Want to be featured on 500px ISO? Every week, we’ll announce a new theme. You’ll have until next Sunday to submit your photo as an entry. You may already have an existing photo that fits the theme, or you can take this as a challenge to shoot and upload a brand new photo.

Last week, we asked you to submit photos that fit the theme, Reflection. We’ve gotten more than 600 entries! Thanks to everyone who submitted their creative reflective images! Below are our 30 favorite Reflection photo submissions which captured reflective surfaces, from water to windows.

Browse more shots from last week’s Reflection photo challenge.

Next week’s theme: Close-up

1. Select a photo that fits this theme. Upload the image to your 500px profile, or pick an existing photo.
2. Add the tag 500pxCloseup.
3. You’re done! To track all entries, click here.

From portraits to macro, the theme is open to your own interpretation. So grab your gear, start shooting, and tagging now! Deadline is June 29th at 11:59PM Pacific Time.

As always, we held a random draw giveaway for all those who enter the challenge. Anyone who enters the contest will have the chance to win two months of Awesome membership. This week’s lucky winner is Nikita Maydanov ! Congrats, Nikita, we’ll be contacting you and upgrading your account to Awesome shortly.

We can’t wait to see your close-up photos! Good luck, everyone!
