Nikon官方有回了: http://forums.dpreview.com/forums/read.asp?forum=1021&message=28811881 "Thanks for the samples. It's normal to see some blooming from areas of extreme overexposure (the lamp) next to areas of general underexposure (the rest of the photo). This is especially normal at extreme ISO settings. Based on this sample I don't see anything wrong with your camera. Thanks" So people, this is NORMAL.
超高ISO下(約含6400以上,看大家的例子),極端的光源(街燈夜景etc)就有可能產生此現象...難怪我幫朋友拍昏暗的婚攝都沒看過...因為我都固定ISO or Auto ISO到3200而已.. 不過我記得D3在昏黃的嬰兒房ISO 6400也沒看過,不知是否跟JPG直出有關?小弟都只拍RAW...還是果然用料有差嗎? 不過對小弟D700夠用了...等D800錄影跟定焦群更新....
例如下面這張圖,都已經開到ISO-2800而且嚴重過曝到建築物都變成白色的,但是也沒見到明顯的橫條紋。拍攝當時是採High ISO NR - On (Normal), Long Exposure NR - Off, Active D-Lighting - On的設定,沒有後製,直接拿ViewNX直接縮小照片尺寸轉輸出為JPEG,因此應該不會有太多軟體設定差異造成的影響。
