If you use the extended version of CS6, there’s a feature lurking deep within Photoshop that you’ve been completely unaware of. Well, it’s an Adjustment Layer so maybe it’s not lurking that deep. The Color Lookup Adjustment Layer lets you pull up different color variations such as Horror Blue, and Candlight. While this isn’t the best tool for doing fine color-tuning, it’s great for creating multiple versions of the same image in seconds.
