Web Page Mocks
Of course THIS website* that you are on right now I mocked up and prototyped in Adobe XD as you can see from the canvas below. :-)
But before I experienced the glory of Adobe XD and InDesign, I often used Photoshop for web site page mocks.
In this example, I am showing standard elements of a case study and how the page would behave when scrolled.
Thank goodness for prototyping tools! Productivity is much accelerated and it is SO much easier to collaborate now.
*Then I actually built this site using WordPress.
