colinbm Posted January 27, 2022 Share Posted January 27, 2022 Nice work Dave. Have you considered the use of a UVA converted flash for your UVA & UVIVF photos ? Link to comment
Andy Perrin Posted January 27, 2022 Share Posted January 27, 2022 Colin, it says that middle one was made with a Nissin Di866 Mark II flash. There is no benefit to a flash for UVIVF I don't think. Link to comment

DaveO Posted January 27, 2022 Author Share Posted January 27, 2022 I use the gear that I have put together with very few changes since I started, it does the job "If it ain't broke don't fix it". I tried without much success to do UVIVFL (in the bush) but gave up and decided to only take my UVIVFL photos in my converted darkroom. You will see where I only take Visible and UV pairs that they were taken in the bush. Link to comment
