Exposure value being set but cannot be printed

[jmangum]

While experimenting with the cam.exposure_value property I found that I can set it, but cannot print it to check its current value:

cam.exposure_value = 1
print(f"Cam Exposure: {cam.exposure_value}")

...which results in the following output...

Cam Exposure: 0

I can see from the images I capture that I have in fact set cam.exposure_value to 1 (in this example), but that fact is not reflected when I query the value.
