Appreciate the comments Rob. I'd be curious to know what Paul Stenquist sees on his new 5K Mac display. (See original post in this thread, if you are wanting a diversion, Paul). Just a guess, but I think he may see more than "subtle" differences.
Regarding your 2nd paragraph, it would be difficult to duplicate PSR with just 4 shots. I'm no statistician, but PSR overcomes the Bayer array with its 4 precise shots. Simply put, taking a theoretical pixelsite-sized section of your overall image, any handheld shot you take has a 50% chance of being a green one, a 25% chance of being a red one, and a 25% chance of being a blue one. That does not equal 100% chance of getting that exact distribution with 4 random handheld shots. Also, you are going to have to deal with any subject movement from the time you take your first exposure to the time you end your last one (same problem for PSR). In any event, the point is that the camera takes care of your exercise FOR you. You don't HAVE to do the tedious combination of separate images that you describe. The camera does it for you. Although you can work with the huge RAW file yourself, if you wish. I have yet to experiment with that. That being said, I'd be interested in seeing what a burst of 8 shots at 8 fps would look like compared to PSR. Might have to put that on my list of things to do, unless someone beats me to it.
