difference between shooting B&W versus color and then switching in PhotoShop

[Don K]

I have the A6500.  What is the difference between shooting in the B&W mode versus shooting in color and then converting to B&W in PhotoShop?  Which is preferable?  Thanks.

This video might be of interest, though its tor CaptureOne the same principles apply. The author seems to recommend shooting in color then converting:

When I choose to get BW photos I set my camera on this color profile, my reasons:

1. I see the scene in BW without the distraction of color and I can compose and expose better.

2. The BW of Sony cameras is almost as cute as Fuji ones

3. In my opinion, skins look better when they come straight out of the camera.

4. I have not been able to get the same black and white on PS as I get directly from Sony.

5. Even if I could replicate the same process for that I will work extra. If I need color and BW I just shoot RAW and JPG.
