HIGH FIDELITY VISUALS
Most modern day work is done in sketch or other variations of similar design softwares. This has resulted in a lot of what i would call, high fidelity documents. These images, show more than just placement and can be an easier way to sell concepts to clients and business sponsors.
PRO: Visuals can easily be transferred into prototypes through tools like Invision. This saves time and gets more realistic user testing results.
CON: A problem presenting with these is the fact that some people get stuck on colors and wording. When the need might have just been to talk about the overall experience.
So I’d suggest using these appropriately, depending on what you want from a presentation and how you are using these.
