KR is a knucklehead.
This is my post on a diferent forum...
Quote: Ken has a habit of painting (very loudly and obnoxiously at times) with too broad a brush. For example, he goes on and on about how megapixels don't matter. And while there's some truth to that, he NEVER considers the fact that some people may do a significant amount of cropping and that others may want to print poster-size pics.
He also believes there is no advantage in using RAW, and thinks people who "fiddle" with images are stupid.
I'm sorry I had to go to his page to get this...
RAW vs JPG
Here are a few snips...
1. "Some fancier cameras save this raw data so you can use software to do the same thing the camera's hardware did, later. Software takes much longer to do the same thing the camera's hardware does, but gives less confident people the chance to try to fix mistakes later.
Image quality is the same in JPG and raw. See my D200 Image Quality Setting Examples. See also my explanation of File Formats."
2a. "The quality is the same for almost all intents and purposes as raw, and the raw files would take gigabytes or tens of gigabytes and resultant hours to download, convert, catalog and burn to backup CDs. In fact, if you shoot this much then >>>JPG can give better quality<<< since attempting to shoot this much raw will constipate your workflow and you >>>>could miss making some images<<< entirely as your cards fill up. You'd always be running out of memory cards or time waiting for the acess light to stop blinking."
Idiot. Volume does not equal quality.
2b. If you love to tweak your images one-by one and shoot less than about a hundred shots at a time than raw could be for you. In fact, if you prefer the look you can get from raw (it may be different from JPG in some cases depending on software) you can let your computer batch process images and save the results as JPGs, too. I almost never shoot anything in raw, and when I do I never see any difference for all the effort I wasted anyway. (I can see differences if I blow things up to 100% or bigger on my computer, but not in prints.)"
So now there is a difference in "look", but not "image quality"...
3. "I take a lot of flack from tweakers because I, like other photographers, prefer to make my adjustments in-camera and use the JPGs directly. Others prefer to spend even more time later twiddling in raw, but that's not for me. I get the look I need with JPGs and prefer to spend my time making more photos. If you're the sort of person who likes to twiddle and redo than by all means raw is for you."
I don't like going overboard with processing, but Ken is offensive and out-of-date, despite or because of his (let me quote)...
"three decades of continuous full-time paid professional experience in digital imaging. In addition I was studying digital imaging for ten years before I got my engineering degree and started as a professional working with the guys with PhDs in mathematics who invented all this."
Probably hangs out with Al Gore and (a particularly goofy and clueless poster).
and finally....
"D40 is twice as sensitive to light as the D40x and D80. (The D40's ISO defaults to ISO 200 instead of the less sensitive ISO 100, making for sharper photos in any light.) "
