Hello everyone, greetings from Chile.
I have always had a technical question about how much time I should give an object in order to have a quality photo, with as little noise as possible.
For example:
I have an object to photograph and I generally use exposures of 5 minutes, but my question is to see how many hours I give it in total to have as little noise as possible in my photographs.
Any formula, any data to help me with this?
