Canon SL3 Rebel - exposure simulation

Thaida
Contributor

Hi there!

 

I am shooting remotely with my laptop and I am using external flash with a remote trigger in a hotshoe.

I am using low ISO because flash will pop so my exposure simulation darkens the screen few seconds after the camera focuses an object.

That makes it very hard to set up the scene.

Is there a way to disable exposure simulation? I cannot find it in settings.

Is there a workaround?

 

Thank You in advance.

Are you using a tripod?

 

Sometimes when using a flash setup (with no modeling lights), I will switch to Live View and lower shutter speed and/or increase IOS to fine-tune the framing.   Then, reset back to 1/200s (whater is your max sync speed value), set back ISO and take the shot with the flashes.

 

This of course is just an estimate as when working with Live View, you're just playing with the ambient light.

Are you using full auto?   Don't !

I am using manual mode.

Auto focus,

Camera is connected to laptop with cable.

Do a reset of the camera.  The flash should not operate in M mode unless you set something up.

Ah I see what confuses You.

I did not mention that the flash is external and that I am using a remote trigger in a hotshoe.

Sometimes I use a tripod, sometimes I shoot from the hand.

 

Boosting ISO is a good idea, tune the frame in live view, than set ISO back to take a shot.

 

Thank You good sir!

I am far from being an expert on using external flash gear and strobes.  But, I do not believe that E-TTL metering works with Live View.  Live View uses actual sensor to meter the scene, while the OVF uses a separate metering sensor, which is typically located the top of the viewfinder.

 

I believe E-TTL metering relies on the actual metering sensor used when you shoot through the OVF.  Your darkened images with the Exposure Simulation just may be accurate, however.  They could be representing the scene without the flash.

Hello!

 

When I shoot the images they look fine, I just have issues placing things in a frame with a black screen :).

Exactly!  You are seeing the exposure minus the flash.  The following is from the manual for the SL2.

If you have not downloaded a copy of the full User Guide for the SL3 you can download it from the same product support page where you downloaded Canon software.
