What’s the best way to achive a pure white background when photographing jewellery. If the product is exposed correctly the background is grey.

Do I need to cut the item out(how do you do this) or is there a quicker way, eyedropper to set the white point is not very successful, also adjusting levels is not perfect.

Depends on how close to white the BG already is. If it’s almost white, then usually a small Curves adjustment will suffice. If you’ve got a long way to go, then drawing a Path around the object is best. Every image will be different.

At the photography stage, you do it by placing the jewellery on glass, above the background and lighting the background separately. That way you can be sure the background burns out whilst allowing you to control the exposure of the subject.

This is a basic photographic technique for shadowless backgrounds.

You need to get a light box. You can also build one yourself, if you want to save money. A lightbox is a simple box that has a white sheet that you place the small object on. The sheet is illuminated with a white light, either from above or underneath.(Usually from above.) You don’t use a flash with it, it’s own light is sufficient for the photo.
B&H Photo sells them, and here is the link to one

There are various types of light boxes, and I think that the easiest one to use is one that has four sides to it, and you place the camera on top of the box, however, any of these boxes will work.
