Hi Neil

Thank you so much for all the teaching you have given on your site, I have learnt so much and it will really help with my photography. There is something that is still baffling me and that is how f-stop and ISO settings effect the amount of power from TTL flash. I’ve tried to find some explanation and have read your TTL vs Manual articles but I’m still not getting it. Please can you help? Thanks

Here is one of the articles explaining the fundamental differences between manual flash and TTL flash.

Manual flash exposure is controlled by 4 things:
aperture, ISO, distance and power.

With TTL flash, your flashgun (and camera) controls the flash exposure,
by controlling the output / power from your speedlight,
as you change the aperture, ISO and distance.

The technology works for you here.

Dear Neil,
Just bought your Off Camera Flash book and visited your site which l found both to be extremely helpful.I use the D700 with the Nikkor 24-70 mostly attached to my camera.I shoot mostly in Aperture Priority in outdoor/ street photography and Manual when in the basic home studio.I tend to use the Nikon’s auto ISO(which l limit to 1600)after setting the aperture/shutter speed to avoid changing too many settings especially in street photography.How helpful is the auto ISO setting or would you advice setting the ISO speed manually?

Meng .. I shoot in manual metering mode for the majority of times, for specific reasons. For me then, Auto ISO would just bring back something that isn’t under my control.

However, if you shoot in an auto mode like Aperture Priority, it might help in making sure you don’t fall below a certain shutter speed. But it is then something that needs to be set according to the specific camera’s capabilities.

Hi Neil ! I have a nikon d300 and a sb800 off camera flash with a firefly softbox. I would like to do outside shots with off camera flash. my problem how can i use manual settings on the camera and have the flash go off with these settings? when i have everything set up the camera stays at 125 i’d like to go up to 250 at f8 but i don’t know how. I’m used to my transmitter/receivers in studio but it’s a new world for me outside studio. If you could give me a tip on how to do this i would be very happy.
