During the year the school has proms and other dress up events.
Under the gazebo backlit their features are in shadows, top middle.
Top right fill in flash helps a bit, I thought they might put a qr code there to hint how to get better photos.
I am sure they teach photography , that would be a great chance for a few to come out and help, include families with them
I think if they just stood riight at the front entrance
not under the roof that might work.
In the afternoon the gazeobo side of the pond is bright and sunny but the ooopsite side it is shady. bottom middle. This is the best side to take photos with the fountain in the background, and try using the flash in a couple of the shots.
In the spring the trees are pink. No one working at the park are there at all times, but there are those who plant trees, flowers.. maintaince workers, I bet they would notice and relay the trees are ready for photos.
If bright sun, take photos from the shady side.
Overcast days no squinting or harsh shadows
Observing them, couples, families, or pals,, they come do their thing and are usually gone in 15 minutes.
The shelter house cost nothing to use. It would be a great place for photos and why not plug in music, the school kids and friends/family that came with them could hang out in a social gathering, walk down to the gazebo for pics in a gif
