Most raw files have a JPEG embedded within them, many cameras embed full resolution JPEGs. You can extract the embedded JPEG, which will reflect the Picture Style and color space settings entered in your camera at the time of shooting, by using dcraw on a directory of images.
dcraw is a command line utility, but do not let that deter you. Once you are in the directory with the image files, type the following at the command line prompt:
This assumes that the raw files have the extension "CR2" - change that to whatever the extension is for your raw files. Here you are simply saying "hey dcraw, extract the JPEGs (the "-e" flag on the command line) of ALL of the CR2 files (*.CR2, where the "*" is a wildcard for "anything" that is then followed by ".CR2") in this directory.
dcraw will chug through the directory and produce the JPEGs next to the raw files.
If you take some time to learn how to produce a script, or a macro, or command that embeds this invocation of dcraw (i.e., some automated task in your OS), you may be able to automate the process even further by being able to drag the directory of files onto the script icon, etc. to invoke the process. This is probably what is under the hood of the Michael Tapes application and, by using dcraw, you do not need to give the Michael Tapes borg your personal marketing information. Plus you can learn something about taking control of your workflow!
