I am having difficulty distinguishing between bud drop, sooty mold or the possibility of just poor placement of my camellia. Is it possible to have all three? I would like to send a picture of the plant if I may? I am seriously considering digging it up and relocating to a more shaded area possibly while letting it rest it in a container of peat moss to see if that helps as well. I do not think I have overwatered it but we have had quite a bit of spring rain. Also, it got hot very quickly then temps dropped again. I live in Charleston, SC.

I don't see any Sooty Mold on the plant.
Here is a link about Sooty Mold and how to identify it.
Your Camellia should be planted in 'dappled sunshine', I think your plant is receiving too much sunlight.
Check the watering and drainage also.
Is this a new planting? Water newly planted shrubs more frequently, but properly draining soil will help with excess moisture.
Fertilizing is important for healthy Camellias.
Here are some links to help refresh you on the care requirements.
