ADOBE, PLEASE, FIX THAT BUGS! ADD ACCURATE PERSPECTIVE MATCH TOOL! PS calculates horizontal field of view wrong, IT'S A BUG!!! See the proof. As you see PS says us that in this canvas size we've got a horizontal FOV like 75 and vertical 30. But it's a mistake. The real Horizontal FOV must be 67.6 The simple formula proves it canvas width w = 5000 pixels canvas height h = 2000 pixels d = 3732,73 (distance to the center of projection) Horizontal FOV 2 tan-1 ( w / 2d ) = 67.6 Vertical FOV 2 tan-1 ( h / 2d ) = 30 So if you try to save an image from PS and then create the same canvas size in Adobe Dimension CC or in any other proper application and use the saved image from PS as a background, then will put camera FOV 75 degrees you will certainly see that perspective of this cube will not match. But if you put in FOV the value like we've got in the formula above (67.6 degrees) the perspective will fully match because it's correct, it's simple trigonometry.

Photoshop can't determine the real perspective camera parametres frome the image. There is simply no any accurate tool. The vanishing point filter has problems with the FOV too. Just to try to create in PS some 3d layer and then use VP filter to reconstruct camera parametres just created)) You will see the wrong FOV. Basically that means that Adobe users haven't opportunity to add something to a real photo using any of ADOBE applications. How can it be in 2019? Comparing with the Sketchup I can determine an image perspective in minutes but if in Photoshop I must do it manually, using knowleges of geometry, of course if I want to get accurate results. Look at this situation from such a point of view. Don't you think it's a weird thing? A user pays each year for Adobe applications and if he wants to add some object to a real photo he can't do it correctly with the help of Adobe products. For example he brought Adobe PS and Dimension. So he has a task to render some object in Dimension CC and put it into a real photo. What tool should he use to get an accurate results in perspective matching in order a rendered object match the real photo perspective? The answer is NO ONE tool here presents for now! He has to take a calculator and remember a school trigonometry formulas to exactly compute the perspective from any photo while other users could do the same via automatic tools of perspective matching in Sketchup, 3ds Max, etc. which works properly and could get accurate resuls in few minutes, they just need to show the application a group of parallel lines and that's all, the resulst mostly will be fully match.
