thank you for you kind comments, Yosemite is by far one of my favorite places to shoot. -as cliche as it sounds. I honestly think no matter what type of weather, lighting, conditions Yosemite throws at you, that in itself has just the natural beauty.
As far as post process, i don't really have a workflow, i adjust my exposure > color temp > contrast > clarity/sharpness/highlights/shadows, etc.. according to what is pleasing to me. then i add back some grain and i go through LR's B&W presets.
to be honest, i PP'ed #2 first. that was the last landscape shot i got before i left the park and i just loved the fog with the sun breaking through, so the image was still fresh in my head. it was the most difficult shot to get with my limited experience. I had no idea how i was going to shoot it and PP it. I took a couple shots, exposing for canyon wall, grass, fog, etc... then i picked the best one i liked, PP'ed and converted to B&W, and that was the end result. and i feel satisfied with the results.
