6年前外國有神人將SCANNER 變左做數碼機背

有冇師兄想挑戰下?

Scanners are really extra-large image sensors at heart, so it stands to reason that you could make a decent camera out of one. Right? Well, Dario Morelli just proved it... and then some. His homebrew medium format camera uses parts from an Epson V30-series scanner to take enormous 143-megapixel photos whose resolution puts even the better professional cameras to shame. Morelli went so far as to repackage everything in a custom enclosure, so the device is relatively portable and will sit on a tripod.

The catch, as you might suspect, is that this camera still behaves like a document reader while you're shooting. You need to connect to a computer and a big external battery to get anything done, and there's no live viewfinder to help you frame the shot. An exposure typically takes minutes rather than seconds, and the limited light sensitivity (Morelli believes it can manage ISO 50 and eight dynamic range stops) largely rules out nighttime photography. But hey, it works -- and it's proof that do-it-yourself cameras can sometimes best their professionally-made counterparts.

直接買db啦又唔係貴....

問題在時間, 唔計處理, scanner 係 "遂行"掃描, 由一行移去別一行, 有啲組件要移動 (反光鏡 or CCD).

一般小型 scanner 約要10~30s 掃晒A4(11.75寸).  將低片減平 (6x7), 6寸都要 5~15s.

影景, 要無風無雲至好.
影人, 要個人唔郁至得

Phaseone一個背都7萬幾吧

咁又係,
而家平平地 scanner 都 1200 dpi, 即 1.44M/i^2 , 6x7 有60.48MP,
如果 6x9 或8*12 就更正

    從來都有間叫  BETTERLIGHT 做 scanning back 都係博物館用黎做 archive. 最高做到384MP.
     http://www.betterlight.com/index.html
     另外 LEICA 第一部數碼機 S1 都係 scanning back.
     之前都花些少時間研究過. DIY scanning back 最難係編程 始終 scanner 曝光參數設定唔容易破解.

以前玩過6x17 scanning back 玩左一排 果斷上5x7 用db影 比scanning back好n倍
