CEWE Photoworld is part of Europe’s largest photo company, CEWE Ltd, which has been in operation for over 50 years. Their main business is personalised photo products which includes photo books.
Customers like them and they have received 5 stars on the review site TrustPilot, based on over 8,000 reviews, so are probably worth considering if you need to produce a collection of images for a one-off catalogue or portfolio book.
They offer a 100% money back guarantee and have a set of apps so you can make books (and other products) on the go. Quite why you would want to do that we are not sure, but it does give you the flexibility to work on a tablet and other mobile device when the mood takes you. Probably great for dashing off a quick birthday photo mug but you probably want to take more time producing your collection of work images in a book.
