Keeping the shutter open for 30 seconds

[Eugene Lehnert]

Why can't the Scarlet camera have a longer shutter more than a second?

You can have exposures up to 16 seconds long: You need to set the camera to 1FPS, shutter to 360 degrees, turn on frame processing (sum frames) for the number of seconds that you want (2,4,8 or 16).

You should also set the intervalometer to the same number of seconds as well.

I shoot a lot of time lapses and for star photography the scarlet just doesn't hit it. Best bet to go with a full frame dslr if your looking for 30 sec shutter. Todd explained it very well, and even the frame summon option doesn't have great results.

DSLRs are still better for any timelapse project than Epic/Scarlet, in my opinion.

Dragon, on the other hand, would be interesting, but until someone has a dragon and does a timelapse piece we won't know.

For shorter exposure time lapse shots epic/scarlet works great, I use it all the time. Makes editing a breeze as well. If your shooting astro time lapse then a dslr is better due to their higher sensitivity.

Do we expect the Dragon sensor to be on par with a modern DSLR sensor ?
That's the big question, I think.
DSLR sensors don't have to read out the images very fast. Maybe that makes them better for long exposures. They don't seem to have trouble with 30 second exposures which is quite amazing really. None of that black shading stuff either.

For time lapse, DSLR wins in almost all respects. Better light response, easier to set up, lighter battery requirements, physically lighter etc...

It only looses in workflow as you have to LUT and then assemble a sequence into your format before being able to see the footage.

Thats not a knock on RED, it's just not the right tool for the job at hand.

The epic can do 360 shutter... so basically with a bit of post processing you can have an exposure that last for as long as your mag last at 1 frame per 16 seconds... thats like a few years of exposure... I think that should be enough for most time lapse practices... However such exposure would not look to pretty and it would hold a few artifacts from the sensor, but so would any DSLR.

But to me there is no still camera that even comes close to the the 16frame summing together with the 360 deg shutter...

For example if you shoot 360deg shutter and set the fps to 1fps. Then you got a few options to post process. For example you can frame sum or compound over any numbers of frames. Also more importantly you can also mix the two at any variable an by doing so post adjust your exposure in any number between you frame sum and your fps shot.

So shooting at 1 fps. you can choose to additivly mix for example 5 frames together using an additive blend mode. This gives you a straight 5second exposure at 360 deg. you can also pick out 3 frames out of 5 and buy doing so get a 3sec exposure at 0,25fps. Further more you can compound with a curve, wich gives you a motion mount effect where the motion blur is not hacked but more cinewave shaped. And this is possible to do over any number of frames... If you also add HDRx to the mix and get the A + B track out of the camera and have the possibility to compound the two separately and then mix them together to taste....

All the above, to me, really makes any still camera look like a very stupid option for time-lapse in comparison. Epic basically bring far more options and capture so much more, the only trick to it is to think a bit different.

Battery times etc we can work around the above you can not match if you camera can not do double readout and continues 360 exposure.
