This set contains 16 Photoshop actions to convert color photographs into Black and White. I managed to include High key (highlights dominant), Low key (shadows dominant) and everything in between. All 16 conversions will be rendered from once and your task is to choose one you like most or even to further enhance conversion since everything will be done using Adjustment layers, Smart Object layers and Smart filters.
You can use actions with Photoshop CS3 and later version. For Photoshop CS6/CC users there is conditional action which will detect if your document is layered or not, otherwise run Play all / Bgr layer only or Play all / layered file action.
