Adjusting the colour temperature is easy with RAW files. It should be possible with JPEGs too. Any idea how to achieve the same thing? I'm not fussed if it's a long winded process, I'm interested in doing it all the same.

Open in an image editing program (photoshop etc), adjust colour, save. Only negative is loss each time you save, so if you want to keep original remember to do a "save as".

Edit, I just double checked, colour temperature is not specifically in Elements although other colour balance options are. I do know it is in Paint Shop Pro 7 (and I assume later versions too). So will depend on the program.

I was afraid I'd have to manually do it the hard way with curves. I guess that settles it then, I'm going to shoot in RAW.

In LR, under WB there are two sliders, which change 'Cold-Warm' and 'Green-Purple' Hue! Is that similar to what your talking about?

While I think that's a great idea, I think you should hold on a sec. JPEGs are as easy to manipulate in every aspect, you only lose out on quality. Whatever it is that you are using to adjust the colour temp of your RAW files should work with JPEGs too. It may be that some RAW converters chose not to allow this degree of fine tuning for JPEGs for whatever strange reason but it is possible.

My copy of ACR that comes with Photoshop Elements doesn't allow me to manipulate JPEGs. At least, I don't think that it does.

It should, if not it's a mostly useless program.

ACR = Adobe Camera RAW = for RAW files only. It not opening jpegs is perfectly within its scope. Elements itself does the jpeg part, and it does not appear to have a colour temperature adjustment, but does have other colour balance options.

ACR works with 16 bit TIFFs and PNGs. I'll go home and check whether it works with JPEGs. If not, I'll do my colour temperature adjustments manually with curves. It'll just take longer.

Nope, can't find any way of getting ACR to edit JPEGs. I'm going to go back to shooting RAW.

I see what he's saying now. I thought he meant that you can change color temp in Elements with a RAW file but not JPEG. I'm not familiar with elements, I've used normal photoshop since the beginning.

Yeah, Elements is a bit meh when it comes to features. I'm finding the lack of layer masks, no dodge/burn tool, and this colour temperature thing very annoying.

Then again, it is significantly lower cost than the full version... you get what you pay for. I don't find I need to adjust colour temperature directly, and other minor adjustments are adequate.

I thought that I'd revisit this thread. I've had a lot more practice with Elements since I posted this and have found a way to overcome most of the issues.

For adjusting the colour temperature, go to Enhance->Adjust Colour->Colour Variations. A scene that is too "cool" has too much blue in it, so remove some blue. To cool down a scene, just add blue.

Pretty simple especially since there's a live preview showing you the changes as you apply them.

Lightroom can easily tweak the colour temperature in Jpg's, I used to do this all the time ;)

Here's an example:
