Fixed vignetting
Well, I've downgraded from pie just to test gcam .. Its mostly awesome except for nightsight in extreme low light, where huawei clearly wins with manual set exposure to 4s (try it out too, noticed that when you set time manually, the night mode quality gets much better). But back to gcam, I've noticed quite annoying vignetting at all circumstances. The middle of picture is brighter, more saturated and warmer than rest of image. Which leads me to my fix I created in lightroom. It was quite pain to fix, cause normal vignetting fix doesnt work, had to do some radial filters, color temperature and tint fix...

Well on phone you can try it too, but my advice is to create custom preset in lightroom, then open folder with presets in android/data/adobe ..... just paste the preset and rename it with that preset name thats already there, and delete the old one..
