One of the great things about getting out and about talking about photo UX is that people share their stories with you.
Scarva are an online supplier of clay and pottery. You can buy it in various quantities from a 12.5kg bag right up to a tonne.
Because it’s hard to imagine what a quantity of something like clay will look like when you receive it they use photography to show you.
This photo above shows you what 25kg of clay looks like so you can clear a suitable space in your studio for it when it arrives.
A nice example of a clever use of photos that improves the user experience, thanks @happygeneralist!
