All of the images below were taken mid-day. I took them mid-day because that is the time I was there!
I love blue sky and puffy clouds and the sky is often its blueist mid-day and when the sun is at your back. But you need to watch your exposure. The white clouds are easy to overexpose, and they will look like featureless white blobs.
A strategy for dealing with this is to use a bit of "exposure compensation" (perhaps minus 2/3rd of one stop) to retain the detail in the clouds. Even the simplist cameras will often have this feature, often referred to as EV compensation. Usually you will have a button or a menu item that is written as "+/-". Adding "+" numbers will result in a brighter exposure. Adding "-" numbers will reduce the light and make the overall picture darker or less exposed.
By adding -2/3 EV compensation the clouds will look better, but the shadows in the foreground will get darker. This is not necessarily a bad thing. But if you want to fix it, a bit of "fill light" in processing software like Adobe Lightroom can often help.
I'm not sure I was entirely sucessful in these shots, but I don't think the clouds are noticeably "blown out".
The next three images were taken at Colonial Pemaquid State Historical Site, and the site of Fort William Henry that was originally built in 1692

Birch Point Beach State Park. Beaches up there are never crowded... it seems; though this was taken on Thursday, June 30th, just before the long 4th of July weekend.
