White balance setting in M-P 240

[thjk]

I just notice that during I took some shots indoor i.e. in my living room, the colour of the pictures are difference even though they have the same exposure. For example, I took 2 shots with f1.4, 1/250 sec at ISO 1600 but the colour of these two pictures are different. The wall on one picture is light yellow (almost white) but the other one is brown shade. I think it is not because of the lens. I also try both of my Leica 35 lux FLE and Zeiss 50 Plannar but the pictures from both lens come out the same (same setting but different colour). However, I cannot notice any difference when I took pictures outdoor.

My camera setting is Auto ISO (maximum ISO at 3200) Max exposure time = 1/250 sec, Auto WB, Centre-weighted metering.

Is this normal? Or anything wrong with WB of my camera (M-P 240)

Different framing, different exposure, different colour distribution. Especially in uneven conditions like indoors.
If you want consistent results, you need to take the camera off auto. No AE, no AutoIso, no AWB.

Thanks for your reply.

Different colour distribution? Even though I use the same framing, composition and focus at the same point for those 2 pictures?

Yes, unless you use a tripod, images will be shifted slightly. That can be just enough to shift the AE and/or AWB.

Dear Jaap, Thanks again for your clarification.

In general, indoors I always use the "greycard" white balance. (carry a small grey/white card somewhere, or use a sheet of white paper, I use the Colorchecker Passport).That will give a neutral, cool result which can easily be shifted to warmer in postprocessing. That is much easier than trying to get rid of the yellow cast that AWB or Tungsten produce.
The same for midday sun in the tropics.

i keep the credit card size in my wallet and next larger size in my camera bag:

I checked in Amazon. The grey card is the same as white balance?

Probably not the situation in this case, but some indoor light sources change color temperature during the power cycle. I shoot regularly in one location where the change is very dramatic, to the degree that I can get a significance change between the top and bottom half of the image.

Not quite, but it will serve.
