How do you find right plane/perspective to place a product on a photo?

Someone on GD.SE commented that I don’t know how light and perspective works. Moreover, the product I placed here near plant is in wrong plane.

How do I know if it’s right or wrong plane and perspective? Is there any way so we can know how should you take the picture that fits perfectly in terms of plane and perspective, here?

PS: I know the shadow angle is not right. I got to know about this in this question. Now the question is about finding right perspective and right angle, like:

a) If the box was actually a part of this photo, would the top face of box be more visible or less than present

b) Is the actual photo taken from a more distance than the distance used for taking photo for box. In other words, is the photo of box taken from too close or too far distance

c) Should the bottom/top of box have been narrower/wider than the other end

If you can’t understand, please comment, I’ll edit again.

Hello

Answer

Someone on GD.SE commented that I don’t know how light and perspective works. Moreover, the product I placed here near plant is in wrong plane.

In this scene, the viewer has the perception of looking slightly down onto the bench top. In other words, the horizon, if you could see it, would be high in the image. So the top face of the box, sitting well below the horizon, should be visible, even if only slightly.

edit: the horizon, in two-point perspective, is the place where perspective lines converge. The bottom edge of the box is doing a acceptable job of matching the scene:

image with horizon

But perspective lines extended from the top of the box don’t match. The red lines should meet at the triangle corners.

It’s hard to make a convincing image without guides. Corrected perspective lines to aim for:

Not easily.

But if you can reshoot the scene (and not the box), then try and lower the camera to be in line with where top of the box would be. Use a dummy box if possible.

If you can reshoot the box (and not the scene), raise the camera to show more of the top face of the box.

You should expect to test a few angles until you find the right one, so leave the camera in place while you do a test composite, to make it easier to find the right angle.

b) Is the actual photo taken from a more distance than the distance used for taking photo for box. In other words, is the photo of box taken from too close or too far distance

The camera is too close to the box, because the difference in perspective between the top and bottom faces is more extreme than in the scene.
