The HDR manually created. But the in camera bracketing provided by NEX-3 was used. The max bracketing supported by NEX-3 is 3 shots seperated by .7 EV steps.
NEX is not a very HDR friendly system. More bracketing options which could be provided very easy through the software is not yet supported yet even in the latest model NEX-6.
This is the only complaint I have against the NEX system so far (its almost 2 years since I ma using NEX). Since I use exclusivly manual focus I have nothing much to complaint about auto focus speed 😉
All the shots posted in this blog is using manual focus.
So elow is the HDR from 3 Bracketed shots seperated by .7EV
