Working with jpeg in lightroom and cs3

I shoot raw because I like to adjust the WB when needed. Can I adjust the jpegs (WB) in lightroom and cs3 just like a raw image? If so I'd like to shoot in jpeg instead of raw. This would save time and hard drive space.

In Lightroom you can adjust the temperature slider but it does not give you absolute temperature values. When loading a jpg in to edit the temperate comes out as a value of 0. As far as I know you cannot adjust temperature from within Photoshop but you might be able to in ACR. I haven't tried that part.

There is so much more to shooting RAW than just being able to adjust the temperature. If you decide to shoot JPG over CR2's you will be losing alot of data that is just not there to edit once you load the image. No doubt it would accomplish your desire to save disk space. Disk space is so reasonably priced these days I personally would not find this good justification for doing this. The loss of data far outweighs the advantages that you might achieve here.

I've never shot in RAW.... BUT, when I edit my Jpeg's in CS3 I can adjust WB quite a bit..... Or anything else that needs help.

I Do plan on shooting in RAW soon but I just need to get the hang of the editing.

I attended the seminar in Houston with Pierce "Captivated by the light". He made it sound like jpegs could be adjusted like a raw file in lightroom and cs3. I was just hoping someone could clear that up for me. A person next to me in the seminar told me you can do the wb in lightroom and cs3 but not cs2.

You can adjust WB in most all phot editing programs in a Jpeg...... Maybe not as extensively as RAW but I do it all the time.
I used to use Paint Shop Pro 8 to edit my pics and it worked just the same as CS3.
I can't see where CS2 would be any different than CS3 in adjusting WB!?!?

I have found you can make minor WB adjustments in CS3. Open CS3 go to file>open as then browse for image. Use drop down and click on camera raw then choose image and it opens in ACR.

I guess part of the question is can you open .jpgs in ACR in CS2... its a pretty recent addition to be able to do this, I believe.

But in the end, you have more range in adjustments before unsightly artifacts creep in if adjusting a RAW vs. adjusting a .jpg. And this applies to more than just WB.

It just sounded like the lightroom and cs3 had something new that allowed for jpegs to be adjusted like a raw file. I'll take some pics tonight and run lightroom and cs3 and see what it can do.

Yes... LR and CS3 DO adjust .jpgs, no question.

But as far as original post asking if adjustments are "just like a raw image" the answer is 'sort of.'

Yes the same tools are available... none are disabled... but the quality of the adjustment, the highlight recovery, how far you can push as slider before image turns to much is different. Much more latitude in RAW.... its not a reason to switch from RAW to .jpg, if that's what you're asking.
