Consistency when editing a series of shots

When editing RAWs in Lightroom, I tend to look at each photo in isolation, editing until I'm satisfied with it. When I recently took a trip to Switzerland, I noticed that different photos of the trip had a different kind of feel to them, editing-wise. White-balance was probably the most important source of that, but contrast and saturation were sometimes wildly different as well. I'm not sure if I'm all too happy about that.

When you guys start editing a bunch of shots that belong together, do you try to go for a kind of consistency among them, or do you simply try to make the most out of each individual shot, without taking its siblings into consideration?

I do a bit of both. If I've got a series of shots that are in the same light (bird in a tree, etc) I will set the white balance in the first shot, then sync it to the rest of the series. Pretty much everything else gets done on a shot-by-shot basis.

Generally I do a batch process on everything in a series to get them all looking generically the same. From there, I'll examine each photo on it's own and tweak it to my tastes. This usually keeps a nice uniform base while still allowing each photo to have it's own unique personality.
