I have questions to get kind full answers. I see the marketplace have lot of graphic mock-ups with making photoshop. I need to know their use of any advance plug-ins or filters to make them 100% realistic?
I definitely think you should be considering InDesign and/or Illustrator as well as Photoshop for this type of product.
In most cases I doubt you need extra plugins etc.
For a mockup to look its best, you should be using well lit professional photos which you take yourself, or even 3D models with special attention to detail. Then it’s a matter of setting up the layers and effects to help seamlessly blend their images into the photos with minimal effort on the users side. There’s no real automatic trick/plugin/filter which lets you create mockups on the fly.
One thing to keep in mind is that imperfections make things more believable, such as photo grain, symmetry (and slight lack of it), maybe a subtle finger print catching light on the side of a glass, etc. Though at the same time, you don’t want to overdo it, the imperfections need to be subtle, so the mockup still looks perfect.
hi photoshop, of course and possibly illustrator or cinema 4d if u have skills enough, optionally indesign … but photoshop is the basis
