This is the picture of the sky taken with D30 but it appears to be yellowish. The camera was set to AWB.



I adjusted the picture below with Photoshop to make it look more closer to the original color of the sky and cloud



Is there any calibration needed for my D30 Auto White Balance setting?

I forgot to mention that the picture was taken with Hoya Circular Polarizer. Could this be the cause?

I don't think there's anything necessarily wrong with your white balance. The shot seems perhaps a little under-exposed. Did you compensate a little for the white clouds (+1 stop maybe?) If you take that image and manually adjust the levels in Photoshop, it looks quite normal, and closer to your second picture.

It was set to Av without any compensation.
 
I second the results of boarderphreak. The exposure is wrong. Underexposed by about a stop. A simple Photoshop levels adjustment fixes it perfectly. When photograping a very bright subject add one stop of compensation and it would be perfect.

Please get or make a gray card and test if it will work for you. If it doesn't work get back to me tell me so. The polerizer is not the problem. Trust me and begin to love that camera. Adjusting WB in any program is so unnessesary.
This is a very strong feature on the D-30. The factory WB sucks!--Ron Warren

Try shooting that again with exposure compensation set to +1 or so. Your ideal solution would be to read a grey card outside for your base exposure and then bracket three exposures of the sky, but that's overkill and not too portable. Play with the exposure compensation - shoot once at +.5, once at +1 and again at +1.5.

The problem is that the camera is reading that white and adjusting the exposure down. A trick I often use is to take a meter reading that includes more blue sky and less clouds and lock that exposure, re-compose and shoot. That usually gets pretty close if not right on after a little practice.

The auto white-balance is like auto-anything...it takes it's best shot at guessing what the situation is. Looks like the expanse of blue sky which is probably at a very high color temperature is clashing with the lower temperature of the clouds which may be reflecting more sunlight than skylight. If you want to use the auto mode then be prepared to do a bit of fixin' now and then. You did it well.

Yes, the process of using a neutral target like a grey card to establish a baseline for a series of images will do the job for you.

White balance is a major part of digital photography. Canon wisely included the custom settings that allow user adjustments. Shoot raw and practice adjusting the 'click balance' in the conversion application.

One more thing, my friend...don't title your post with a blanket statement that the D30's white balance is out of whack. The camera has been around over a year now and quite a few folks on this forum know it's ins & outs fairly well including the white-balance techniques. There's nothing less than accurate about them. You have a legitimate question about YOUR use of YOUR camera's settings and that's fine. But you will be skipped over if you start off on the wrong foot and you will miss out on the help of a lot of knowledge.

Keep truckin'

Look into the Expo Disc, the best way to set custom white balance. Do a search here in this forum and read about it.
