Syncing flash a little faster? |
so right now i'm using my dad's D80 for all my photography, and i plan on getting a flash this summer, but right now my built in one works pretty well, except i want it to sync faster. the fastest sync speed right now is 1/200, but i heard you can bump it up to 1/500. how would you go by doing this? i am doing skateboard shots, and a few things come out out kind of soft with 1/200 You are shooting on the Nikon D80, no matter which flash (even SB-800) you choose you will only be able to sync at 1/200. If you put the flash on the manual setting (SB series) and then set the flash to 1/4 power or lower you will be able to stop action better than if you were shooting at full power since the flash duration would be quicker. You may have to open up to allow a little bit more maybe 1-2 stops but this should help you. Here is an article that might help explain things even more and using the flashes TTL metering which has it's drawbacks. http://www.naturephotographers.net/artic... Hope this helps, Kevin Source(s): Professional Photographer The maximum shutter speed of the flash sync of a camera is fixed and is a result of the physical design of the shutter. That said, the flash unit itself, flashes at sometimes as short a time as !/50,000th of a second. This means if you underexpose the ambient lighting by about two or three stops and let the flash supply most of the light during the exposure. How to do this: With your shutter set at the maximum shutter sync setting, take a series of shots, each time closing the f/stop down a third of a stop until you get just the shot you want. Write it down and use that setting, in similar light for the next time you want to freeze frame your friends skateboarding. Editorial, sports and glamour photographer You're looking for "high speed sync". Some flashes (good quality ones) are capable of this. For example, I own a Canon 5D and a Canon speedlight 550EX. I can set the flash to high speed sync mode, and I can take shots at any speed. The camera allows me to take shots in as little as 1/8000 of a second. Here's what happens: Normally you can only sync in 1/200 second because the camera has to have the entire curtain open when the flash happens. The flash duration is super short, along the lines of 1/1000 - 1/10000 of a second. If the curtain is partially closed when it flashes, it will block part of the flash, then continue to open, and only receive ambient light. Now, high speed sync will actually increase the duration of the flash, and the intensity will be reduced for any given instant in time. Think of it this way, on a light bulb with a dimmer, you could flash it on super bright for a split second, or you could turn it on halfway for a longer period of time. Overall, you receive the same amount of light. So your flash bulb actually stays on for a longer time, perhaps 1/500 of a second, at a dimmer brightness. Now you can take your shot at a faster rate. I believe this chews batteries faster on the flash, and total output is reduced. No big deal though, this is a GREAT feature! If your flash doesn't have high speed sync, consider buying one that does. nikonfotos 100 knows what he speaks of. the d80 was designed with a max synch speed of 1/200. Why they did that I don't know because the d70 is 1/500 and I love it. So, your only other option is like he says, using a flash that you can cut the flash bursts speeds down. I use a old tried and true Vivitar 283 with a special module that allows me to set the flash burst speed down to 1/8 of full power if I need to. Good luck. |
