How to install m8raw2dng to your system

This is acutally pretty easy. Just be sure to follow every step below, download all the needed files for your operating system (OS) and don’t panic! :)

The command line, console, terminal…

Well, this is different names for the same thing. As Linux user you definitely knocmd_windowsw what that is and you are most certainly even comfortable. As Mac user, you probably have used it from time from time. The app is called Terminal on Mac. On Windows you can do just fine without using the command line ever, but still some of you may know it. Here the app is called cmd.exe.

On all system you can change the directory with the cd command (cd Path). You can open a program by typing its name and pressing return. Command line tools in general will have options you can append. So it is then “name of the program” + “options” + “return key”.
Starting m8raw2dng without any options will show an information screen with version number and some short comments to the supported options.
This stuff is helpful to know and useful for testing if you encounter any problems. But you can manage without by using the droplets.

Install m8raw2dng

So you have the zip file of the latest version fitting to your OS? If not download it.
Extract the contents to somewhere you can remember and have access to. For example your Applications folder, with a subfolder m8raw2dng or your documents folder or pictures folder. I recommend to put the files (the application m8raw2dng and the two database files lensdb.ini and sensdb.ini) in a subfolder. They have to be together in the same location, otherwise the app will not find the database files.

Quick test to check if it unzipped correctly:terminal_mac

  1. Open the terminal. Navigate to the location of m8raw2dng (i.e. cd /Path/to/m8raw2dng/ on Mac/Linux and cd X:/Path/to/m8raw2dng/ on Windows (replace X with the correct drive C,D,E,…))
  2. On Windows type m8raw2dng (Mac/Linux users type ./m8raw2dng) and press return.
  3. You should see an output similar to that on the right side


What are droplets?

Basically those are files that have the configuration for m8raw2dng stored in them, so you don’t have to enter the parameters. You just drag and drop either the folders containing images for conversion or the images itself on the file icon and the rest works automatically. You can alternatively copy the droplet to a folder of your choice and double-click on it to start the conversion of that folder. The idea is to have multiple droplet files with different settings named to your preferences and using them as needed.

I created droplet helper tools for Windows and Mac which allow easier use of the command-line tool.

Installation of the droplets

There is not much to install, the files have to be stored to a convenient location (e.g. Desktop) and modified to your needs.

Installation on Windows

  1. download the m8raw2dng droplet for Windows
  2. extract the zip
  3. open the m8raw2dng-droplet with a text-editor or right-click on it and choose edit
  4. change the path in the line set TheApp="C:\Path\To\The\Executable\m8raw2dng.exe" to where your m8raw2dng executable is
  5. change the line set Params= -b -p -v -r -c -o "C:\Path\To\Pictures\" as you wish (see below)
  6. change the line set NoParams= -b -p -v -r -c as you wish (see below)
  7. save

Installation on Mac

  1. download the m8raw2dng droplet for Mac
  2. extract the zip
  3. open the m8raw2dng-droplet with AppleScript
  4. change the path in the line set TheApp to "/Applications/m8raw2dng" to where your m8raw2dng executable is
  5. change the line set Params to " -v -r -b -p -o /Users/YourName/Pictures" as you wish (see below)
  6. save

Make yourself familiar with the tool parameters so that you know what to set them to.
Step 5 is the standard configuration line which you will need most. The parameters you define as Params will be appended to the call of m8raw2dng. In Step 6 the NoParams will be used when you don’t drag anything on the droplet, but run it with a double-click.

After downloading the files and configuring them you can run the droplet with one of the following methods:

  1. put it into a folder containing RAW+JPG pairs and/or M8 DNGs and double click to process them all
  2. drag a folder containing RAW+JPG pairs and/or M8 DNGs on it to process the whole folder
  3. drag a number of (important!) RAW or DNG files on it to process them
