    I just made a stupid and classic error. Last time I used my D7000, I left it set for indoor light with the white balance set to Tungsten light. Last night I went out in a RIB and took maybe 330 shots of a series of yacht racing classes. About 60 yachts. Good light and good views as a lot were taken from an offshore platform. Now I have a problem as lots of sailors are looking forward to some pictures of their crews and boats racing! Of course the pics are horribly blue!

    I have PC copies of Photoshop and Bridge CS3 (old) , and Photoshop elements (new) and well as the camera itself.

    I want to find a quick and effective way to correct the problem. Any helpful suggestions (other than to remember to reset to defaults!)welcome.

    Assuming you shot raw this shouldbe able to be fixed if you open them in PSE.

    Start PSE > photo editor > file > open > choose RAW file

    This opens up a new window with the picture and various editing options - left hand side > white balance drop down menue > play around but daylight or shade may do it otherwise manually edit the colour temp slider. Then open image.

    I think you can possible do this in batch but not tried it out.

    The quickest way I've found of doing this is to use the "Neutral Colour Picker" in Picasa - worked for me when I made the same mistake as you did. Of course, "quick" is relative, as it will have to be done one shot at a time; fortunately I only had half-a-dozen to correct!

    Even if you have shot jpeg you can easily rebalance shots just by using additive RGB colour offsets, Make sure you maintain luminance though.

    Thanks to all so far

    Sods law applies as usual, RAW was OFF!

    Any guidance or advice on using "additive RGB colour offsets" welcome?

    I find that the typical "auto correct" or "smart fix" function in most imaging programmes often fixes this as it assumes you want to correct things to daylight.
    So it finds things it assumes should be white - typically the palest thing in the photo - and then changes the colour of the whole photo to fix that. So things with a warm tungsten cast are made cooler in the process.

    No harm in trying that first.

    Add operator is probably called brightness in something like photoshop. You can also use a multiplication operator ( mult/gain) . Photoshop is annoying because it calls operators by dumb names instead of just calling a spade a spade.

    Just adjust the RGB sliders until the image looks neutral , try and leave green alone and adjust red and blue as that will minimise the impact into the luminance.

    Also you could convert the colorspace after you have balanced to YUV or HSI and mix back the Y or I channel to restore the luminance balance within reason and depending on the matrix its used to calculate the colorspace conversion.

    If you are gong to use a mult type operator you may get a more predicatble result by linearising the jpeg first (hit it with a 0.4 gamma , color correct and monitor it back with a 1/0.4 gamma applied back to convert it back to video colorspace; do it by the numbers and it will be transparently reversible).

    Inflating to at least 16bit float (not sure if photoshop offers float in anything less than 32bit workflow) will ensure transparency.

    This would take me about 3 minutes , its an easy process.

    Thanks for all advice. I found the easiest and probably the best way was to correct a whole bunch of pics at the same time was download a free trial copy of Adobe's Lightroom 5.

    Imported all the jpgs direct from camera to pc on LR5 library module.

    Found a representative shot and used the develop module to correct the
    white balance from "as shot" to "custom". Selected a grey neutral area
    with the eyedropper and hey presto ! Fixed the problem on on that picture.

    Then multiselected a lot more pics and used "synchronise" to apply the same correcting setting to all of them. If important could colour temperature correct as needed per picture.

    A really nice features is that until you export the fixed-up jpgs to another area, LR5 just stores the original pics and the changes. So everything is reversible.

    Anybody got a full copy of Adobe Lightroom 5 for sale?
