Once I did get CyanogenMod, the built in camera app doesn't have the slow motion camera feature anymore, and I don't know how to get it back.
Is there possibly a Galaxy S4 stock camera?
The stock camera app is limited to Touchwiz, so you can't use it on CyanogenMod, however if you install a TW based ROM you will have it again! I recommended using the dual boot mod and then installing both ROMs, I had Phoenix and CM11 (GT-i9505).
