I have been working on two issues today. How does the 5DSR work for TL and what to do about exposure during a light to dark sequence (sunrise of sunset)
1. How does the 5DSR work for timelapse. Answer, pretty good, but it lacks a few things the R5 has. The R5 has a way to set the exposure for the first frame and keep it constant, or adjust each shot based on exposure point. The 5DSR does not have this ability to expose each frame so it would need to be adjusted during the sequence. The 5DSR is also limited to 1920 x 1080. The R5 can go all the way to 8K.
2. I did some TL's in AV priority and the images go from normal exposure to very dark as the light fades. This does not happen on the R5 with the exposure set for each image. I also tried with auto iso and got the same results. I conclude that this feature (expose each shot on its own) is what's responsible for the even exposure from very dark to very light scenes, but it probably does not work unless auto iso is set because otherwise exposure might be out of range.
This raises a question for all of us doing TL. How do we control exposure during a TL? If we let the camera keep it constant, it does not look natural. If we turn off this feature and adjust it manually during the video, how do we avoid sudden changes including movement?
One strategy occurred to me. Shoot the TL in a series of takes with a deliberate interruption as the scene gets lighter or darker. You could start with a bit of exposure bump at the start of a sunrise, then as it starts to get brighter, stop and readjust for the next section etc. These could be joined later with a transition between sections.
One other advantage of the R5 is that it displays the image after each shot which allows you to see when the exposure is going bad. The 5DSR does not do this.
