Parts of the red hats and Che flag are 100% in the red channel. But
nowhere near as much as in Phil's recent examples. Those look 1/3
stop overexposed to me...

Yeah, that would have to be one of the all-time best. :-)

Say, as you can probably tell, anticipation is high for your upcoming e-book on the F707 in a few short days (Sept 15th)

And I just noticed that it is also going to include the F717. Great!

and boy, you can really see the red clipping. Check out the drop
near the middle.

Great tip. It shows me how little clipping can be seen in the red channels of properly exposed images. In fact, my red flag series of a strike in Rome where large Che flags were being waved show up in Photoshop as being clipped at 255 red in many places. But the plot shows remaining detail here.

Nice sharp details...other than the reds>

Yikes!

That looks like something beyond, or in addition to, clipping.
Would that be called fringing?

Oops. Just did a little research here on the website and I think I answered my own question. It's "blooming," isn't it?

Hmmm. I wonder why some of these red flowers aren't blooming.

that could be jpeg compression rearing it's ugly head. it's particularly bad with red/black contrasts, like the ones on your photo. that f707 has a predilection for clipping reds doesn't exactly help.

test it out in photoshop - create a bright red text layer on a black background and then try to save it as a jpg. you will see that you will have to reduce the compression a lot to avoid smudging.

jpg is not exactly great for contrasty details, but it's still the most efficient comrpession method out there.

Aftyer looking at the original again I do believe you are right. Resizing and compression have affected it, but definetily more in the reds.

I have to deal with this same issue when shooting soccer pictures of teams with black lettering on red uniforms. The detail is completely lost. It simply looks out of focus but it's not.

I know this is primarily due to the mosaic pattern on the CCD and the loss of detail due to only one third of the pixels having any useful information. (Just the red ones)

The same thing does not occur with white lettering on Red uniforms, though some "bleeding" onto the white does happen.
