Need help setting up flash units

[john isaacs]

IIRC Godox TT350 is optically controlled off camera only, hence should be on slave and Auto mode, not TTL supported.

Not sure about the 6XX model.

IIRC you might need a Godox Remote Trigger (a TX?) instead of using TT350 as the master.

Does "optical" imply it has to be in the line of sight?

My intent was to use the built in radio trigger mechanism (whatever it's called).

I did get them to work the way I wanted. My preference is to use the smaller flash on camera (obvious size advantage) most of the time, and the two larger ones on the stands when needed.

Thanks.

alcelc has not remembered correctly. The TT350, like your larger TT685ii, has built in radio that can either transmit (TX) or receive (RX). I have both units in Flashpoint/Nikon flavor. Either one can be in the hot-shoe and the other off-camera. I bought the TT350 specifically to have a small on-camera fill light while triggering larger off-camera lights.

Both your light have the "S1" and "S2" optical remote modes which is what alcelc is remembering.

FYI optical triggering can work without line of sight in moderate-sized rooms provided you have reflective walls/ceiling to disperse the light from the on-camera flash. Line of sight is better of course and required outside, but if the ambient is high your range may be limited.

Agreed you should use the radio triggering, but if you are like me the issue becomes "how do I make the radio magic work".

I find it difficult to get my units configured the way I want especially if I haven't used them recently. Changing settings isn't always intuitive given that each Godox model has its own somewhat unique interface. Selecting between many options using just a few buttons and a dial requires a cryptic sequence of long and short pushes with careful attention to small icons on the display. Doing this from memory is likely to fail requiring a painful search in the users manual. I keep telling myself I should finish writing my own better instructions and transfer them to some index cards to keep in my bag.

That's what I am learning. Unless we do it regularly, hard to remember all details. For now, I have locked settings on the two 685 units. Hopefully the selections will stay. The TT350 doesn't have a settings lock feature.

My next challenge (once I actually use the two units together on stands) would be to see how much light power they generate and how to adjust it for correct exposure.

I am confident that the results will be different when I use them by themselves, with reflectors, or with a diffuser (umbrella). It is probably easier to get down and do it instead of thinking too much.

When you do, please share! When I got my first enthusiast DSLR, the controls were overwhelming. I did a similar thing by formatting PPT slides with instructions and printing them on 5x7 cards. After using the camera few months, I didn't need the cards anymore.

I don't use flashes that frequently.
