Single Use cameras are often referred to as “Disposable” cameras.
They are great for social events like weddings (because nobody can delete the images!) and also art projects.
Warning: there are disposable cameras around loaded with old and out of date film, sometimes even spliced together from smaller pieces. They are often found for sale on Ebay and Amazon. We often process film from these cameras. Our advice is they are a waste of money. They are easy to avoid: they are always unbranded. Avoid un-branded single use cameras. Stick to Kodak, Fujifilm or Ilford/Harman for best quality results.
