Fix camera filters after nougat update?

[nlosch]

I've only had my phone running for a day with the latest update, but the grayscale camera filter seems to be MIA and the low light resolution is sub par now. I always found the grayscale filter to give better photos in low light, so even though I can edit a color photo to make it grey...it's not at all the same. I don't see grayscale as an option for a filter to download, but has anyone else run into this and found a solution?
