Can you tell me what is wrong with my camelia bushes? I've sent pics to show you how they look because its too hard to describe. I've done everything to the letter that is suggested by several books, web sites etc..for pests and diseases(ex:aphids, thrips, sooty mold...). I clean up debris and also thinned bushes and got rid of infected leaves. Nothing helps. what's eating my camelias? Help!

This is a fungal infections. Fortunately the answer is a simple one. Wettable sulfur and dolomitic lime will cure this right up. The sulfur will cure the disease while the dolomitic lime will help buffer the pH, so that it does not swing too low because of the sulfur.
Now the cause of this. This can usually be caused by overly wet soil. If this is out of your control, then your only method will be treating as it occurs.
It does not appear to be Mottle Leaf Virus, but if you do notice that the treatment isn't working than this could be the unfortunate case. There is not treatment for this disease, and Camellias can never be planted in this spot. I really don't think this is the case, but be on the lookout for bright yellow spots that will quickly take over.
