To shoot the perfect photo of a white product on a white background all you need to have is a camera and good lighting.
The problem with a white product on a white background is that you risk not seeing all the details of the product. And remember that the physical product must be identical to the product image.
The first important thing to do is to set up your camera, for example, a Canon 5D. You need to set it according to the light source and shooting environment.
You should set your ISO to 100 or 200 and to better capture the photo you should use a tripod. At this point make sure your manual camera setting suits your product. Also, to provide excellent quality with visible details is recommended to shoot at f/16 or f/10.
You can find other different cameras on Amazon, choose one based on your necessities.
You need to find an elevated surface, like a table, where you can place white seamless paper or whiteboard to use as your product background. At this point, you can set your product on it. Then, you need to set your camera at the same level as your product or above, and to do so you could use a tripod. Finally, once your background is ready, you need to start adjusting your light.
To be able to differentiate the white product from the white background, you should shape the light. This is important to also create depth and show all the details, like the shape and texture of the item.
Position your light source slightly behind and above your camera, as seen in the picture above, without lighting the product directly. By doing so you’re going to create shadows and definition of the product, avoiding it to blend into the background and giving it a greyish tone. Once you have your test picture, you can try different positions and angles to see which one suits best your product, find the best lighting until you get the perfect shot.
You can head over to Amazon to find the right lighting kit for your photos.
After you have perfected your lighting and captured the photo, you can go to Lightroom or Photoshoot to fix some details, like imperfections or unwanted reflections.
