Just posted a quick sequence of clips shot here in Arizona with an EX3 over the last few days on Vimeo.

Great timelapse. Did you use the EX Slow Shutter setting for the night lightning shots or was it regular shutter speed?

Alister Chapman · July 27th, 2008, 10:36 PM

It was all shot at 25P, no shutter for the lightning footage.

Ray Bell · July 28th, 2008, 04:55 AM

Footage looks great... looks like you found a roost on " A " mountain.. its a nice place to get great sunsets too...

Chris Medico · July 28th, 2008, 06:53 AM

That looked great!

For everyone that said the CMOS rolling shutter would prevent shooting lightning.. Watch the video.

Having grown up in Tucson, all I can say is...excellent! Reminds me of sitting in my parent house in the Tucson mountains watching t-storms roll across the valley floor from the Catalinas. Makes me want to visit home.

A hang glider, once, jumped off of A Mountain and stalled his regalo kite. His life was spared, however, by landing on the (closed) roof of a convertible cadillac parked at the base of the mountain.

Beautiful.

How cool to be able to sit on some peak, out in the open, with your metal sticks, watching nearby lightning. Glad you came back safely! :-)

Tom Roper · July 28th, 2008, 08:47 AM

I'm curious about that lightning and the non-effect from the rolling shutter on Alister's video as well. I shot some lightning on my EX1 and there was a definite partitioning of the frame in 24p in some instances, of which I didn't see a single one in Alister's. Is the EX3 improving on this?

Don't you have mountain peaks in Florida? Lol...
Never discount the opportunity occasionally presented out west from a room in a high rise hotel with an overlook.

Alister Chapman · July 28th, 2008, 08:52 AM

The EX3 handles lightning the same as the EX1. I find that 25P with no shutter gives me completely artifact free lightning 90% of the time. I do get the odd bolt that will give a partial exposure but not many. The flash from lightning often lasts more than a 25th of a second.

Yeah "A" mountain offers great vistas. Just a shame that for the moment the remnants of Hurricane Dolly have put a halt to the monsoon. Should get going again at the weekend.

When you say 'no shutter' what do you mean?

The little shutter on/off switch under the lens barrel of the EX1.

Have you been to mount lemmon ?? ( I have not ) was just wondering if there would be
any advantage on that mountain, or would you be too much in the storm??

Jim Andrada · July 28th, 2008, 06:38 PM

Alister,

It's been a rather cool Summer this year. I think only one or two days in June made it to 110.

How long will you be in Tucson?

Really nice clips - thanks for posting.

Alister Chapman · July 28th, 2008, 11:21 PM

The monsoon has taken a break for a few days so we are now going down to Tampa in Florida to see if we can't catch some waterspouts on Wednesday or Thursday. We are back in Tucson for Friday night then fly home Saturday.

Mt Lemon would put you in the storm.

No Shutter = Shutter off.

I also use 2 frame SLS shutter for lightning. This completely eliminates any split screen effects with lightning.
