Join our Washington Post photographers in capturing the solstice and share your summer photos with us through the popular smartphone application Instagram. All you have to do is include the hashtag #wpsummer in your photo caption to send your photo to us.

Using the hashtag means you have permission to send them to us ( you took them) and you allow us to use the photos on, on our social media accounts, or in print.

Here are some of our favorite photos our readers have submitted:

How do I start using Instagram?

To use Instagram, you must have a smartphone for Android or iOS. Download the app and follow the on-screen instructions to set up an account and start snapping photos.

Reminder: Include #wpsummer in the caption. More questions about the app? Check out the Instagram FAQ.

What if I don’t have a smartphone?

We recommend you check out our summer fun gallery and upload your photos directly there.

Have you done this before?

We started off with #econdebate, our first experiment in using Instagram to visualize what the economy looks like across the country. That project has transformed in the larger 2012 Unfiltered. Seasonally, we have done #leafscape for fall and #springscape for spring.
