Upgrading to the Max Pro RAW plan is easy!
From My Account, you’ll see a banner Upgrade to Max at the bottom and on the top right side of the page.
Clicking on either will bring you to the Payment page. On the Payment page, you’ll see the breakdown of the price. You’ll see the total cost of the subscription, the amount of credit you'll receive from your current subscription, and the total you'll be charged for the upgrade.
When your account renews it will renew for the total cost of the Max Pro RAW/LOG subscription.
