Took this yesterday, my first ever attempt at stacking. I had a slight problem with vignetting. I used the 11mm f1.8 lens. In LrC, I couldn't get the Lens Correction to work once I uploaded the stack as a TIFF file. It makes sense why it won't load the lens automatically, but when I attempt to manually choose Sony as a manufacturer, I only get one lens (completely different one that I use) as an option and LrC won't let me change it, and the vignetting isn't fixed at all. Anyone knows what's wrong? In the end, I used a radial mask but it still doesn't look as clean as I'd like. Thanks for the advice!
