I've been using Rodinol at 1/50 dilution to develop FP4 film and to be honest could do with a bit more contrast in my negatives. My stock of film and Rodinol is just about finished so i need to replace soon - not sure what to go with to give me more contrast any ideas? oh BTW I'm shooting with a Bronny SQAi and a 1950s Zeiss Ikon Nettar and in 35mm land a Nikon F4.

Thanks

Chris
