Thanks for replying

Yeah, I thought about focus stacking is involved, but not about exposure stacking untill you told , perfect distribution of light in all area of image make sense now. (And also lots of post processing)

I'm seeing some of your images in this sub from quite a time, and sometimes just looking at images I can tell that this is image by u/dasarpan007

Can You briefly explain the technique, settings and gear involve in this kind of photography (only if You want to).
