Photosynthesis is a a process, which need at least three things that can limit the process: light, water, and carbon dioxide. More light won’t help if we don’t have enough water and carbon dioxide.

Actually, most places on Earth have the same amount of carbon dioxide in the atmosphere, but a plant can only get it by opening holes in its leaves. These holes are too small for you to see without a strong microscope, but they are big enough to let water vapor out of the plant. So water is an important limit on a plant. More light is actually a problem if water is scarce, because even more water will evaporate from the plant.

This is an example of how increasing one factor (sunlight) can lead to another factor (water) being limiting.
