Flicker Suppressor released

Software
1

Hi guys!
It happened to me last year that I made a photography set for a theater company during training. Unfortunately, there were very bad strobing neon lights and I had to shoot silent with my a7III to not disturb the actors.
I struggled quite a bit and ended up using very slow shutter speeds and BW only to avoid a complete disaster. That shooting piss me off a lot and after stressful online researches, I wasn’t able to find any public tools or techniques that would allow the problem to be solved in batch within a reasonable timeframe.
So… I created my own software and here I am giving it to the community :sunglasses:.
It’s far from perfect but we have to start somewhere.

It features a very familiar GUI and deep parametrization to tackle most cases as possible. CLI usage features many more parameters if needed.
It is both statistical (AI transformer based) and deterministic (various local/global filters) and it can be used virtually on any HW, even without a discrete GPU.

Here’s some examples on public/personal material:

bad chroma shift and complex subject

Let me know if it is of any help and if you find any issue, please report it on the github page :pray:.

Good luck!

This is going to be life changing for a lot of people! Photography that isn’t possible will become possible.

Do you know if it will handle RGB banding from multi-channel LED lighting?

Wow this is awesome.

I mainly shoot nightclubs and own a Z8 so run into this a fair bit!

Normally I end up deleting photos with bad banding, but will try this out over the next couple of weeks :slight_smile:

Your camera like has flicker suppression in the firmware.

Cancer drugs could be life saving, software to edit images, not so much.

In my experience it doesn’t really help with the banding from LED’s.

I have used the “Shutter Speed, Fine Tuning” which can help fix the issue, but it’s not super ideal with the lighting in the venues changing so frequently.
