If you are into a good dayhike, and the weather is right, Mt Talac is a good one with some killer views of Tahoe and the Desolation wilderness. Fallen Leaf lake in the area can also be pretty photogenic at the right time of day...

For general photographic spots, there is always the Emerald Bay area lookouts off 89.. The Volkingsholm one has the best variety from a single spot... Has the nice castle down by the lake, access to Eagle Falls, etc...

I'll see if I can remember any other good ones for ya...
