A raw time interval

[Ben Egbert]

This is my attempt at a really large time interval. I shot in raw at 2 second intervals. I used manual mode with auto iso. The last part needed a lot of rescue in ACR because of a blown sky. Next time I will use shutter priority and auto iso and expose for the sky.

I shot 1312 images, but only used 717. I processed them as TIFFs with some shadow recovery saturation clarity and dehaze. I reworked several with a gradient mask for the sky. In fact the last part was reworked again with more gradient mask.

I rendered this in Movavi at 0.1 sec duration and exported at 4k high quality and 29.97 fps. This is the smoothest cloud motion I have obtained using timed intervals. Looks like 2 seconds was the key to that.

However, choosing .1 duration I get 1.19 minute run time for 717 images. The math says it should be 24 seconds. ????

I still have a couple of glitches or jumps and don’t know the cause. The places where I added a gradient mask will also show up to the sharp eye. More work needed, but I feel like I am making progress toward a time interval method using RAWS.

1126 5DSR raws equal 42 gb.

Nice. I also noticed in a few spots, the image seems to jump - not sure if those are some missing frames. 717 frames at 0.1 secs gives you 71.7s or approx 1:12 (1:11.7). Not sure where 24sec comes from?

Thanks Jameel. This proves your formula, duration times frames. Another post said to use frames divided by 30. I changes my spreadsheet again to your formula. I did not notice that you and Jim Dockery gave different formulas.

Hey that's pretty nice Ben! It's great seeing a longer duration. And I like your idea of switching to Shutter priority on the next one so that the sky doesn't get blown out. Nice music too! Where did you find this one?

Thanks Jim, I am processing one now from this evening that is 792 images. Its taking about 2 hours to process the raws in ACR, still have 121 left.

That music is Prokofives Cinderalla Ballet. I found it at Free Music Downloader - Best MP3 Music Downloader.

I think I will reserve RAWS for special places, and shoot jpgs for more casual stuff.

Ben, unless you have clear skies which would produce banding in the jpgs, don't convert to tiff. I was only doing that on mine that had clear skies. If there are clouds, or stars to breakup a solid color in the sky, converting to jpg has worked fine for me and its a whole lot faster to process.

Yes, I just did a Raw to JPG conversion and it came out fine. But I am talking about shooting in JPG. If I am at a remote location or getting something special, I will shoot raws.
