotating lens ring for that yet.  After observing and conversing with the photographers at Hole in the Wall last week, I present a scheme for shooting that I can use for optimizing focus and exposure in my images using Photoshop.

1. Shoot in raw mode
2. Decide what I want in the frame and where to position it.
3. Colors, texture, patterns, symmetry or asymmetry, shapes, aspect ratio, tall or wide? converging/diverging lines, depth of field (big picture shooting with wide angle) or selective focus (wildflower portrait)
4. Mount camera on tripod
5. Shoot the foreground for focus and exposure in the shadows, ignoring everything else.  To freeze flowers in motion, use a fast shutter speed and wider aperture.  That may require subdividing the foreground into subsections.
6. Shoot the foreground for focus and exposure in sunlit areas
7. Shoot the midground for focus and exposure in the shadows
8. Shoot the midground for focus and exposure in sunlit areas
9. Shoot the background for focus and exposure in the shadows
10. Shoot the background for focus and exposure in sunlit areas
11. With moving water in the frame that covers foreground+midground or midground +background I will focus my little Sony at the boundary hoping for sharpness using a smaller aperture.   
12. To use filters, either handhold them or consider either an add-on magnetic polarizer or adapter rings  to enable use of Lee or other filter systems.
13. At home use Photoshop to view the exposures. select, copy and paste the keeper pixels to one of the exposures, taking care to watch the edges.  
14. I'll probably have to buy a how-to book for Photoshop.

One can't often catch everything in focus and properly exposed in one frame.  Technology allows us to do it well and do it right.  We no longer need to know much about depth of field calculations for different film/CMOS sizes, reciprocity failure, etc.  Just have Photoshop Elements and understand how to use it.
