I have some shots of a storm that was over Newcastle and want to stack some of the images together but when I do it always turns out crap. Below is an example. I think this one was attempted with HDR stacking. Since then I have downloaded and automation process in photoshop but when I use that one the details seem to be washed out and blurry. If someone has a process that works for them or knows a tutorial about it please let me know. I would greatly appreciate it.
