and in english this all means??? ÉÍREman 16:16 May 6, 2003 (UTC)

Indeed. I've had a go at a clearer intro, but I'm not happy with it. I hope someone else can improve it. The problem is that it's very hard to say what a pixel is: screen element; printing; part of a digital image. Though in the last case we're strictly dealing with texels; but only the 3D gaming industry makes that distinction AFAIK -- Tarquin 16:30 May 6, 2003 (UTC)

I'm a historian whole technical skills are such that if I change a light bulb I am likely to black out all of North Dublin, so I am afraid the article went completely over my head, but then anything technical does anyway. But then I suppose people people are are technologically literate might find the stuff I write on historiography or royal naming procedures over their heads too. Each to his or her own! I notice BTW that an earlier version mentioned a mac's 'thousands' and 'millions' in term of screen colours, so I learned something about what that actually means on my eMac. Except that that info was culled from later versions!!! I decided to check just what the hell pixel was because I bought a new digital camera that uses 3.2 million pixels so I was hoping to find out what it was I had bought. The joys of being technologically illiterate! ÉÍREman 19:44 May 6, 2003 (UTC)

Very nice picture, Tarquin! I'm even willing to overlook the fact that the lines connect the wrong corners. ;) -- John Owens 21:41 May 6, 2003 (UTC)

dang! I'll fix it later. -- Tarquin (boy am I glad I always keep my layered photoshop documents!)

I'm a bit put off by: " This can be expressed as a single total,", because it seems to me the single number is a product, not a total... but I can't see how to change it without making it too complicated -- Tarquin 21:48 May 6, 2003 (UTC)

Is this the bit that now reads "For depths larger than 8 bits, the number is the total of the three RGB ..."? If so, I agree that total is the wrong word, but describing it in a way that a non computer-literate person will immediately grasp is difficult. Perhaps something along the lines of "For depths larger than 8 bits, the bits themselves are divided into three seperate values that describe the intensities of the red, green, and blue components of the desired colour.", since the values are not really either a product or total.

I added a section on what a digital camera "megapixel" REALLY is, and also added sections for pels and sub-pixels.

On the digicam megapixel subject, I sent an email to the apparent author of http://megamyth.homestead.com, asking him to contribute to the subject. Scott McNay 07:45, 2004 Feb 8 (UTC)

On another subject, can someone clarify several issues? I'd like to know:

whether a "dot pitch" is the same as the pixel size, as loudly implied by this article, and not clarified at all by the dot pitch article?

how "native resolution" (often seen in relation to LCDs) relates.

whether "native resolution" applies to CRTs or not (which is implied by this article in the sub-pixel section), at least for horizontal resolution.

How CRTs and LCDs display different horizontal resolutions when they have embedded color masks, and ditto for vertical resolution for LCDs.
