camera any time soon.
Update on sensor size
Most people seem to think the sensor size is actually 1/1.5″, which is
still larger than the Nikon 1, yet smaller than m4/3.
Canon PowerShot G1X
Canon U.S.A. is unveiling two PowerShot Elph-series point-and-shoot cameras
and a new flagship Power-Shot G-series model. The G1X (shipping in February

new high-end SLR lens product line specially designed for high resolution,
full frame DSLR cameras with resolution more than 30MP (Nikon D800, D800E):

We should start with my recent review of the Sigma DP2 Merrill (DP2M). If

camera is actually understated. The DP2M may have the highest per-pixel

The smaller-sized images out of the 5D Mark III are spectacular. They are
much, much sharper and cleaner than images from cameras on which that is
their native resolution. When you start with over 20MP, it looks pretty good
if you use all those to make 11MP or 5MP.
Why? Because they use less, or no, Bayer interpolation. No digital camera
really resolves its rated resolution; they cheat and interpolate up, so at
100% at its rated resolution, no digital camera image is as sharp as a true

reference resolution equal to 8 Megapixels. 这个还能有其他解释嘛?
之所以用的N0, 没有写8MP, 因为这个8mp是个任意值, 具体选8mp, 还是9mp, 7mp, 没
有区别,只要统一就行, 都是一个reference resolution值而已, 而这个reference

发帖数: 5876 | 7 对, dxo解释了normalized后SNR和absolute SNR的区别. dxo的结论是对于比较不同相
机的高感, 是"only normalized results are relevant." 也就是只有normalized后
SNR才有意义. absolute SNR是irrelevant的.
版上这么多童鞋都采用了dxo的sensor测试结果, 为什么就不理解dxo的测试方法呢?
如果不理解dxo的测试方法, 那么dxo的sensor测试结果就完全没有意义
dxo给了数学公式的计算的normalized的结果,
"What should be remembered is that doubling the resolution adds:
3dB to the normalized SNR
0.5 bit to the normalized DR
0.5 bit to the normalized TR
1.5 bit to the normalized CS.

这个公式很清楚了,就是说:

发帖数: 396 | 12 网上有很多方法。我的一点经验是，大光圈头跑不跑焦很明显，直接调就行。小光圈头
跑不跑焦是统计意义上的 ：即使对焦偏一点，也有相当比例的照片很锐。对焦偏得越
远，完全对上焦的照片几率越小。偏到一定程度，照片就明显糊掉了。网上最极端的做法
是对每个微调值拍resolution chart，计算resolution，然后画出resolution对微调值
的曲线，再用二次曲线拟合，找到对应resolution最高的微调值。我觉得这个方法虽然准
确，但太费力也太overkill了。我的方法是看微调+， -多少糊掉的程度和几率差不多
，然后取中值作为微调值。
你搜一下也许能找到一些更有效的方法。 |

从PRC国庆到US鬼节
1989年10月1日前夕，上海市府举办招待酒会，庆祝PRC 建国40周年。来宾中有美
国驻上海总领事。原上海复旦大学校长谢希德，在招待酒会上主动问美国总领事“我们
要作甚麽事，才能解决方励之问题？”。大使立即将谢的举动转告我们。
我们判断:“这是邓小平发出的信号，中共想要解决问题了。” 大使也持同样看法。
谢希德的学术身份，是一位物理学教授，专长于点群空间群在固体物理中的应用。
谢的政治身份，是中共中央委员。谢是从美国回归者。八十年代，她每年至少到美国一
次，代表中国物理学会参加美国物理学会年会。谢认识李和我。早在1950年代后期，谢

对于ETD还是CID，在OT里做high resolution的MS2都更有利。而ETD是有利于high

MS2会让搜索效果更好。你搜索时记得把fragment ions的error window舍得很窄，这样
才起到high resolution的效果。比如10 or 20ppm，或者0.01 m/z，取决于你具体的
