M8 single frame

50 secs @ ISO 3200.Due to the weather I am reduced to playing with my old stuff.
Just noticed the sort of cross hatching; I think it was caused during the downsizing process.

A lot there for a single frame.

Yeah processing artifacts are always a problem I battle. Bringing out the faint stuff also means increasing the noise, gradients and other undesirables. Then learning how to cope with them.
