I recently purchssed a Olympus OM-D 5 Mark II camera. When taking SWUV photos, everything looks fine. With LWUV however, purple overpowers the photo and the fluoresence cannot be seen. I am unsing a Way-To-Cool lamp to illuminate the specimen. My guess is this is visible purple light from the UV lamp which is overpowering the fluoresence. I did not have this problem with my older Canon camera.
Does anyone have experience with this problem and know of a solution? Is there a filter to attach to overcome this problem?
