I don't know if im missing something but I cant seem to get flash expourse compensation to work. Im using a Nikon d7100 and a Nissin di622 mark ii. It has expoure compensation on the back ranging from -1.5 to +1.5 but when I change it I can't see any difference. I'm a complete flash noob and have only used it on the hotshoe in ttl mode so far. The way I understand it in very simple terms, you set your camera for ambient light for background then can set flash expoure compensation for the subject exposure, is that about right? Thanks for any help
 
With Nikon you need to adjust both EC and FEC as far as I can work out from the Hotshoe diaries. They should balance.

I find it overly complex, with Canon they are completely independent (as the exposures are).
 
Thanks Phil, that book was next on my list. I bought Speedlighters Handbook first (although its for Canon speedlights) as my initial thoughts were I thought the Hotshoe Diaries could get quite annoying due to writting style. I seem to be taking one step forward and 4 back at the minute....These flashguns aren't as easy to use as they look :) I seem to be having more success manually but it means diving into the menu more.
 
My general rule is to use TTL for when I'm moving around lots or the scene is changing constantly, but to use Manual in any sort of studio or static set up.

That's the easiest thing both ways round.

Hi Phil V. How you finding Hotshoe Diaries?

I wasn't sure about his writing style at first, but once I got over it I found it a good read. Easy to pick up for half an hour or so, which made for good reading on the train.

It's Light Science and Magic next.
 
"How" are you using the flash and the camera (modes)?
Usually it gets "confusing" when using TTL and some kind of semi auto mode. With most Nikons (all by default) FEC affects only the flash and Camera EC affects both the flash and the ambient. So you set your lighting ratio using FEC and then move the entire exposure up/down with CEC.

When using the speedlight for fill (or bounced) set below ambient, small changes in FEC (1 stop or less) will not usually be terribly obvious.

Edit: I saw the flash is in TTL.

Thanks Steven, I was trying with ttl on AP but I've been getting much more success with ttl on Manual mode

I have no idea with Nikon, but the semi auto modes with flash on the Canon drive me insane. I always switch to M when flash is the main source of light, using ETTL or Manual to control the flash.

Nikon can be the same, at least for me. I think a lot of it is due to metering...

Been reading this. One of THE best books I've come across. What I like about this books is that it concentrates on the principals of how light works and not overly on any one genre of photography. Understand light and you'll be apply this knowledge to any type of photography.
