Rockwell on DSLR vs. P&S

My buddy, Ken Rockwell, did a recent comparison of high-ISO
performance between DSLRs that can be found he
http://kenrockwell.com/tech/iso-comp...7-10/index.htm

Note what he says about the Point & Shoots near the end of the
article:

"I was too lazy to include a compact camera, which as I showed last
year, is abysmal compared to any DSLR. A typical compact camera, like
the Canon SD700 I use all the time, is ten times worse than any DSLR.
My SD700 at its lowest ISO 80 looks about the same as any of these
DSLRs at ISO 800! "

LOL! Even Ken Rockwell says, "Sucks to be you, Point and ****ters !!!"

No he doesn't!

You've got to hand it to Ken for being consistent.

For the best advice from a true professional see:

I think he's the guy with numerous nicks arguing for the P&S
lobby.

Yes, I guess he assumes no one actually reads his crap.
I would have thought it was a fairly safe assumption, but then you go and
prove him wrong! :-)

We've got to hand it to you for being ironic.

If Ken Rockwell had used a better downsampling algorithm,
rather than Photoshop bicubic (I'm assuming), maybe just maybe
the DSLR image would look better than the P&S digicam image.

I would like to know, what are the better downsamplers?

At whole-fraction scaling factors (25%, 33%, 50%, 67%, 75%)
most downsampling algorithms give identical results.

Otherwise Lanczos is far better than Bicubic for most images.
Lanczos leaves smooth areas smooth and keeps edges sharp.

It's possible Bicubic is good if you're changing aspect ratio
(different scale for x / y). I have not investigated.

OK thanks for the reply! I guess the closest I've got to Lanczos is Irfanview
and xnview. But I've read that Irfanview's version is not the whole version
that is installed in a software program, PhotoLine32 has it full versioned,
written in Germany. I am not gonna buy it.

And this from the greatest fan he has??? LOL with that lot.

Unfortunately, in this post, Rockwell does not SHOW any comparisons
between P/S and DSLRs. "I was too lazy....." is a pitiful cop out.
He sounds like G.W. Bush...."Trust me folks"...if I had included a P/S
picture it would have been crappier than the DSLR pix.
Actually, a P/S image taken at ISO 400+ WOULD look crappier than a
similar pic taken at 400+ with a DSLR, but I suspect the difference in
image quality between a P/S and a DSLR at ISO 80 would be minuscule.

Roger Clark has posted a good comparison pic on his site.
