Another planetary mode question

[hefy_jefy]

First, many thanks for the full video demo, great stuff, most useful and not just about BYE...

One question:

 

I now understand the planetary mode much better and I think it would be true to say that what you see in the live view screen is exactly what gets written to the AVI / JPG imagery.  You can change the exposure by altering both the "shutter speed" and / or the ISO value.  Does it make any difference in this mode which you choose?  For example slowing the shutter by one "stop" is equivalent to increasing the ISO value by one "stop" the overall exposure is the same.  In old fashioned film photography the faster ISO values resulted in larger grain size and hence poorer resolution, I doubt this is true of modern DSLRs?

Aha!  Of course, its easy to forget that what we see in Live View (and what is written to the .AVI) is the result of the so called "Exposure Sim" feature of the camera...

Thanks all clear now,

Geoff

While the two settings have roughly complimentary effects, keeping the Shutter Speed faster than 1/20sec allows for fastest LiveView Frame Capture Rates.

With my T5i, the frame rate does not appear to be affected by the shutter speed when capturing videos with BYE's Planetary mode.  It does not matter whether the shutter speed is greater or less than the frame duration.  The frame rate is about the same.

Frame rate is unaffected by shutter speed and ISO change.

 

Changes to both shutter and ISO is a function of what Canon calls Exposure Simulation. It is a simulated view based on the shutter speed and ISO selected... but frame rate is not affected.
