Is it better to have a square or a rectangle between the negative film and the storage room?

As long as the storage room is negative.

There are generally two options for the selection of underground storage rooms: close to the entrance and exit of the passage; In the farthest corner.

1, near the entrance and exit of the passage: the advantage is convenient access, that is, it is relaxed and refreshing when loading goods. The disadvantage is security. If the property management of the community is not very good, then don't make such a choice.

2, the farthest corner: the advantage is safe and reliable. Generally, thieves always choose a convenient place to start, and are unwilling to go to the deeper far end of the roadway. Its shortcomings are obvious, and it is not very convenient to get in and out. In addition, when choosing the underground storage room, the most taboo is to be close to the pipeline room. Even if the pipes don't leak at all, the storage room with pipes is always wet.
