How to change TTL flash mode

I wanted to use the flash in reversed lens and it says that change the TTL flash mode to do that. How do I change the flash from TTL mode to other mode? Thanks in advance.

We'd need some details first... Like which flash, exactly, it is you're using.

Once you reverse the lens TTL will likely not work anymore. You need to change this in the camera settings menu under "Flash/Bracketing". Select Flash control and then change it to Manual.

I assume you are trying to do reverse lens macro. If so, built in flash without some kind of modifier is gonna suck.

You really need either a ring macro flash or an off camera flash unit with built in slave or using a radio popper trigger or flash sync cord.

Thanks a lot. Worked perfectly. I have seen better results with a diffuser and the pop up flash than a ring macro flash.

Youre welcome. Pop up flash has a tendency to cause shadows if the lens used is too long.
