Low resolution photos process more quickly, allowing the photographer to shoot another photo sooner. They also use less memory, an important consideration when one has an older camera, or is otherwise running low on storage space.

The Sooner State.

No, sooner is an adverb.

But there is a proper noun Sooner, a nickname applied to pioneers in the Oklahoma Territory.

No sooner met but they looked,

No sooner looked but they loved,

No sooner loved but they sighed,

No sooner sighed but they asked one another the reason,

No sooner the reason but they sought the remedy,

And in these degrees they made a pair of stairs to marriage.

Shakespeare, As you Like it

I need to leave for the airport sooner than expected.
