You don't need anywhere near 6 MP for TV viewing. Good point though.
Clyde If I were designing DSLRs for the prosumer market (with the current 3:2 ratio) the sensor would be 3840x2560 pixels (9.86 megapixels) and as large as needed (up to full frame) for excellent dynamic range. I believe in the near? future most consumers will view photos on true HDTV sets at 1080p resolution (1920x1080) so I sized the sensor at exactly twice the pixel width of the HDTV standard. 3840x2160 (16:9 ratio - 8.3 mp) would be a good sized option for landscape photos. Easy to lossless resize (divides by 16 for jpeg) to view on HDTV and also large enough for most prints. There are many other changes I would also make to DSLRs... but that's for another thread.

I would resize the sensors to be ISO 216 "A" proportional so that printing could be a cropless process regardless of the "A" sized paper chosen. Another alternate would be golden section ratio. The reality is that sensor dimensions are mostly driven by addressing logic issues/efficiencies.

I agree with the A-series of sizes; the aspect ratio of these (1.414:1) is almost exactly midway between current camera ratios of 4:3 (1.33:1) and 3:2 (1.5:1). The Golden Mean has a ratio of (Phi:1) or (1.618:1) which may be ok for landscapes but is too narrow for portait orientation. Scholars have pointed out the extensive use of the Golden Mean in classical art, but it applies to figures and constructions within the picture, and not to the overall aspect ratio of the artwork. Nitpick: English usage would prefer 'alternative' to 'alternate' in your sentence above. You are slipping into American usage, Alan {:-) Colin |

I'd dispute that as a 'requirement'; eg: IMO the G-section may apply to the boundaries of the work as well as relationships in the work. Nitpick: English usage would prefer 'alternative' to 'alternate' in your sentence above. You are slipping into American usage, Alan {:-) Yes. Most of out television (not that I watch a lot) is US. I speak French half the time and English the other 2/3. It's harder and harder to be correct in any language, esp. Japanese which I don't speak at all. In about 2025, under President Jenna Bush, the US will invade Canada for our fresh water, oil, wood, minerals, hydro power and Poutine. They will learn, finally, that Starbucks is really not that good compared to the great variety of coffee shops that have been in Montreal for well over a century. So I'm just getting ready by letting my English decay. The other day I actually said "zee" instead of "zed" while spelling a word for my son. At that, the word was "criticise". It's too late to save me. I don't spell color 'colour' anymore, but I still seem to be stuck on cheque.

Well, I have to admit that my spelling at least does change depending on the perceived audience. In this predominantly American group I spell it 'color' and 'check' and 'criticize' just to be in the swim, so to speak - that's if the participants are US-bred. OTOH if I am replying to Commonwealth-bred types, I use proper English. (ducking for cover here ....) Come to think about it, I dunno why I do that - maybe I'll stick with Queen's English from here on {:-) Colin |

What I'd really like to see most is greater color depth, drastically improved dynamic range, and greater user programmability. I'm not sure it's possible to see greater colour depth. Digital cameras in RAW mode are already good for a very wide gamut, and the loss of colour happens later in the chain. Andrew. |

Try going to a Subway and asking for "capsicum" on your sandwich - you will go hungry that day. On the topic of language - it is eroding quickly and the internet is accelerating the erosion, with its short-hand speak and acronyms (IMHO ;-) Musty. |
