Time Lapse Photography- clouds (added one more)

22 posts in this topic

I like to monthly when I get the chance expand on something new to me in photography. I finally had a few minutes today to experiment with time lapse photography. This is a quick 15 second clip that was a proof of concept. My wife had no idea what I was up to and decided to put up our umbrella on the patio in the middle of this. I am shooting right now with the evening light so I will put that up later. Let me know if you can see the video. This is fairly low resolution but it was more a proof of concept.

Both are very cool Dan! Care to elaborate on the process a little?

Neat stuff! I think I prefer the 2nd - not because of the umbrella, but because the trees moving in the wind on the right side of the frame feel shakey and a little disconcerting to me - the 2nd seems more peaceful. Interesting clips!!

Thanks Mike and Jackie. I am working on the sunset and the impending storm so I hope to have some really cool stuff tomorrow.

Mike, I first used a simple formula based on how many FPS you want over what length of time. These were proof of concept so I only used 15 FPS which is the minimum for decent viewing. I will be working up to 30 FPS which is low end movie speed. Then you divide the length of time in seconds by the frames to find out your interval between shots.

So to make it easy using the above videos I used 15 fps for 15 seconds of clip = 225 frames.

I wanted to shoot for 30 minutes which is 1800 seconds divided by the 225 frames = 8 second intervals! Whew, easy enough.

Mike I believe Nikon has a built in interval feature in the camera. Us poor Canon guys have to use other means. I used a Pocket Wizard Multimax with allows you to set intervals right on it for timed shooting of the flash or camera. So I set 8 seconds for 225 shots in the PW.

The camera because it was partly cloudy I used ISO 100 in the first, and ISO 400 in the second and AV mode with -1/3 EC for the clouds. Aperture of around 5.6, DOF doesn't really matter here and used JPEG small with a white balance of 4800K (consistent colors and darker blue sky). Hook up the camera with a pre-release trigger from the PW to the camera and hit the test button on the PW to start the sequence. Walked away and came back 30 minutes latter to retrieve my card.

Nothing to it. smile

That is really cool, especially the 2nd. It really appears as if something sinister is moving in. Do that with menacing storm clouds and it will be bordering on frightening.

Night version, note the Big Dipper. Storm is coming later tonight but I don't know if I will stay up that late. This one is at 30 FPS, much smoother video but 300 shots for 20 seconds.

Thanks for the explanation Dan! Nikon does have that feature, but unfortunately, it's on the next model up from mine! cry

That is really awesome stuff Dan. Can always count on you to step it up a notch and show us FMers something new.

Thanks.

Nice! Love the big dipper peeking through and the changing color in the clouds.

This last one is very cool! Very moody and so much variation. What fun to do.

Sweet! All are awesome. I'd love to see a sunset done this way.

This is neat stuff! My D50 probably isn't capable, and I wonder how many shutter actions I'd use getting hooked into this....

It'd be a nice feature in my Sony P&S. Definite item to have for the next one though.

Did you have to adjust exposures at any time during (or after) the sequences? i.e breaks in the clouds?

That is really cool.

You dont get to see the clouds got thru those changes with just watching.

Very interesting

These I shot in Av mode with some exposure compensation to take care of the exposure problems with changing light. Seemed to work fairly well this way. I made sure I set a high enough ISO to compensate for the light later in the evening. The bigger factor is to make sure the color balance doesn't change to much so I used a constant K temp. I think setting your White Balance to cloudy or sunny, whatever your condition at the time of the shooting would work better than Auto White Balance. I ran a 1,000 or so shots through my camera that day but that's why we have them!

    • And if the leftists get lucky at the convention?     You aren't against human rights, like income, health care, equality, LBGTQ rights, and stuff like that, right?  
    • You scale them, no?
    •   So, why bother with locks?  Honest people won't take your stuff even if the door is unlocked.   I am in the camp that I want to make it at least a little difficult for the crooks.   Especially since three people in our family have had their houses burgled and stuff taken.
    • The result right now is not good. One way or the other the toilet needs flushing
    • Mostly I talk about this with respect to the nonsense about multiple parties or no parties some on here seem so fond of.      It is all a fantasy.   Some new party could possibly take over an existing party, like Trumpism did, or even replace it like happened back in the day but in the end there will be two parties.     Perhaps a parlimentary system with multiple parties would be better than what we have, but, in my opinion, you can't get there from here.  It's like the calls for a Constitutional Convention.   Do you guys seriously think that could happen, and that the result would be good?  
    • I haven't gone up the old Grade, but do head to Outing via Emily and NE from there, and it is really nice. Hardly any roads to go across and little to no ditch riding. I have got to try the Old Grade, as I would think it is like that. We grouse and duck hunt up there now and then, but haven't lately. Great place with lots of public land and opportunity.
    •   But yet I countered with an actual study but you think your own speculative based opinion is better. OK then.     How very hypocritical.      I would end the discussion after that last statement too.
    •     I can guess it is not for humanitarian reasons.   Mexico has about had their fill of fighting the drug war for us, and are moving towards decriminalization.  If California legalizes weed, this would be enough to tip the scales in favor of decriminalization for Mexico.       For years now, Mexico has paid an extraordinarily high price in lives and social disruption for Washington’s insistence that North America’s drug problem be tackled south of the border, where the drugs are grown and transported, rather than primarily in clinics and halfway houses at home to treat the medical and psychological issues of users. Mexican President Pena Nieto.   Successive administrations, starting with President Nixon, have demanded ever-tougher border controls, aerial-spraying programs, and DEA-backed anti-“cartel” operations in Mexico. All those efforts and sacrifices have been for naught. U.S. residents currently export up to $29 billion in cash to Mexican traffickers each year to buy marijuana, cocaine, methamphetamines and heroin.   Forcing that trade underground has taken a terrible toll on Mexico in terms of violence, corruption and social upheaval. Since 2006, when President Felipe Calderón ordered his military to join the “war” on drug traffickers, Mexico has lost about 200,000 lives and 30,000 more have disappeared,dwarfing the civilian death toll in Afghanistan and Iraq over that period.   The majority of those killed and disappeared were victims of criminal organizations, but human rights organizations also report soaring rates of human rights violations, including torture and killing, committed by security forces.   The 2016 Global Peace Index, prepared by the Institute for Economics and Peace, estimates the total cost of violence in Mexico at $273 billion, or 14 percent of GDP, with no end in sight. Direct fiscal costs of fighting the war on crime were about $32 billion in 2015 alone. Yet the United States has contributed only about $2.5 billion since fiscal 2008 to Mexico’s drug war, under the so-called “Merida Initiative.” Mexico’s pain shows no signs of easing. The New York Times reported in December that Mexico suffered more than 17,000 homicides in the first 10 months of last year, the highest total since 2012. “The relapse in security has unnerved Mexico and led many to wonder whether the country is on the brink of a bloody, all-out war between criminal groups,” it said.    
    •   But In Del's defense, he only does this on things he would like to stay as is. When you are talking about legislation he is in favor of then it is the law of the land and can't be changed. When it is something that he dislikes, it can and should be changed.
