Chuck, Boothbay is also a great place for scenic pictures. I have lived in Central Maine, and Bangor all my life. Email me if you would like some nice day trips. I live about 45 min from Bar Harbor. You have gotten some great recomendations so far, but you need to keep one thing in mind, on the coast, FOG! If you get fogged in head inland in the morning. Louie has given you some good coastal towns also. The trip to Acadia is worth the drive East From Boothbay. 2 hours East. Also when you get on the Island take a left and go down toward Seal cove, SouthWest Harbor area instead of the tourist trap area of Bar Harbor itself. Although the Park loop road is one of the nicest areas in the country. I still go there several times a year since I can remember. There are plenty of senic areas all along the coast. 1) You will need a Delorme atlas. 2) As stated above the coast has alot of coves and sometimes it may take you a couple hours to go a short distance East, but you will find plenty of quaint little old fishing villages along the way! In the front of the atlas there is also a list of scenic areas. Don't be afraid to go inland and spend a day or two in the Nothern Woods area. Millinocket, area along the Penobscot River, or there are a few short 1/2 mile hikes around the Bingham area for Water falls, Moosehead lake region, Carrabasset Valley near Sugerloaf sky area. These are just a few ideas in case the fog is heavey on the coast? You never know; about a 3 or 4 hour drive North from where you are staying. Don't Stop at any Resteraunts Along Route 1, they all rip off the tourist!
You will not be dissipointed. I have lived here all my life of 43 years. My parents took me everywhere as a kid and I am still finding more place to shoot everytime I go out!
Have Fun,
