i think I will mainly use your test chart as a poster , cool lol

先要你有夠高解像printer, 碌左出來再用相機影, 先知道結果, 不過市面上inkjet或laser都冇咁hi res, 可能要拎去出3600dpi菲林先勉強得, 俾貴少少出4800dpi啦

O?
wonder where can i get it printed...
but the pdf itself is only 72 dpi, can it enlarge that much to 4800dpi...

So print the chart:

Do the tests:

maximilianyuen, 你同d2c個pdf都係vector來, 個printer有幾高res. 就print到幾多, postscript printer比較好d

在死黑死白下看鏡頭解像力,如果將黑綫轉為不同程度的綠色或肉色,情況及結果可否一樣呢?

[kingkonghk]

照計係一樣, 不過黑白對比大, 容易觀察好多之嘛
