Specific parameter settings for shooting colorful pictures for 60 days

There is a B gear on the 60D, which is on your mode dial. When playing this gear, fix the camera with a tripod, press the shutter and don't let go. Take more photos by yourself and grasp the best time to release the shutter, and you will certainly be able to shoot this colorful effect. B file is a long exposure file. You press the shutter to start exposure until you put down the shutter and the camera exposure is over. Just hold it down and it will be exposed. I suggest you try it for 5 seconds for the first time, hold down the shutter for 5 seconds, and then release it to see the effect. After that, the effect is not ideal, and then 10 second, 15, 20, 30, 60, until you want the effect. I have sold Canon SLR, and I hope my answer can help you a little.
