We’ve all seen those dramatic before and after photos along with testimonials of how well people are doing with their diets. But is it really true? Buzzfeed shows you the tricks behind the before and after photos.

Video Summary

The lighting of a photograph makes a world of difference in how a person looks. “Before photos” for weight loss are usually done with flat lighting so that muscle tone doesn’t show up and the subject appears less defined. Having them stand in a slouched position adds to the effect. For the “after photos,” the lighting is changed to create more shadows which shows muscles and makes the subject appear more toned. Having subjects stand in a different pose, with their body slightly turned from the camera completes the photo.
