Dude you've got some serious magazine-worthy shots there. Take it from a 30 year graphic arts and photography veteran.
Really fine photos there. Color is gorgeous. May I ask what kind of camera/basic specs?
It's easy to take nice photos when the scenery is nice :-) Seriously, I just go "ohhh, that's purty!", slam on the brakes, yank the camera out of the tank bag, and snap a quick photo in Auto mode with my Canon P&S. It's a much abused A570IS. Nothing special. Not even a polarizing filter.
That said, I do pay attention to light, color, and texture when riding solo and am always on the lookout for nice photo ops. I probably get one RR worthy photo out of every four I take. That's why I hardly take any photos on group rides: no one could stand riding with me given the number of stops I make and the "slam on brakes for a photo" thing.
All those shots were cleaned up in Photoshop using the wizards to tweak levels, color, and sharpness. I manually played around with shadow/highlights and vibrancy (maybe too much saturation on some shots).
If anyone would like a full size version to use on their desktop, just send me a PM with your email address.
