I've thought about adding some LED's under the stock hood, but I don't know that it is worth the time and expense. I will probably upgrade the entire light or maybe just deal with this one for now and learn from it, and then later move to a nicer tank and use this one for growing plants using the DSM.
And yes, it is very hard to take good pics. I've struggled with that. To keep my main stone from blowing out, I have to take the exposure compensation way down, and then I lose detail in the shadow.
