Exactly right! This is the way every web development companies following.
UX and graphics designs were similar. If you are good in photoshop design, then you can design UX as well.
When compared with graphics design, UX designer have high demand in market.
That is a ton of misinformation.
UX design and graphic design are not similar. UX design has nothing to do with graphics in the first place - it's User Experience design and has a ton of work on it. It's practically a science in itself.
Once approved, the UX flow is converted into a UI which is User Interface - which is then turned into code.
They may start at the same base tools, but they're two very different outcomes. It's like saying a mason and a sculptor are the same thing because they use the same tools.
Graphic designers mostly work with print media, logos, branding and have a prominence in the advertising industry. They have an acute sense of design and are mostly great artists on paper. They use software like Adobe Illustrator or Corel Draw or Adobe Indesign. They understand Print, they understand packaging, they understand display, they understand banners.
While UX and UI - it goes in a different tangent. Understanding User experience includes writing user stories (their flow from one end of the application to another and back) These are then added to a prototyping tool such as
Balsamiq, and once approved are handed to a UI artist who works in converting them into screens. Each screen is then sliced and then used for development.
If you're interested in UX design - there are several tools to use.
Also, Photoshop is no longer the only tools available for designing websites and apps - there's Sketch, there's Adobe XD, Figma etc. that is being used more and more in the industry.
