Snowed In: Indoor Photography Contest Winners
For some of us in the northern hemisphere right now, the temperatures have dipped, it’s freezing, the snow’s been falling, and the days are short. Winter has arrived! Last week, we asked you to bundle up and take your photography indoors by capturing scenes of being snowed in.

We’ve received more than 600 indoor photo submissions that portrayed being snowed in this winter. Thank you to everyone who entered and submitted their photos. To view all the images, you can visit our contest gallery.

Want some indoor photography inspiration? From snowflakes on windows to toasty drinks by the fire, below are the 15 winning photos that the 500px team thought were really cool—and made us want to stay indoors all day. Is your photo in here? Scroll down!
