It stands for "Various photography" so for someone who likes to take all kinds of different photographies... if someone is looking for miscellaneous photography they will type in misc.photography in their browser to search but in reality it will take them directly to the future website with this domain name.
I have no problem that you regged a .photography name , it's just the term seems clumsy and perhaps hard to pass the radio test, sorry but i cant see any value at this point, good luck
