This effect creates a simplified, poster-like image with minimal gradation between shades.

It often used for artistic or stylistic purposes.

Explanation

When a negative is underexposed, it means that it didn't receive enough light, resulting in a lack of shadow detail.

If it's then underdeveloped, the negative won't have a chance to compensate for the initial lack of exposure, resulting in a weak negative with very little shadow detail.

It helping to establish photography as a respected art form.

Explanation

When you stop down the aperture from f5.6 to f11, you are reducing the amount of light reaching the paper.

To compensate for this, you need to increase the exposure time.

f5.6 to f8 is a 1-stop reduction in light (x2)

f8 to f11 is another 1-stop reduction in light (x2)

So, in total, you need to increase the exposure time by 2 x 2 = 4 times.

8 seconds x 4 = 32 seconds
