- Instant Download images and purchased “instantly” using Download Credits which can be purchased in blocks. The larger the block of Download Credits you purchased the greater the discount (up to 25%)!
- Digital Proofs are added to your shopping cart just like traditional prints and provide the opportunity to add retouching services like blemish removal and a whole lot more.
