Mannequins are used instead of human figures to create a 3D effect of various garments such as shirts, pants, jacket, cardigan, swimwear, lingerie, etc. But, in the end result, you need to remove the background along with the mannequin and give it a hollow or ghostly look. This is why it is called the Phantom Mannequin Effect, which is also known as the Invisible Mannequin Effect. You can create the same effect by using transparent mannequins or removable ghost mannequins. But, after taking the photo, you may need photo editing services to create the effect perfectly. So, to save time and money, many photographers avoid expensive transparent mannequins or removable phantom mannequins. Because photo editing is more profitable.
Using a model for product photoshoot can give your product the 3D or 360-degree viewing experience and solve the problem, but with a model photoshoot. So, to get the 3D look of your e-commerce product, you can use the ghost mannequin effect.
You can also call it a neck-joint effect. In the phantom mannequin effect, a photographer shoots product with a mannequin and then removes it in post-processing of the image via photo editing software such as adobe photoshop.
