How syncronize a canon 270ex ii and t4i

This is 270ex ii as a twin flash with photomed arm

A few days ago I buy a 270EX ii flash, to try to make light effects due to wireless flash capability .

I have a camera t4i/650d , I try every possible way to fire the flash wirelessly , and set and checked the manual several times and nothing is .

Sometimes it work wirelessly and most of the time no. The times that works for me with the camera in hand , I raise the built-in flash and I cover the light so I do not interfere in the picture , and flash this to no more than 30cm from the camera .

I do not understand and have not been able to find any tutorial on the internet is needed if the 270EX ii flash light of the camera to fire wirelessly ? has a light sensor that detects light fires when the main flash?

I ask that because I have a colleague and friend who does macro photograph with 2 of these flash mounted on articulated arms as a twin flash and it works perfect.

I do not understand what I'm doing wrong, if you could help me with that?

thanks


Thanks for your question about the Speedlite 270EX II. Sorry for your issues.
It drives me crazy when intermittent problems arise because they are hard to diagnose.

It is very difficult for me to answer because I am not there with you in Chile to see exactly what you are doing.

I prefer remote systems that work with radio waves instead of light waves from visible and infrared (IR) systems. Canon is moving in the right direction to switch over to radio waves for wireless, as they have done so in the Speedlite 600ER-XT.

The problem with remote triggers that use light waves to trigger flashes is that the light has to directly go from transmitter to receiver without any objects in between.

It is also possible that your 270Ex II is simply defective. Have you tried the exactly same set-up with another flash?
I would suggest that you try another flash with the EXACT SAME position for everything and see what results you get.

Personally I only use my 270ex II on the hot shoe and bounce it or Ill use it with a Canon Off-Camera Shoe Cord

Have you followed the directions in the manual carefully? The directions are on page 17 of the manual: Canon 270EX II Manual.

Your colleague may be getting good results because of the light reflecting back from the up close subject with macro photography

Hope this helps.
Good Luck
