In this case, you will have to live with the difference. Possible Cause #2: Exposure Simulation is turned off Make sure to check your high-resolution images early and often. The Canon live view DSLRs all have exposure simulation. It is either “always on”, or there is a setting to turn it on. If there is a setting, it will be called out in our setup instructions. Possible Cause #3: Using a manual aperture lens on a Canon body Just make sure you’ve followed that step. We recommend using a manual Nikon lens on Canon body, because this avoids flicker. The downside is that this can affect the live view exposure simulation of the Canon cameras. Usually you can adjust the live view to match the high-resolution images by adjusting the “Exposure Preview Offset” in the Cinematography workspace’s Camera Settings. You can read more about the problem and see another solution here. Power down the camera and then try your Nikon lens.Open the aperture as much as it can go (lowest f/stop number).Attach a Canon digital lens to the camera.Sometimes the internal live view calculation is thrown off by the last digital lens connected. If you still can’t get close with the exposure preview offset, let us know. Possible Cause #4: The sensor isn’t getting enough light. We often get calls from people who are on a dimly lit set, with their aperture stopped down to f/22, and with “Exposure Preview Offset” set all the way to “+4”, and they want to know why the live view doesn’t match their high-resolution image. This is especially problematic for manual aperture lenses, since the aperture is always stopped down. The reason is simple: the lens doesn’t have enough light. You have exceeded the limits of the live view exposure simulator (inside the camera). Use a bash light (also called a work light).This is a light that is on for the animator and video assist, but off for the high-resolution capture. Go to Preferences : Capture and set a capture delay of several seconds.Use the DDMX-512 to control a bash light through a relay.Use the DDMX-512 to control a bash light through DMX.There are a few ways to set up a bash light with Dragonframe:
