A Quick & Simple Pseudo-3D Render via Photoshop
The assignment: create an image showing some particular logos together for a PowerPoint slide.

The only logo that I created here was the Regents seal in the very center… the other two circular seals to the left and right were delivered to me as .jpeg files, so they had to be cut out (they were in white boxes, as it were). I added the border around the LCTCS banner for contrast.
For the logos and seals on top (as opposed to the reflections), I stick with the “Perspective” tool under Image>Adjust>Free Transform.
After tweaking everything, I created the blue tabletop by using the polygon “straight-line” lasso and filling it with the cyan you see above.
I grouped the logos together, duplicated that group, flipped them upside down, and used the Distort and Perspective tools under Free Transform.
For PowerPoint, I typically export at 1024 x 768, as a PNG-24 with transparency (the version of this image used in the presentation is actually see-through in the upper white areas). PowerPoint does a surprisingly good job of supporting PNG files with varying levels of transparency (even transparencies that go from 100% to 0% opacity).
