I'm watching those very grainy 1st season shows now. It reminds me of a raw '70's movie feel. Very non-tech. Funny how movies in the 1950's looked clearer and sharper and the color was so much better then than it was 20 years later in the '70's. But the grainyness doesn't bother me.
What always has struck me though is the overly false bright and cheery extreme green that all the fields and grass have in the latter years of the show. I think this was due to a post-production electronically colored picture by the "colorists" making the grass look greener than it ever could look in real life. This false looking overly saturated greeny green grass bothers me more than the grainy gritty look of the early series, then the grass was sometimes light green or even yellow or brown in places. A much more realistic look than the seemingly painted bright green of the later shows. Anyone else notice how the show got prettier in it's later years?
Yes, I have. I assumed the countyside looked brighter and prettier simply because they then only filmed in the summer. But again, it may be another new filming technique.
