We’d recommend shooting in RAW + JPEG so you have the standard photo (JPEG) and the RAW copy for editing.
Your camera’s default settings will likely take pictures in JPEG format (Joint Photographic Experts Group). This is a standard image format. But if you’re serious about producing the best quality of wildlife photography, we’d recommend you also turn on RAW capture. A RAW file is an uncompressed and unprocessed image. RAW images retain more detail and information than JPEGs, but are also significantly bigger files (meaning they take up more space on an SD card or hard drive). You can think of a RAW file as literally a raw image or digital negative that will need to be processed in order to bring out the picture’s full potential – similar to developing physical negatives under red light in a dark room.
