If you are shooting on a deadline it makes sense to shoot in jpeg mode for faster downloading and then uploading out to your media service. However, if you are a beginner, I highly recommend shooting ice hockey in raw mode. Raw gives you a greater ability to adjust your white balance and bring out shadow detail in case you didn’t get it just right in camera.
I thought it would be fun and educational to take an image and examine it both before and after post-processing. They say a picture is worth a thousand words, so let’s use some pictures. It will cut down on how much you have to read and how much I have to type!
