Very cool stuff, I've long thought there must be some fancy ways to get extra information for better image resolution by taking advantage of the other cameras.
That said, I must also say that most of the side-by-side comparison photos shown here are somewhat impressive, and in some cases, the photosynthesis one just looks worse to my untrained eye.

I'll choose to take this as evidence of the fact that you're tacking a very difficult problem, and you're also being honest in your comparisons and not cherry-picking too aggressively.
Some of the photosynthesis zoom-ins have overlays take a bit longer to load at higher resolution.
As dole alluded to below, I have been going back and forth in balancing the quality of the example pictures with the data load. I've pushed an update to the site now that weighs much more towards quality for this exact reason! But you're right, I don't want to hide the fact that not all results are perfect.
