Want to be featured on 500px ISO? Every week, we’ll announce a new photo challenge theme. You’ll have until next Monday 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 new photo.

Last Week’s Mobile Photography Contest Winners
They say the best camera is the one that you have with you. For some of you, it’s the phone in your pocket. Last week, we asked you to shoot and submit pictures taken with your mobile device, whether it’s an iPhone, iPad, Lumia, HTC, or Sony Xperia. As a rule, we also asked you to list down the device you used in your photo descriptions. We have received more than 900 awe-inspiring entries. We were stoked to see the various ways you got creative with your technique and choice of subjects, using only a mobile device.

Scroll down to see 33 of the 500px team’s favorite photos from the Mobile Photography contest gallery—from landscape images to still life shots.
