Jagged (stepped) diagonals (参见link,虽然出现机率不高,但感觉非常不爽)

It occurs on diagonal lines which are not quite at 45 degrees, these lines are then 'made up' of groups of pixels in a 45 degree line, stepped one pixel and then repeated. This can be attributed to either a problem with the Bayer interpolation algorithm or sharpening algorithm. They exists also in RAW images converted using the supplied acquire module or RAW file converter. You can clearly see this pattern in the examples below (magnified 200%).

It's unlikely these artifacts would be visible on a printed page or computer monitor (and normal viewing sizes) but they are there, and noted.

  • 枫下沙龙 / 休闲娱乐 / 大家来看看这个数码相机,朋友去Hawaii的照片。不爱相机的就看看照片吧。:P
    • 真美,不过我不懂,得问LG。 什么型号的?谢谢。
      • Sony DSC S85. 我刚知道的,我这个穷人就不想了。555
        • LG说1340. 太贵了。只能推荐给EGG了。
        • 要不咱们组个团去夏威夷直接看去得了。
          • 我报名.可惜我不能把所有的图都贴来(有人在),有很多海的,山的,火山的,热带雨林的都没发让大家欣赏了.我去过古巴,加勒比的海滩似乎比hawaii的好,但是只有海滩,没有别的.可惜我的照相技术太次,就不贴上来比较了.
    • 看了照片,风景狠美,照得也很好。不过从清晰度的角度看我还是推崇canon G1/G2. 参见这个网页。当然人家可能作了处理。canon 的ISO 50 and RAW图像格式狠不错。价格近似的话当然选G2.
      • 偶同意,不买995了,改G2。不过偶挺担心它好象有一个diagonal line artifacts BUG。你这些照片,好象都有意避开了。不知道,这个BUG 解决了吗?
        • 偶都不知道有这个BUG, sorry.

        • 我的G2基本上在高反差时候,在四个角有紫边,有软件可以清除。
          • 对不起,你说的是Purple Fringing 又叫(Chromatic Aberrations),两码事。Canon G2的Purple Fringing解决的算是比较好的,你还没看其他的相机效果呢。
      • 那个提供照片的朋友同时也用过G1,他说SONY的"VIDEO FUNCTION IS VERY POOER". 和G1的"fresh light is not strong enough"是美中不足的.不是我说的,我连这两款的壳都没有摸过,不要抛砖(板)喔.
    • where can i find futureshop? i want to buy one DC, canon G2 or nikon995, which is better?3x
      • 价钱是995,如果不考虑钱,应该就是G2了,新出的CP5000同G2有得一比。
        • 多谢。请问futureshop 的具体地点?地图上怎么没有?
          • Warden/Eglinton, Kennedy/HW7, Kennedy/Elsmile(CHK spelling), Eglinton/Downvalley? a lot
          • 查下面这个Link
