Black and White conversions are creative by nature, so there are multiple ways to go about it. RAW Power has four different simple black and white conversion tools you can try:
1. The Black and White adjustment, which has various color filters.
2. The Fuji Acros Simulation
3. Other Black and White LUTs that come with the app
4. Presets – there are three BW conversions in there as well.
You can also download LUTs from elsewhere that have nice BW conversions.
