A Camera Q

To B or not to B

The B setting on cameras, you'd have thought that in this day and age
the B setting could be a toggle function as the only reason to use B
is typicall for exposures of longer duration than 15 or 30 seconds
which appear a common maximium.

So B for long exposures of 30 so how can I hold this shutter release
down for say up to an hour or perhaps longer...

Why can't the B setting be updated to a toggle function..via
firmware..or a new function added, other than wanting to sell
expensive remotes....... I can trigger my EOS M3 with my ipad but why
can't I have longer exposures via the ipad it'd be relatively simple
to program I'd have thought. Just keep sending the open instruction
to the camera for an amount of time set on the ipad.

NOSPAM what'd ya reckon up for it, although canon might have
sopmething to say about it.

As already mentioned, this is called the T (for timed) shutter setting.
I think it fell into decline along with the increase in film speeds.
(The B for bulb setting was originally used by press photographers
sharing one expensive flash bulb - they could all open their shutters
and then the designated flasher would flash ...).

Shutter release cables often have locks or clamps to hold the shutter
open. I suspect electronic remote control systems probably have a
corresponding feature.
