Em-1 LIVE TIME

Having read in depth Darrell Youngs book I have tried for the first time whilst on holidays LIVE TIME.
I ruled out LIVE BULB, BULB, as LIVE time doesnt require you to keep the button pressed. I'm not in a position to view photos on anything other than ipad and just wondering if BULB/TIME timer - 8 mins
with monitor of -7 and Live TIME 8 secs is excessive for a nice shot of the sea/moon at night. i keep monitoring the histogram and it seems to peak at first interval is this about normail or should i be reducing the intervals to couple of seconds?
Any rule of thumb would be appreciated from someone who is more familiar with this photo taking method.
Thanks

Re: Em-1 LIVE TIME

A few points:

- Exposures longer than about 40s on the E-M1 can generate a lot of noise. If you want to do exposures this long or longer I'd suggest an old E-M5 or an E-M10. The E-M1 has a Panasonic sensor. All the other 16Mp Olympus cams use Sony sensors.

- The moon itself needs an exposure for a sunny day - 1/125 at f8 at ISO 200. The moon is in full sunlight remember! That's the reason the histogram peaks immediately. You'll have to accept this. If you want detail in the moon you'll have to take another shot exposing for the moon and then blend later in Photoshop or such like.

- If you're after exposing for the landscape illuminated by moonlight then you'll need a long exposure. The typical EV of the moon is about -4 compared to sunlight at 15. That's 19 order of magnitude difference - 20,000,000,000,000,000,000 times dimmer. If you're shooting a scene in sunlight at 1/125 at f8 then you'll need to add 19 stops additional exposure to get the same result - so say 2m at f2 or thereabouts. Of course you might want to keep the exposure darker to keep the moonlight feel - so maybe 30s at f2.

Good luck!

Re: Em-1 LIVE TIME

Thanks kind of get what u are saying so in terms of some nice dark palms with sea in background reflections from moon (moon out of shot) what in your opinion would be a good starting point using LIVE TIME. Im using my 12-40 btw.

Thanks sorry for sounding a bit slow on this topic but dont even know how long to expose such a shot, so glad It encompasses a live update on the screen id be goosed without.

One minor pedantic point... 19 stops is 2^19 not 10^19... so more like 500,000 times dimmer.

Yes, of course you're right. Oops
