Aye, going out and actually doing some photography is so much more fun than all the tech talk. ;P

Thanks for all the insight. You seem to be more obsessed with all of this stuff than I am.

I found another article that totally backed up your claims about diffraction:

Here are some of the results of natures latest call:

Totally agreed about well size. I thought that was one of the benefits of going to a larger sensor. If we take the 18mp 60D sensor, and the 21mp 5D sensor

arn't the 5D photosite wells larger?

which is partly what gives it better ISO performance?

The obsession comes from my somewhat related background (CMPE) and the desire to work on stuff like that.

Those are some awesome shots. I really like #2 and #3. I want to get more into landscape photography but, alas, MD kinda sucks and I don't currently have the time to drive.

About well size, I meant more about capacity and not size. For the same capacity, a larger well will actually fill up quicker since on average each photosite will get more photons.

As for the 5D having better ISO performance, I wouldn't necessarily conclude that it is because of the larger wells because the sensor captures more light as a full frame. If we compare two APS-C's, then we might be able to find a trend on well photosite size. But there's just so many variables that we can never know in each sensor design.

Back to resolution, there is always software solutions! This looks really interesting, with one non-matlab implementation:

Super-resolution

Super-resolution (SR) are techniques that enhance the resolution of an imaging system. Some SR techniques break the diffraction-limit of systems, while other SR techniques improve over the resolution of digital imaging sensor. There are both single-frame and multiple-frame variants of SR. Multiple-frame SR use the sub-pixel shifts between multiple low resolution images of the same scene. They create an improved resolution image fusing information from all low resolution images, and the created higher resolution images are better descriptions of the scene. Single frame SR methods attemp...
