Well it seems that the terrible terror of aperture flickering has been solved with a small sliver of plastic shoved into my lens! I’ll save that for another post! But this now enables me to shoot day time and day length time-lapses! So last weekend I spent a bit of …
Read More »Dusty sensors, image flickering and colour calibration
You might be asking – what’s been happening lately, why so slow with the updates? Mostly I’ve been battling a dust problem on the D800’s sensor, and that’s a complete show stopper when you have moving footage. Its even more of a show stopper when your sensor cleaning product makes …

Here’s another quick post if you’re interested in creating sharpened HDRIs (not tone-mapped HDRIs, which is pretty straight forward and actually LDR). The issue when sharpening an HDRI (a 32bit .hdr or .exr) is that software like Photoshop wasn’t built to sharpen 32bit, HDR images. So while most of your …

My time lapse HDR sky project has hit a bit of a snag, and that snag is flickering. When using an aperture setting of f11, I’m getting flickering due to the aperture opening slightly differently each time, a common problem with time lapse and stop motion when using auto lenses …
Read More »Update – Time Lapse HDRI Skies
I’ve had a very technical week or so and have been unable to shoot much at all due mostly to weather. Even processing images has been slowed by a recent hardware upgrade and a couple of power failures – its been pretty stormy in Adelaide lately! In a nutshell, I’ve …
Read More »3rd Time-Lapse HDRI Sky Dome
This is another older HDRI sky shot at f3.5. As a test, I developed the NEFs with -2 exposure per bracket in order to try and get more dynamic range. However, I’ve since been informed that changing exposure like this doesn’t exactly achieve much, and results in a slight loss …

So far I’ve been shooting 2EV gaps with the Promote Control for my HDRI brackets, and as the default recommended setting, this has worked fine. However a few things have made me want to test 3EV steps: Mostly unsure what the difference is between 2 and 3EV steps. I’ve heard …
Read More »Banding, broken suns, and back to 48 hours per time-lapse!
If you’re catching up, the synopsis so far for this project is: I’m creating time-lapse HDR sky domes First series of test shots have been taken Initial test animations and renders look good (one sky, where the sun was behind some cloud, didn’t suffer from clipping in dynamic range. The …
Read More »New HDR time-lapse challenges at f11
So with the first few HDR skies shot, merged and test rendered into animations, I was quietly confident that this might not be quite as hard as I thought. Not Quite! My assumption that people would prefer slightly reduced dynamic range (shooting at f3.5 iso 100) vs the full dynamic …
Read More »Camera Setup for HDR Time-Lapse Sky Capture
Camera Setup for HDR Time-Lapse Skies and Image Based Lighting Recorded this quite a few days ago and just uploaded the video now. It covers everything from the camera body to the lens, ND filters, the Promote-Control, camera settings (which may be about to change slightly) and more. Have a …
