Similar to a photo filter on instagram, Presets work with Adobe’s Lightroom CC to give you full control of how to edit your photos. One click of a preset gets you the settings you want. They can help your Instagram photos look more professional and consistent. They can also rescue badly lit photos and do some common editing tasks, saving you lots of time!
Unfortunately, with digital goods, it’s not possible. When a refund is requested on the purchase of a physical product, the product is returned and the store owner has some value back. However when a refund is requested for a digital product, there is no way for the customer to truly return the purchased item. It remains in their possession indefinitely.
