Module 1: The One Control You Need for Awesome Landscapes

The "Auto" mode on a camera is smart, but it's designed for general-purpose snapshots—a birthday party, a photo of your dog, a quick shot of your friends. Its goal is just to get a usable photo of something.

For landscapes, your goal is different. You want a photo of everything in the scene, from the interesting rock at your feet to the distant mountains, to be sharp and clear. Auto mode often fails at this; it might focus on the wrong thing or choose settings that leave the background soft and blurry.

The good news is you only need to learn one semi-automatic mode to take full control.

Your New Best Friend: Aperture Priority Mode

Regular bash scripts can be used in fish shell just as scripts written in any language with proper shebang or explicitly using the interpreter (i.e. using bash script.sh). However, many utilities, such as virtualenv, modify the shell environment and need to be sourced, and therefore cannot be used in fish. Sometimes, counterparts (such as the excellent virtualfish) are created, but that's often not the case.

Bass is created to make it possible to use bash uilities in fish shell without any modification. It works by capturing what environment variables are modified by the utility of interest, and replay the changes in fish.

You might not need Bass for simple use cases. A great simple alternative (suggested by @jorgebucaran) is to just use

exec bash -c "source some-bash-setup.sh; exec fish"
