I am using D90, but don't know why the picture is usually a bit yellow when the picture is taken indoor (around 8:00 p.m. I took several picture at normal under normal lighting at home, but it is yellow even I use flash. When I adjust the WB, it is improved, but the colour is not natural, how can I improve it)

用閃光燈, set 去 awb 就得
如果set 左高的iso, 因為會吸多左背景光, 所以有時會黃d
(用flash, 閃光燈係控制主體光量, iso/ 快門就係控制背景光)

你用左咩mode ?
試下用閃光燈時機身用 m mode, 自己set 光圈, 快門就 1/30 至 1/200之間
(iso 就唔駛好高, 一般 200-800 都夠)

回覆 2# chloepapa 的文章

Firstly, I used auto mode with flash on and auto w/b, but very yellow.
Secondly, I tried A mode, with flash on, 1/60, and auto w/b. This time, better than auto mode. But still has some yellow.

Is it very difficult to take picture with dim lighting as those at home.

試下SET ISO 去100, 200
(用高ISO, 會吸多左現場光, 係會黃D)

照你講會係white balance 錯左, 唔知你屋企環境點, 試下影白色set manual white balance?

I tried to use 200, it is better and is very close to my expectation and it is same as the old camera of Minolta using negative film.

I think it also solve my previous problem of taking yellow photo in hotel room.

I have bought D90 for half year and each time, the picture is not as good as I think or compared to my old camera (about 10 years when I son is borne), so I am very upset and always think whether there is something wrong about my D90 (also my skill is also at the stage of new learner).

I have tried many picture at home today. When I use auto mode, the picture is still yellow. But when I use P mode, auto w/b and set the ISO200, flash, 1/60, it is much better.

Then I tried to compare picture taken with auto mode and those setting as said above under P mode. The output is very different. For those taken under auto mode, ISO is usually high upto 800 or 640, but still yellow. On the other hand, when I use P mode, the problem of yellow is miniminal.

So I think my problem is that the ISO is too high and absorb too much yellow light from the indoor environment.

Thanks for those giving advices and give me a clue to try and solve my problem.

室內低ISO我驚你手震, 我用過D90, ISO 1600 都好掂. 樓主下次可以試下A mode, auto ISO, AWB 影raw. WB唔岩就係view NX 改, 煩小幾樣架~

The solution of yellowish is

1) use pre-set white balance

2) take RAW and adjust white balance when you edit photos

iso may affect (I don't know), but not as key as white balance.

一張好的作品,畫面要簡潔有力。所以有人說攝影是減法畫畫是加法的意思就在這。

一張好的作品,需要有好的內容,好的構思、好的規劃,最重要的是觀察力、有人文藝術涵養以及感性知性的心。當然,相機隨身帶著。

I tried to attach two pictures for comparision. The first on is on Auto mode, 1/60, f4.8 and iso800

The 2nd one is on P mode, 1/30, f4.8 iso200.

The 1st one with my usual problem on auto mode with yellow background

The 2nd one is that I usually taken with my old camera.

最好將d 相upload 去d 網站,
出post 時click 輸入文字框左上角的 "插入圖片" icon, copy and paste 張已upload 相片的link 上去就ok
