Dear Chings , I am using 40D , how can I use B shuuter ? or I must have the remote switch to use it ?

快門轉到慢過30秒便是B快門

要用m mode,快門較到30秒,下一級就係b快門(bulb)~~
除左remote,可以用快門線~~

you can also just press the shutter, but you make face shakes when you press it

M档.快门转轮向左,向左,再向左,肩屏出现Bulb,即为B门.完全按下快门,快门打开,松开快门按钮,快门关闭.
