Getting White Balance Right?

Maybe not so much a retouching thread - but a critical issue in post production work.

I shoot RAW and come processing time there are some images that I find very difficult to attain the right white balance. In this instance I started by clicking an area of the dress - but its still not quite right.

Any secrets from you all as to getting it right.

Re: Getting White Balance Right?

This is how I do it.

This get the white balance in the right ball park (and sometimes it's right on) but I usually fine tune it from here. Also, before you leave the Level dialog box, click on the Options button. There are three different algorithms you can select from. Sometimes the results are the same and sometimes different. There is also a Snap Neutral Midtones box you can check.

I also set the Output Level to Blackpoint=5 and Whitepoint=245. From here it's usually on the Hue/Saturation

Re: Getting White Balance Right?

Do a custom white balance with a "gray card" before you shoot if you wanna eliminate the whole process of color correction at post production. It'll take care of literally all unrealistic casts, especially on wedding dresses.

I used the Threshold layer technique with some fine tuning for your image.

Global Color Adjustments

Well you probably already know this, but using Image/Adjustment/Variations can give you a clue on which way to go. From what that showed me it appears that adding a little red could be helpful.

It also appears that the background is influencing her skin color some and green may not be the best background color to work with.

I switched to lab and boosted the magenta a tad

Re: Getting White Balance Right?

This is a quick mode...
open the image on PS, then on Curves adjustment select Options, that opens another window, there you must select on Algorithms, Enhance per Channel Contrast and on the Target Colors & Clipping click on the black color, in the next window on the RGB values put R 5 - G 5 - B 5 and click OK, click on the white color and put this values R 250 - G 250 - B 250 and click OK, click OK again and you're back on Curves there now you can make the image a bit brighter moving the curve to the white and click OK. The black and white adjustments that you made on Curves helps you to neutralize RGB images.

You'll have a result like this...

Hope this helps.
Silvia.

Re: Getting White Balance Right?

I think the white off the dress is fine the problem is that the left side of here face it bleached with white light and the right side is deep in a shadow making the freckles look like sploches....so what I did was mellow skin on right side..then added a lighten curve with a gradient mask leaving the bottom the same shade and increase the llight from the neck up.

I think it looks better..

Re: Getting White Balance Right?

The problem here is that there is no true white in the picture to begin with. The best thing to do on here is the skin, hair, and the pearls. She leans toward being a redhead, with freckles. The dress is not white, but some shade of ivory to match the pearls, which also are not white, but on the yellow side.

Setting the dress to white plays havoc with her face and her chest tones. This is a rough try. I may err a little on the colorful side, but that would be child's play to pull back. Setting the dress to white, however, has the effect of killing alot of critical highlights.

Re: Getting White Balance Right?

Duffy has a point...Jasosmith, is that the original image or have you already worked it in some way..(white point.. curves.. or hue/sat?)
If not original it would probably help to have the people here try and help off the original..

Re: Getting White Balance Right?

Don't agree with Duffy and Lasa, I took the original and Duffy's version and made a quick adjustment to both of them, here are the results...

By the way as a photographer and graphic designer I think that the jasosmith image is the original without any work.
