Why would I need TTL for an off camera flash?

post #1 of 8
Thread Starter 
Looking at a set of Yongnuo RF 603N because they're pretty cheap. They don't support TTL signals. Now, I'm mostly shooting manual and plan to use the flash off camera mostly. Why would I need TTL support?
As for Equipment the thing will bridge my D7000 to a SB700 (which I'm about to buy)

i wouldnt worry. its more rewarding to learn flash in general via manual exposure. more of a challenge and the most fun part is when you are ready to make the move from 1 off camera flash to 2 flashes to 3 to 4 etc... biggrin.gif

You don't specifically need it, it's just a handy feature that could help you depending on the situation. Personally I wouldn't worry about it either due to it be generally inconsistent, and personally because I only use a strobe 10% of the time.

Always something nice to have on-board but the benefits don't outweigh the price differences in trigger systems.

I kind of thought so. It already felt pretty darn much rewarding to finally be able to shoot manual in general.
Is it really that inconsistent? The whole manual thing feels pretty great due to the exact control over what you get.

I'm not sure if I'd want to plaster the woods with more than one flash for some shooting but you never know biggrin.gif Ah first, lets get the grip on this one before I add yet more variables.

On a whole it's not inconsistent a ridiculous amount of the time (in fact it exposes the shots quite well for being automatic) but you can run into it if say you use it for the same type of shot multiple times. You can see variances in flash power if you compare those frames side by side.

It's not off by a terrible margin a lot of the time but when you're editing you'll start to see it creep up on you. Maybe it'll start irking you depending on how important your work and time is to you if you do in fact use it but it sounds like you're going down the right path currently.

Generally speaking:

Moving subject [flash to subject NOT camera to subject] = TTL
Static subject [ditto] = Manual

YMMV

Well, taking the whole moving subject part into account I'll be having a little bit of everything. Overall my plan would be to stay in manual but so far I have very little experience with the whole flash thing except for a lengthy flash tutorial from FroKnowsPhoto. The whole thing looked prettty straightforward but they had a studio and a beauty on a stool whereas I mostly have downhill riders out in the woods. At least that tutorial also managed to get me out of auto so if it is any good for flash as well it was worth the price two times. biggrin.gif
My camera can be a flash commander with optical slaves so that'd leave some time for tinkering before getting some radio triggers. Maybe the optical slave thing works out in the wild but that remains to be tested. This weekend I wanted to give it a shot but ended up riding till dawn instead of grabbing the camera thumb.gif

d7000 and sb700 can be shot in wireless mode with no extra accessories - set the d7000 into commander and set the sb700 into slave.
