Vacation help me out

Going to Yosemite the first week of September. How long will it take to see it and what all do I need to see? Going from there to Tahoe. What do I need to see there? From there going to the Redwoods. Need to know what to see there. Heading down coast to San Francisco. If you have traveled this, how long will it take and what spots should we stop to see. Thanks. Dale Out of Okie land

Dale, it's utterly impossible to make a meaningful reply, since we have no idea how you like to shoot. If you're content to walk a few yards from the popular pull-out areas and snap a few shots, you could 'do' Yosemite in a day. If you're up for some short hikes, and are willing to wait for a particular scene to be lit with the best light, the potential increases vastly and several weeks starts to sound more realistic. There is no 'must see' list and there is no 'right' answer to your question.

FWIW, IMO, Tahoe doesn't offer anything significantly different from Yosemite. If time is short, consider skipping it. Spend the day or two saved in the Yosemite High Country, Mono Lake, and/or Bodie, or ?
