I challenge @biti to take the "newly added rule" B&W Challenge
Pick your own theme but stick to it for 7 B&W shots.

The Rules are:
•Seven black and white images that represent an aspect of your life
• Present one image every day for seven days
• No people
• No explanation
• Nominate someone every day, but anyone can join the fun
• Use the tag - #sevendaybnwchallenge - as one of your five tags
• ADDED RULE: Pick the same theme for all seven days
