Focus Stacking Issue: OLED Screen

Post by Macro_Cosmos »

So... I decided to run a focus stack of a set of exposures of the OLED screen of my phone. I ended up with 72 exposures to process.

Using Zerene stacker, I obtained drastically different and completely ridiculous results from the Pmax and Dmap settings.

What's the way around this? I think the program simply got confused, because there's not much of a difference between "in focus" and "out of focus", just the confusion orbs are larger when not in focus.

Any help is appreciated.
Thanks

MC

I lowered exposure by 2 stops making only the dots show up. Did another Pmax stack which yielded significantly better results (compared to above) which is still not good. I guess manually masking and stacking in photoshop is the only way left.

It looks to me like the computational alignment process is going crazy. That can happen sometimes when there are very regular repeating patterns that can get matched up incorrectly.

I suggest going to Options > Preferences > Alignment and tightening up the settings to be just a little bigger than what your stack actually requires. Turn off rotation entirely if your setup doesn't need that.

Thanks! I will give that a spin tonight. :)
Tried a single exposure, worked well too. Like the nice symmetry.
