there is a hope.. if you had just crossed the line while taking a U turn, then go to police station and request to review the photo shot... and if Captain feels your claim to be genuine he has the authority to reduce your fine..
I know this becoz friend of mine barely crossed the line when light turned red, so after some months when he requested to review the photo instead of original 6000 he was asked to pay 1000... so there is a hope. so check the pics and if you are lucky you can get away with the lowest possible.. all the best..
