Flicker issues with Mini35/XL2 at DVinfo.net

Jeff Ray · December 5th, 2005, 12:40 PM

I shot all this with a Canon XL2 and a Mini35 adapter (the redrock version), NOT the Pro35.

But moving on, I've got some severe flicker issues.

Check it out for yourself and give me some ideas on how to fix it. I think I've got the sharpness down finally (but tell me if you think otherwise), but I got some massive flicker issues.

I just tweaked the image element before we shot all this today, so that might have something to do with it, but I'm not positive. Anyway, some possible solutions would be greatly appreciated.

jeff, it looks like your GG could be misaligned. in other words its not straight and could be wobbling just a tad bit. another cause could be using high shutter speeds.

and for future reference, and topics about another brand of adapter besides a P+S needs to be posted in the "alternative imaging" forum. you can also post on redrockmicro.com/forum as well.

Jeff.

With any of the low-cost/homebuilds, where there is chance of inconsistency across the groundglass or intermittently picking up an edge, best practice seems to be to lock off the automatic gain function of the camera to prevent it from hunting for and overshooting the subtle but rapidly fluctuating light levels.
