"Yongnuo's gear is known for being high-quality at a great pricepoint, and this accessory is no exception. For wireless triggering and programmed timer/delay functions, the MC-36R will have you covered. This remote allows you to take long exposures, time-lapse shots, or long-delay shots just shy of 100 hours from when you set it. Time-lapse shots are created with an interval timer, which can be set to any parameters you want (also up to 100 hours between exposures). Exposure-count settings can also be used to get as many shots as you need before stopping. While this remote features wireless functionality, you can also use a wired connection to operate the camera manually.|Self-timer: Just like the self timer on your camera. The timer remote switch allows you to set any delay (in 1 second increments) up to 99 hours, 99 minutes and 99 seconds.|Interval timer: The Interval Timer can be set to any time period up to 100 hours as well. If you set it to 10 minutes, for example, one exposure will be taken every 10 minutes until either the film runs out or the Exposure Count limit has been reache|Long- exposure timer: It allows you to take time exposures up to 100 hours long.|Exposure-count setting: This setting allows you to set the times of exposures that will be taken, up to a total 399 times. For example, if you set it to 30 times, then the exposure will be only taken 30 times."
