Are you referring to the flash on a DSLR camera?

I use a Alien Bees B400 connected to a camera hot shoe. You get the countdown, then you see the screen go white to take the photo and the flash comes in 1-2 secs later to flash and then take the photo.
It's been hurting the experience for the guests when they try to jump or hold a creative pose. I usually have to ask them to not move till the flash.

It would help if you provide use details
of the issue YOU are having...
1) Type and model camera you are using
2) What is happening...
3) Is the flash ON CAMERA or a slave unit?
4) Are you using Manual settings on your camera?
... and anything else I have not thought of here.
The issue that Edgar was having I had suggested
we do a Skype call and maybe we could talk and
share screens to see what the issue was and how to correct it.
If that would help you let me know

My first thought is you are using Auto focus and
that will cause the major delay with taking the photo.
The software will send the command to TAKE the photo
as soon as the count down reached 0... if you use Auto focus,
the camera receives the command and THEN begins to Focus
and take the photo with the flash going off when the camera
actually does take the photo.
This can be a 2-3-4-5 second time from command sent
until the camera actually takes a photo.

Thank you for the reply Joe!
I will try these tonight and let you know if this fixed the problem or if we need to skype as suggested!

RE: Did you have a step by step to help solve the problem.
Yes, do not use Auto focus with a DSLR camera...
So how do you set it up so that all photos are in focus???
Start when you do your first TEST session with the camera
set in AF (AF on lens switch) and the person (you or a guest)
is standing at the normal average spot in your booth...
Start the session... as soon as the first photo is taken
SWITCH the AF to MF
This will lock that focus from the first Auto Focus photo
and all your photos should now be set in the proper
focus for your camera and flash to take the photo(s)
as soon as the countdown command is received from the
software with no delay...
Also make sure your F stop setting is not too low
that the Dept of Field* needs to help lock the focus.
