Here are a few tips for taking the best pictures possible in Cloud City's graveyard:
1. Is the white ghost in your shot? Just wait a couple seconds and he'll fade away, leaving the frame clear for your picture.
2. Feeling lucky? Try to snap a couple pics while the city's controlling your camera movement, you'll get some really uniquely angled shots!
3. Dark is spooky, but is it hard to make out your costume in the pic? If you have Adobe Photoshop, you can use the "Auto-Tone" function under the "Image" menu to bring in a little light without washing out too much of the darkest details.
No matter which location you choose, don't forget to submit your pictures before October 31st, and enter the costume contest on October 29th! Read more about both here.
