Why WB tends to be off on the yellower side?? Xplorer Gold Star Critiquer/Silver Workshop Editor/Gold Note Writer [C: 125 W: 13 N: 327] (2187)::2012-04-05 0:28
I know its a oft repeated and discussed topic these days on TN and I am not immune to it. In fact it is quite apparent from the number of workshops on the subject that it is significantly important and can make or mar an image. What puzzles me though is why the WB always tend to err mostly on one side. That is in most cases the images have a yellow cast. One reason must be direct sunlight. The other which I have noticed is the use of contrast during PP that tends to accentuate the bright colors at the cost of the cold ones. There are not many images which look colder than they actually should be. Point to ponder further..

Do you mean that the actual photos in general have a more warmer white balance result? Or, do you mean that because the workshops in TN are mostly focused on a (very)cool white balance preference? Workshops on TN don't automatically make it correct, it is just a personal interpretation/preference of that member. What counts is the actual lighting situation at the moment the photo was made (only to be determined by the photographer and anybody else present, the monitor setting of the viewer/photographer, and the personal preference of the viewer/photographer. In addition, which 'white balance' do you follow, that of the human eye or of the camera?

Let me go for your last Q first. The camera cannot come close to the performance level of the eye and hence the scope of adjustment in the WB is made available in the first place. I also agree that the photographer/viewer is best placed to decide that. And the workshops here are just personal interpretations. And I am not saying that images here in general have warmer white balance. But in my observation a lot of those images that seem to have WB issues mostly tend to be warmer. Now is that due to certain bias or is there any specific underlying technical reason is what I was interested in and how it could be addressed optimally.

Did you know that the cones in your eye will become saturated or tired rather quickly and adjust the receiving light temperature to an average temperature? A camera will not have this issue and can therefore register the actual temperature. It is the choise of the photographer to choose which he/she prefers to follow.

hello Himanshu,
I think that your observation is absolutely reasonable. In my practice here most of the workshop I have prepared, affect this matter more often. It maybe a question of personal taste, but the truth is that if I prefer my images to look warmer or colder this wont make them represent the reality of the scene correctly. The Automatic White Balance of most cameras including those which cost a bit less that a small jets, are still struggling to achieve the perfect white balance. So, ..take your images in RAW, then later adjust in PP.Simple as that, but generally when a white parts ( if any ) of the image has some cast, that means we have incorrect white balance settings. Please have a look the following examples here, where this issue is more obvious:

I think that in PP most people tend to warm rather than cool their images, but I find it very rare for the auto WB on my Nikon D300 to produce a "cool" result (specifically, only really noticeable in snow and clear skies). However, I also do a lot of my photography in the last few hours of the day when the sun is at a low angle (the "secret" for getting side-lighting for birds in flight)and there are genuine, natural warm sunset tones that can be very evident in the resulting photographs. It is tempting to "cool" these images too much in PP, but that may itself diverge from the "reality" of the original scene. Sometimes it is worth evaluating a scene with your own eyes and making a note of the lighting conditions.

Tastes and even actual colour perception are very personal in any case - I see green tones differently in my left and right eyes!

Oh, and the "cloudy skies" WB settings are always completely OTT on image warming and best avoided in my opinion!

Or, when a white part in a photo has a cast, it is reflecting the available light. (warm during the golden hours, cool during the blue hours) Without having a complete picture of the lighting situation at hand (e.g. you either needed to be there or the photographer must have provided full detail), any decision made on the white balance is a guess, a feeling, a preference, an interpretation of the viewer, etc, but

Don't get me wrong, I do agree with some of the workshop made, but also disagree with many others.

I agree completely, I almost always shoot early morning when the the light is just more golden. If at that time I shoot a swan or a spoonbill or a white orchid, its white is transformed to golden. I've had some workshops correcting this on my pictures, but in all honesty, I get out to get this shift in light color!

cheers

This is a fairly old thread, but hopefully the OP will see this.

Are you sure that your monitor is accurate? If your monitor isn't calibrated, you can't assume that what you're seeing on it is how the image actually looks.
