Tweaking HDRI skies and time-lapses

IBL gamma

I do like to talk up how great our HDRI skies are for 1-step image based lighting and how you don’t need additional lights and so on, however every project is different and sometimes you might like to tweak a few things! Over the years I’ve had a number of emails and requests, suggestions, etc for what you can do with …

HDR Footage and Frame Blending in After Effects

Here’s a quick and somewhat un-edited video I just put together on frame blending time-lapse HDRI with After Effects. Frame mixed issues with IBL Probably the only thing I didn’t really touch on in this video is the effect of frame-mixed HDRI frames on IBL, which is in a word, not good Because the frame mixing creates multiple suns, brightness varies in between …

Clamped MDRIs vs Un-Clamped HDRIs.

What are clamped or un-clamped HDRIs? I’ve been writing about this a lot lately as I think HDRIs in general are often used only for ambient lighting, when in fact if shot correctly, they can be used in a much simpler (and more realistic), 1-step lighting workflow. Originally I made a post on CGArchitect called the Effects of MDR vs …

Flickering in Time-Lapse HDR IBL

I often mention flickering as part of our time-lapse HDRI sky dome products – I don’t want anyone to have any unpleasant surprises prior to purchasing, and I’d like people to know what to expect if they choose a time-lapse that features flickering, so they can factor it into their schedule and workflow. So with that said, lets first have …

Time-Lapse HDRI skies, 9 months in… they’re finally ready!

How time passes eh? Well that went past in the blink of an eye! I certainly didn’t plan on these taking so long, but here we are! Looking back I’m glad I postponed so many times, as each time I did so, we realized a problem or improvement that I couldn’t quite look past, and that would have resulted in …

New time-lapse samples coming soon + test animation

In case you missed it the other week, free HDRI time-lapse samples were made available to download by signing up here. Since releasing these day length samples, I’ve decided that they probably weren’t the best choice, as the super fast cloud motion means there is some fairly intense flickering visible unless you make some adjustments. So be on the look …

It’s about time! …lapses (the films below I mean)

Check out the following videos by some amazing time-lapse photographers, directors and CG artists! Hopefully these will give you some inspiration for your next animation or short film. The Third and the Seventh Watch this full-CG film and weep tears of silky, out-of-focus-then-in-focus-again bokeh joy. While not all about time lapse, this film by Alex Roman is one of the …

Custom battery set-up for day-length D800 time lapse photography

For my HDR Time-Lapse Sky Dome project, I originally stuck to shooting afternoons, sunsets and dusk time-lapses as I only had the battery that came with the D800. It only lasts a max of around 4 hours. Creating day-length time-lapses required the creation of a custom battery setup – I’ll outline how it was done in case you’d like to …

Sunset to Night HDRI Time-Lapse Sky Dome

Just completed finishing up the longest time-lapse I’ve put together yet. I’m quite happy with it, as its a blend from an interesting afternoon/sunset to night, with little flickering. Its 870 frames or 29 seconds at 30fps and featured a couple of complex blends around twilight/night time. To account for changing light levels I drop from f11 to f3, which …

Free Samples for Day Length, HDRI Time-Lapse Sky!

In-case you missed it, I finally released samples for a day length, time-lapse HDRI sky dome! They are from the time-lapse below: Provided in the sample time-lapse are frames 1-586 from a full, day length HDRI time-lapse sky. The frames are provided at a rather small 1024×512 resolution, as even half resolution frames are huge in file size. You will find that depending …
