Editing JPEGs - is there hope?

[Jacinta B]

Hi Damien. I just did my BEST work EVER. Except my daughter forgot to pop the white balance sheet in the car, so imagine my surprise when I got home and popped all those amazing images onto the hard drives and lovingly poured over them in Bridge and discovered I couldn't open them directly into ACR to get the WB all good. Perplexed, I googled, searched your site and checked the METADATA and to my HORROR discovered that the entire session has been shot and backed up in JPEG  

So, I have no idea where to from here. THANK god the photos are well focussed and I even worked some magic with off camera flash so the ISO didn't bust my chops like usual. Theres over an hours worth of images all capturing different light as the sun was setting. I am too scared to edit them at all- they don't really need cropping, so thats a plus. But please can you help me steer this Titanic away from the 'berg? 

The images are all 3680x 5520 and all around 10MB each. ALL 400 of them   

An image from the session to share my heartbreak

Thank you....

With jpeg files you can't fix blowouts.  So if you shot any where the sky is blown out, there's nothing you can do about that.

Otherwise, you can edit them just fine, don't worry.
