I’d never heard of this lake before, or the open space preserve it was located in. I was just out exploring along Skyline (35,) in the Palo Alto area. It was very peaceful (only saw one other person,) had a good variety of flowers in bloom, and was full of trees. One of the trails even went right alongside a christmas tree farm.
This was shot with the default camera app. Edited with Litely, which is an app I just grabbed last night. I like the subtle effects it adds. I also used Romantic Photo, and ImageBlender to reduce to the opacity of the effect of Romantic Photo.
Here is a shot of one of the flowers I saw out there too.
Snapseed and Mextures for the edit of this one.
