I'm new and have some questions about this.
I'm using a Canon 7D. It has this function called "Long exposure noise reduction"
The problem i am facing now is that, if i turn this on, and if i do a long exposure......
For eg, 60 seconds..., then the shutter will open and close for 60 seconds, then take another 60 seconds to load the picture. It takes twice the time for a picture to load. Does this happens to u guys as well?
And also... If u turn it off, the picture will appear in 60 seconds straight after shutter closes.
However, i realise, for pictures over a few seconds, if i don't turn this on, then i start to have white/blue/red dots that are bigger, then small small white dots everywhere(refer to pic). Is this due to the reduction that is turned off? Or are they hot pixels, or are they dust?
Is there any way i can go about solving this? Below is a picture of it without turning on this "Long exposure noise reduction" function.
