 Until today, I didn’t realise how important it is to brainstorm your idea,

using sub-conscious mind bringing your idead to next level.

And another interesting of doing it was called,

exquisite corpse

It is really interesting idea as well and I’ll try to apply for my next idea generation.

I was an hour late for today’s class, so I missed most of the stuff.

Luckily, Gaye put down the name of the artist to visit her site later.

I’m not really familiar with photography and its concepts but surely, the “Welcome to Sydney” caught my attention as I browse through her website.

When I think about Sydney, Opera house and Harbour bridge crowded shitty place comes to my mind first.

And when I think back, all the images about Sydney that I saw in Sydney airport was mostly about those two things I mentioned. (Of course, let’s not forget about Kangaroos and Koalas)

It kind of broke the old rules and images of Sydney and looked at the city from another side.

Really nice work and concept and the best part is it works!!

(Talking about being multi-culture and globalization, I remember a comedian saying, in the end there aren’t going to be any white, black, yellow people on earth. They’ll all be brown color, so why be racist?!)

The basics of PAL and the NTSC system are very similar; a quadrature amplitude modulated subcarrier (typically at approximately 4.43 MHz for PAL, and 3.58 MHz for NTSC) carrying the chrominance information is added to the luminance video signal to form a composite video baseband signal (CVBS). The SECAM system, on the other hand, uses a frequency modulation scheme on its colour subcarrier. The name “Phase Alternating Line” describes the way that the phase of part of the colour information on the video signal is reversed with each line, which automatically corrects phase errors in the transmission of the signal by cancelling them out. (Lines where the colour phase is reversed compared to NTSC are often called PAL or phase-alternation lines, which justifies one of the expansions of the acronym, while the other lines are called NTSC lines.) Early PAL receivers relied on the imperfections of the human eye to do that canceling, however this resulted in a comb-like effect on stronger phase errors. Thus, most receivers use a delay line which stores the received colour information on each line of display; an average of the colour information of the current line and that of the previous line is then used to drive the picture tube. This reduces vertical colour resolution compared to the NTSC system, however since the human retina also has a colour resolution that is much lower than its brightness resolution, this effect is not visible. NTSC, PAL, and SECAM all have chrominance bandwidth (horizontal colour detail) reduced greatly compared to the luminance signal anyway.

NTSC receivers have a tint control to perform that correction manually. Some engineers jokingly expand NTSC to “Never Twice the Same Colour” or “Not the Same Colour” while referring to PAL as “Perfect At Last”, “Peace At Last”, or “Pay for Additional Luxury”! However, the alternation of colour information—Hanover bars—can lead to picture grain on pictures with extreme phase errors even in PAL systems, causing some engineers to alternately expand PAL to “Picture Always Lousy” or “Pretty Awful Looking”. Another expansion is “Pay Another Licence” in reference to the British television licence fee which is higher for colour sets.

The PAL colour system is usually used with a video format that has 625 lines per frame (576 visible lines, the rest being used for other information such as sync data and captioning) and a refresh rate of 50 interlaced fields per second (or 25 full frames per second), such as systems B, G, H, I, and N (see broadcast television systems for the technical details of each format). Some countries in Eastern Europe which formerly used SECAM with systems D and K have switched to PAL while leaving other aspects of their video system the same. (However, some other countries changed completely from SECAM-D/K to PAL-B/G.) In Brazil, PAL is used in conjunction with the 525 line, 29.97 frame/s system M, using (very nearly) the NTSC colour subcarrier frequency. Almost all other countries using system M use NTSC. In Argentina, Paraguay and Uruguay, PAL is used with the standard 625 line system, but again with (very nearly) the NTSC colour subcarrier frequency (3.58 MHz); these variants are called PAL-N and PAL-NC. Recently manufactured PAL television receivers can typically decode all of these systems except, in some cases, PAL-M and PAL-N. Many of them can also receive Eastern European and Middle Eastern SECAM, though usually not French SECAM, unless they are made for the French market. Many of them can also accept baseband NTSC-M, such as from a VCR or game console, though not usually broadcast NTSC.

The PAL colour system (either baseband or with any RF system, with the normal 4.43 MHz subcarrier unlike PAL-M) can also be applied to an NTSC-like 525-line (480i) picture to form what is often known as “PAL-60″ (sometimes “PAL-60/525″). This is often used in applications such as playing NTSC video tapes on compatible PAL VCRs, playing NTSC DVD-Video, and video games, as most modern PAL television sets can handle this kind of signal without too many issues — standard NTSC-3.58 support is less common (though more recent sets support it) and often results in a black-and-white picture when viewed on a PAL TV set. However, this issue (the lack of colour, or having to convert the video to PAL-60) is easily solved by using RGB connections through SCART cables, which are very common in Europe.

When video is transmitted baseband, most of the differences between the “one-letter” systems are no longer significant, other than vertical resolution and frame rate, and in that context, unqualified PAL invariably means 576 lines at 25 frames per second, interlaced, with PAL colour. In digital video applications, such as DVDs and digital broadcasting, even the colour encoding is no longer significant; in that context, PAL means only 576 lines at 25 frames per second interlaced, and there is no longer any difference to SÉCAM.

Err.. Ok, I’ve read it, but I don’t quite get it.

I think, as long as I can see color images on color TV, it doesn’t really matter to me.

So, let’s forget about getting information on NTSC.
