Experimenting with a new slave strobe to the left in combination with a flash set up as a fill to the right at 1/64 power. Both triggered by on camera flash set on manual and fired at 1/16 power. B&W conversion using Channel Mixer. Film grain with gaussian blur overlaid via layers.
i like very much b/w tone you've made with channel mixer. it's a hard bw, with strong highlights and deep shadows. great work, it gives a particular character to this portrait.
