color temp-white ballance is a key thing that messes up your colors, when you get it "from the camera" without make-up. This is a difference how your sencor and your eye read the reality - you set up gray color by your self, but you have to tell your camera which color is which, because with different light - the colors look differently. color temperature - is a temperature of Iridium radiator that coresponds with given luminosity, less temperature - more it red, more temp - blue. I think it is one of the key portion of photography with digital camera. the link is to the excellent article about it:http://www.nikondigital.org/articles/white_balance.htm
The message is - if you set on authomatic - you can not get 2 images from the same scenary with the same colors if you shoot in changed light situation. The white balance filter is expencive, and not needed for our purposes, white balance cap - could be substituted by a piece of a milk bottle pressed against the lense - you will see the picture - and can do a necessary correction, that could be the same at any time. It can spare some aggravation later. Personally I prefare to shoot with low color balance and recover colors lately. | | | [1] | | | October 31st, 2006 05:13 PM | | LVE

Very interesting. I have a couple of questions. If you know, when I shoot in Raw Mode, the color temperature settings become infinite. For example if I shoot in Raw + JPG where I get a jpg file and a raw file, it appears to me that working with the color temperature is really the whole deal. If I adjust color temperature, and tweek a few other things in the Raw Editor, save as a tiff, and then work some more in PS, it is my opininion that this cannot be duplicated using the jpg from the camera and editing normally. Am I correct, or is this my imagination? To my eye it is a world of difference! | | October 31st, 2006 05:25 PM | | andreyG

Actually you are right, by definition - you can place the point of white balance anywhere in a raw mode, changing the balance in raw you just tell to the screen which one is white, and it adjust all of them, colors. In JPG them, colors are already fixed, and when you change white balance you change the existing them, who? - sure colors. I sorta like this effect when I shoot with low color temperature and get redddish original - the colors that I recover are more vibrant, but less natural. I do not care too much about mother nature, I care about my pictures - and it is OK with me. But RAW gives you much more flexibility with white balance. | | November 2nd, 2006 01:12 PM | | LVE

I am still finding my way around my new camera. Onit I have a setting that lets me set the temperature I want to shoot at. I played with it this morning, in both raw and jpg, but have processed it yet. I will let you know. I hope I can see it in my exif data because I didn't write it down! | | June 14th, 2010 10:56 AM | | JrPhotog

I know this is an older post and I am sure you have all moved ahead.
The best the way to set your color temperature, aka (Kelvin temperature.)
Color is then measured in degrees kelvin. As 3200 degrees represents a warm room light. Tungsten. 5200-5700 would be noon daylight. Then there is other factors such as reflecting light as off trees or a red brick building. Just enough to drive you a little crazy and off your mark for the details of the subject you are shooting.
The one true and final fix would be to purchase a kelvin temp meter. Along with reading the measurements for exposure, you get the exact color temp setting. | | | [1] | |
