I have a Canon T6i - use Auto mode- with flash bracket, shoe cord and a canon Speedlite. All is fine then in September it started to overexpose the photo - not every one but many at the event. then I read on a forum that it happens with Canon Speedlites - I then got a Neewer flash, and two Godox flashes - same issues. All in TTL setting. I then got the Canon T8i - and same issues. Then I tried new shoe cords - same issue. Tried not using the flash bracket - same issue - then I tried the new camera and a different lens - same issue. I am at the end of my experiments and cannot figure the issues. Please help - I have many events coming up and need this to work. I have asked so many people and no one can seem to help. I changed batteries, I used the rechargable battery for one of the Godox. All the same issues HELP

Which versions of the 430EX and 580EX series. Canon has released multiple revisions of these speedlite units. These speedlites when mounted to your camera should say "E-TTL" if they switch to "TTL". Your speedlite is not communicating with your camera correctly.
430EX series
- 430EX original (2005-2008 Discontinued)
- 430EX II (2008-2015 Discontinued)
- 430EX III/III-RT (2015-Present)
580EX Series
- 580EX original (2004-2008 Discontinued)
- 580EX II (2008-2012 Discontinued)

Sorry AnnieO there isn't any EXIF data with these pictures. If you can find the EXIF data please post a screen shot of it separately. What is your Canon speedlite set to when this occurs. Is it set to E-TTL or TTL. The overexposed pictures look like the speedlite was set to TTL instead of E-TTL which causes overexposure. A speedlite set to TTL will always cause gross overexposure.

EXIF Data is data info about a given picture. Cameras usually use EXIF Data to show exposure settings, camera manufacturer, Lens make, lens focal length and other info about a given picture.

Actually some of your pictures do have EXIF Data attached but all of the pictures that are overexposed lack EXIF Data. Your other pictures report that you were using a Tamron lens. Did you switch out lenses during the shots.

Are these all with the same lens? That seems to be the only constant. Switch to AV mode and set f/16. Try to do a few depth of preview tests to see if the lens stops down.

The OP is using TAMRON 16-300mm F/3.5-6.3 Di II VC PZD lens in some pictures with the EXIF Data intact. The pictures without the EXIF Data intact are the overexposed shots.
