White Balance for Jpegs?

Greeting all...
New to this forum...so hope I'm in the right location.

Was drawn to this site trying to resolve an issue with some 200 Plus Images taken in Jpeg with White Balance incorrectly set to Fluorescent while outdoors.

The Archives mention a Photo Retouch Member name Manta1900 who had a Beta Program for this fix. Downloaded the Beta version but do not seem to be able to find the full version...Can anyone point me in the right directon?

Thanks

Re: White Balance for Jpegs?

If you have CS3, the easiest way to fix is open your jpegs in Camera Raw and and set White Balance to Auto. It works pretty well. Otherwise, it's going to take a lot of color corrections, preferably with curves or in LAB color space. Why don't you post an image here and see what we can help you.

Re: White Balance for Jpegs?

Thanks Pixel Monkey.

Don't have CS, but am using PSE5 and Capture NX for post production and I'm fairly new at both of these, so Levels and Curves are currently beyond my comprehension. If someone would be gracious enough to do a basic retouch...basically as close to what would have been an Auto White Balance setting for this image it would be greatly appreciated. If the Retouch could be done in either PSE5 or Capture NX with some basic steps involved, I could then begin to tackle the additional 200 plus other photos with the same issue.

Here's a list of the Camera Settings for this image if they help.
Exposure Mode=Programmed Auto
Metering=Multi-Pattern
Shutter Speed=1/320 f5.6
Exposure Comp=0
Color Mode= Mode iiia (sRGB)
Tone Compensation=Auto
Saturation=Enhanced
White Balance=Fluorescent

Hi Princly,

I don't use elements, but surely it has a levels adjustment feature This is basically what I did to this image.

Duplicate layer - Use Levels adjustment on the individual channels bringing the sliders to the majority of the information. Use shadow/highlight filter and adjust accordingly. Use selective colour adjustment layer.

It isn't the best that can be done, but lovely hot pizza awaits me ...... yum

Re: White Balance for Jpegs?

You may not be able to levels adjust individual colour channels in Elements, older versions did not have this facility (the main reason I upgraded to PS all those years ago).

The Auto Levels tool which comes with Elements does a pretty good job of colour balancing your pic.

Some of the whites in the clouds seem a little blown out after using it, but you can adjust that by doing a manual levels adjustment afterwards.

Open levels and bring the right hand slider on the output (bottom) bar in a little from the end, until the blown out sky areas are as you'd like them to look.

I did all the adjustments on your pic using Elements 2 (I have an old copy), so these tools should be available on Elements 5.

Hi Princly,

I had pizza with the lot, and I'm sitting here thinking .... god, I shouldn't have eaten all that

The great thing about adjustment layers, is that you can drag them onto other photos. The only thing that you will have to do manually is the shadow/highlighting ... assuming elements has that feature.

With PSE5 you have 2 automatic adjustments which should get you close with one click : Auto color correction (Maj Ctrl B) or auto levels (Maj Ctrl L). Better use color adjustment for color cast correction (first option) and click with the eye dropper on a neutral gray spot.
For those using ACR 4.1 with PSE5, the auto color balance works like in CS3 or Lightroom and does the best job.

Re: White Balance for Jpegs?

It's really hard to tell what were the colors of the original scene. Here's a rendition based upon tuning the highlights to pure white. Is this close to reality?

Re: White Balance for Jpegs?

Following pixel_monkey’s advice I opened the jpeg in a raw mode & did some adjustments there (no auto mode, it didn’t work well with this image).
Next, I did curve adjustments in lab channels & some level correction on the clouds.
