[wikitalia]

Beautiful!

[gessman13]

a fine hdr timelapse! thanks

Just like a dream.

Anyway, great job with your videos and keep trying new stuff (especially while the weather is nice up there, I lived in Ann Arbor for a while while attending U-M).

After seeing these, I might do that sooner than I thought. Trying HDRI may solve one of the problems that I have with the D200 and timelapse... frame-to-frame flicker in luminance and saturation. Have you ever experienced that? Even if I set everything to manual, sometimes I get slightly brigher, darker, or less saturated frames in there. I can clean it up a bit in After Effects, but I'm hoping that since HDRI uses multiple exposures, the flicker would be less noticeable.

After all these years I'm going to say luck comes into play. I believe a book could be written on the subject. Flicker can come from something as minute as the tiny differences in aperture due to mechanical fluctuations to allowing the camera to meter every shot. That being said, I've had great results from cameras in full auto to lots of flutter on full manual lockdown (are you locking down the white balance as well??)

This evening I'm doing an aperture priority at super high iso and I'm going to run gbdeflicker through it's paces. I've had some luck with it and some luck with HDR processing. I've also had trouble spots that both wouldn't fix so I'll throw out the luck concept again.... It's a tricky discipline!

I was talking to a very reputable pro the other day, he said the way to get rid of flicker on the nikon is to buy a lens with a manual apeture ring control on it, then snap off the control tab that connects to the camera. Even on full manual the camera willstill drive the apeture between shots, creating minor variations.

I use a canon myself, and haven't had any problems when I use full manual.

I'm really impressed with your HDRI timelapses and I'm going to have to run out and try this! I've been making short timelapse videos on-and-off since I got my Nikon D200, but I haven't sprung for a motorized telescope mount or tried HDRI yet.

good job man

[mattdolnik]

how do you go about doing the HDR in an automatic setting, exposure bracketing?

[milapse]

I stick to full manual almost all the time and simply set the bracket to +1,0,-1 EV. I believe most cameras that have auto-bracketing will simply meter then do the corresponding brackets to that meter though... If I understand your question?

[mattdolnik]

ya thats the way I tried once, it seemed +1,0,-1 EV wasnt enough of a difference in between... maybe i picked a bad location... what program do u use to compile each 3 pictures?

[mattdolnik]

...by the way i see you finally made your panning device, Now Im jealous of the two axis haha

[milapse]

photomatix. It has batch processing...

[milapse]

yes. I wish my camera did 2EV stops in three shots... instead I'd have to do five... It's not exactly 'super dynamic range' but, I like a little contrast anyway.

[Chuckumentary]

Phenomenal! yes, post them on blip tv in higher quality.

[divedave]

Amazing!

[wanderwestmichigan]

have you ever thought about hosting your videos somewhere else like blip tv? the youtube flash compression does an injustice to the quality of these videos... I want to see them in crisp quicktime video!

The verticle panning ability adds an interesting effect looking up at the trees.

[milapse]

I now know how to get just about any 'angle' of movement!! By micro setting speed ratio of the motors I can get 'x speed up' and 'x speed right'.

[milapse]

I mean... 'x speed vert' and 'Y speed hoz'.. you get the idea.

[caddymob]

Panning + HDR timelapse = freaking incredible

[Engineero]

Oooh! Spectacular colors! I'm digging all the HDRI stuff you've been doing.
