Hi all,
Im not sure I can do this but can I turn up the gain in live view?
I recently purchased a 450d (moded) and im having trouble framing and focusing.
I can clearly see through the viewfinder but not in live view.
Ive seen a few videos and you can clearly see objects on live view.
At the moment im focusing during the day and if its the camera lens im taping the focus.
When its on my c90 mak im taking multiple frame with a bahtinov and its a bit hit or miss.
Is this camera able to turn the gain right up just to get focus etc then turn off for imaging or is this fuction only available on later models.
Thanks
Andy
