A few things I would do (and have done for microscope shots). First is to use a black solid and mask a circle to reveal the image (cheesy, but it sells the shot). Next, take the image and rotate it in Z space slightly. Then use an A.E. camera and animate the focus so it actually does a rack focus. At the same time have a slight directional blur follow the rack, and slightly adjust the exposure. Use Au Naturel for both the blur and exposure, it’s exposure adjustment is worth the $99 by it self. As you can probably see, I’m a big fan of lots of little tweaks and slight adjustments. “Reality” is all about the minute, we might as be the same.
