We went through Big Sur a few months ago. There's only one or two especially good photo ops there unless you hike a lot, and then it's one or two more. The 17-mile drive offers many more photo ops (5-10) that I like better. And the coastal cliffs and remote beaches between Santa Cruz and Pescadero are also good for walking and taking good photos. Big Basin Redwoods is very good for photos, especially if you decide to skip Muir Woods (similar photos in both).
Speaking of photos, Lombard Street is a little tricky. The best photo will be taken from about a half block beyond the bottom. The wait for the line of cars at the top can be 5-20 minutes, or you can walk it. Cable car, when you come back towards the piers or GS on the cable car, get on the front of the car (standing-holding on) on the left side (center of the street), for unobstructed photos and videos as you come down the hill towards the bay.
