I use an Aputure AP-TR3C

Aputure Limited - Digital LCD Timer Remote

As I recall, I bought mine through ebay for about $35. To get it to do brackets, you program the duration of the timer's shutter to be long enough to cover three clicks.

There were no clouds. So I can't imagine that was the problem.

Aha! You're right. Seeing that halo around the sun convinced me the sky was full of thin clouds because if I shot the same thing here, there would be no halo.

I believe that effect is due to a combination of diffusion and the brightness oversaturating the sensor. The more you expose, the wider the saturation area.

Jon,

When you bracket, the file names are sequential, so if you shoot a new still ever 8 seconds, that's 450 stills (per hour) per exposure level, or 1350 stills in total. How do you get them organized so that all the -2 exposures are grouped together and so forth?

Does my question make sense?

I wrote a Ruby program that does that for me. It's on a different computer, but I can post a link later...

One of the biggest problems with bracketing is that it's a memory hog. For long runs, shooting JPGs might be necessary.

Again, this flickers because you are using the wrong settings. If you used "M" it wouldn't flicker. In 'AV' you are asking the TTL metering to pick the right exposure time in a scene with changing light levels - hence the flicker. You certainly shouldn't start trying to bracket or use 'AV' until you have mastered 'M' mode - all you are doing is wearing out your shutter.

You make a good point, Liam.

First, get perfect timelapses in "M" mode on non-sunset scenes. In fact, start with single photos and really learn to nail the exposure with minimal clipping. (That said, the sun will always clip.)

Also, don't be afraid to use smaller apertures. But note that you will want a pristine sensor and lens to avoid spots and blemishes.

Bracketing is only needed in two cases: 1) sunrise/set, and 2) when you want an HDR effect.

And before shooting timelapse HDR, master single shot HDR.

Liam is right about wearing out the shutter. It's good to make some initial tests to get a feel for timelapse, but the goal is to get 100% "keepers".

Folks,

Here's the latest.

I shot it in Manual mode, f22 @ 1/6, ISO 160, with 5 seconds between shots. Also, I shot RAW photos instead of jpegs

It plays back perfectly smooth on my computer. Vimeo tends to stutter sometimes. Once again, I ran out of clouds. It's a Southern California thing!

I put the vignette in.


Cheers,

Sterling

Nice! (Though I see the Vimeo stuttering too, and my PC should easily be able to play it.)

Just for sh!ts and giggles, you can download it from Vimeo and see if it plays more smoothly.

I downloaded it and it was smooth as can be.

I see that it's 29.97 fps (or so I assume - Windows says 29 fps. Duh.) Try re-rendering it at 24 fps or 23.976 fps to see if Vimeo can play it back smoothly. That will make your timelapses 25% longer for the same number of clicks. :)

I found this computer controlled slider that is at a reasonable price. I'm tempted, but I'm not sure if this time lapse thing is just going to be a passing phase for me.

I found this product because this guy used it on his latest piece. It's very impressive:

Here is another option for time lapse.

This was done with a Plotwatcher game camera from Day 6 Outdoors - Maker of the Flat-Out Feeder and PlotWatcher HD Time-Lapse Video . This camera films 720p HD time lapse and only costs 149.00.
