Either you make a perfect digital fake image, or you go for a less ambitious slide layout. I laugh when you seen an obvious Photoshop mistake, I cringe when I see a 95% correct image. “Something is not right”
In the image above, the light on the cars, the camera angles, something is not working. Ultra high definition monitors now also give away the artificial digital backgrounds of movies.
In a few years time, software will have solved this problem. Until then, your presentation slides, web sites, and other marketing material will look like the work of a young kid who slowly starts to add the 3rd dimensions to its drawings. (In the early years children do not actively notice the concept of perspective, and things getting smaller towards the horizon).
