Fine Tweaking The HVL-F56AM in Manual Mode
Posted: Mon Jul 28, 2008 2:22 pm
I've been experiencing frustration with my 56. I use it in manual mode almost 100% of the time because TTL only results in giving me headaches with Sony A100 and A700. When I'm at the higher ISO 3200 (A-700) sometimes the power setting of 1/32 just isn't low enough.
Here is the situation.. the room light dictates ISO3200 at 1/30 of a second at F2.8.
I want to shoot 1 stop over ambient so I manually place my camera at ISO3200, 1/60 f2.8.
I could change any of the exposure variables to get under by one stop but I choose shutter speed.
Here is the problem.. my 56 am lots of time will be too hot at 1/32 power when I'm at this high of an ISO.. How can I lower the intensity of the flash:
1. Without having to back up further from my subject
2. When in a situation when I can't bounce and diffuse from a ceiling or wall.
I've noticed that in TTL mode with the compensation the flash is able to make fine grain power changes that seem to be the equivalent of 1/3 stop changes in light and TTL can shoot at a setting with less power than 1/32. How can I do this manually? I really don't like having to stop down because then that changes my ambient light. I want to keep my ambient 1 stop under and ONLY change the flash power.
Do you know of a flash that will allow me this type of really fine grained ability? And yes I know that I could put some kind of diffuser over my flash head to help control the lowest light intensity.
