试验HDR
公历七月初的今天，七点不到，从东墙窗洞射进来的阳光就让人眼睛有点儿刺。
与泻在盥洗室光洁的地板上的“高光”相比较，其它的非直射光的地方就显得非常的暗。
如今数码相机虽然成了摄影工具的绝对主流，但数码相机的对比度（或者说光线最亮到最暗的包容范围）仍然比胶片相机狭小不少。
因此，象今天盥洗室这样的大对比度，一般认为想拍摄好是点难度的。
所以，这种情况下，一般推荐用HDR拍摄。
想起A55相机上有HDR功能，就试试吧。

我这里不可能做严格的质量测试，只用直方图所包容的范围和图片直观质量感觉来粗浅地比较。
除了4种HDR状态（ AUTO HDR和水平设置1、3、5），我还用AUTO档试了几张。
结果发现，HDR状态一般比较稳妥。
而在今天的情况下，一般非HDR也可能拍摄到包容范围比较满意的照片。
（毕竟不是中午在阳光曝晒下的室外，虽然眼睛感觉对比度很大，实际还可以。）
这里是用非HDR拍摄的照片。作为数码相机对光线最亮到最暗的包容范围的估计。
（请勿误解，不是指照片的技术水平、更不是指照片的艺术水平比较满意。）

This special annual tradition at St. Benedict School will bring together members of the Amherst community, parishioners, school families and others looking to win that special grand prize of $10,000.

The lady (rather rude, from dealing with angered callers such as myself all week) informed me that I did not purchase a pair of sunglasses, but a SUBSCRIPTION to 2 pairs every month. I said NO, I did not do this, it said nowhere on the site about it. She said it does say on the site.
