Long Duration Exposure w/Dragon

[Zeb B]

Don't have my cam in front of me and was asked a question about doing long exposures on a Dragon - like 2 minutes or so. Can this be done, how, and are their issues with hot pixels etc?

issues, at least on dsmc1 , even 1 sec exposures are hardly useable.... if you're on auto temperature ive seen footage breath a pink hue as the fans kick in and out to regulate that temp.... some hot pixels as well.... i feel comfortable using maybe 1/8 to 1/2 second exposure but image is too poor for me after that

Dang! Thanks for the info

Look into trying frame averaging mode with the longer exposures and average 4 frames. If you use summing you can simulate long exposures (up to 16 seconds) but make sure you blackshade.

I use 1 sec exposures all the time on dmc1 never had a issue with hot pixels or hue change, Frame summing is a dark art, could never make it work and that hue change happenens. But normal 1sec exposure and 360' shutter is beautiful

Don't forget to black shade

@David, Ian and Chad
Thanks guys! They are going to probably go with Phase One IQ260 for this project since it can expose up to 60 minutes noise free raw 60mb/16bit. Was hoping to put the RED to work but horses for courses 'n such. Was worth a shot.

How are you guys using the RED for Time Lapse? Can an external invo be used? Love the CamRanger invo product on my Nikon

ya anything beyond a second its better to go with a dslr. no need for an intervalometer there is a timelapse mode in the camera.

You can get better results by NOT using Time-lapse mode on Nikon. Time-lapse mode writes a movie file. Writing out RAW nef files and using LRTimelapse with Lightroom will give you far better results.

Yup

I would second this.

I use a Mark Roberts moco rig for moving shots and it does the triggering.

For no moving TL I use reds internal tools.
